Now that the Jelly Bean update for the One X has been made official for atleast the GLobal version: http://www.engadget.com/2012/10/02/htc-jelly-bean-one-series/ Would I be able to update an Unlocked "AT&T" HTC One X when the update is releasaed? Thanks
|
Installing the Global version of 4.1 firmware on the AT&T-branded One X model will most likely be impossible due to the hardware differences between the different variants of this handset: [AT&T variant] is 0.4mm longer than the international model, and features a 1.5 GHz dual-core Qualcomm Snapdragon S4 (MSM8960) SoC with an integrated on-die LTE (4G) modem instead of the Nvidia Tegra 3 [found on the international model] which requires an external modem and is LTE-incompatible, and 16 GB of internal storage instead of 32 GB. You will either have to wait for HTC and AT&T to release an official version of Jelly Bean for your model, or take the plunge and root, bootloader unlock, and flash a custom ROM on your own if you want 4.1 sooner. Instructions for doing so can be found at XDA-developers forums .

Jelly Bean update for an Unlocked AT&T HTC One X?

I have a bunch of alarms on my Android phone and I want to change their current ringtone to a new one. The new ringtone is in MP3 format and is located in the sdcard. Is there any way to change them all at once, rather than opening the alarms one by one?
|
No. As far as I know, you will have to change them all manually. You may want to try out other alarm clock apps, though. I use Alarm Clock Extreme (free & paid), and while I can't batch update in that either, I can set defaults for every option for new alarms. If you really want a bunch of alarms to have one ringtone that can be updated later, you could use Llama . One of the features in that app is that you can set a ringtone to a profile (called a LlamaTone). Then when you create an alarm, you tell it to use the Llama ringtone; Llama registers as an option for ringtone selection. In the future, you only change the Llama ringtone, and all the alarms will be updated. Basically, you are creating an alias or shortcut. Edit Yes, you can! If you have root, that is. The main alarm clock app keeps all of its alarms in a SQLite database. You can run a sql query to update them in one go. First, create a new alarm with the ringtone you want ALL other alarms to use. Then run the commands below (in bold). Modify the alert to be the same as the alert you wish to use. <code> sqlite3 /data/data/com.android.deskclock/databases/alarms.db </code> <code> sqlite> </code> <code> .headers ON </code> <code> sqlite> </code> <code> select * from alarms; </code> <code> _id|hour|minutes|daysofweek|alarmtime|enabled|vibrate|message|alert|intent|no_dialog 1|15|5|0|0|1|1||content://media/external/audio/media/27||0 2|15|12|0|0|1|1||content://media/internal/audio/media/58||0 </code> <code> sqlite> </code> <code> update alarms set alert="content://media/internal/audio/media/58"; </code> <code> sqlite> </code> <code> select * from alarms; </code> <code> _id|hour|minutes|daysofweek|alarmtime|enabled|vibrate|message|alert|intent|no_dialog 1|15|5|0|0|1|1||content://media/internal/audio/media/58||0 2|15|12|0|0|1|1||content://media/internal/audio/media/58||0 </code>

I have an htc one v and there's a system update from htc. I'm trying to do the update, it needs to restart in order to finish the update. When it restarts clockworkmod jumps in and the update never finishes. I was trying to a zip update through clockworkmod but it does not work. Any ideas ?
|
Two ways to flash official update from manufacturer on rooted phone: 1) Look for flashable zip with untouched or just rooted official ROM with latest updates included. 2) Revert your ROM and Bootloader to manufacturers default and then install update You can find stock roms and instructions to revert to stock in XDA Developers Forums

I just upgraded my Galaxy gt i5800 to 2.2 froyo from the kies firmware. Why am I getting "not compatible with this device" from some apps that say they require 2.1 or 2.2? Can anyone please explain.
|
The "Not compatible with this device" message encompasses more than just the OS version. The Play Store also checks for other software and hardware components that the app's developer listed as requirements. These components can range from a minimum screen resolution, to having particular hardware (e.g. Tegra 3 chipset). You can try searching for a given app on Google Play Store website to get a better idea of the incompatibility.

I need to be able to save text (like url, sms, etc) on my android phone which can also be viewed on the Internet through a URL. Right now I use Google Drive (which takes time) or Facebook chat (by sending text to s friend and then copying the same.) App suggestions are welcome as well.

Have you tried Evernote ? You can create notes in the phone and read on the Web, and create on the web and view on your phone. The sync works perfectly!

I'd like to have a feature that allows my Android phone to change its lock mechanism automatically dependent on location. For example, most of the time I use pattern unlock when out and about but tire of unlocking it constantly at my desk at work. Other solutions are: manually change to a slide lock while at work - but must remember to revert it back after; enable dev feature: no sleep while USB charging - but is a bit of a hack; there are likely other semi-solutions... I'd like for my phone, when it detects my work zone for example, to require me to unlock using the current pattern lock only once and then automatically revert to a slide unlock thereafter, until the phone leaves the zone at which point it reverts back to pattern unlock for higher security. Is there an app or configuration that supports something like this already?

As t0mm13b already suggested, Tasker can do that easily: Condition: [Location] Task: Keyguard disable/enable For location, you can use different sources: GPS (most power-hungry variant, as it requires a permanent GPS scan -- but most accurate) network based (less power-hungry, but still requires at least WiFi -- but less accurate) cell based (least power-hungry, not to say: using almost no additional power, as the mobile cells are either used for telephony and mobile data -- but also least accurate) You can even combine them: having e.g. cell-based combined with GPS would only start GPS scanning when the cells already match. The trickier part will be the "require once" element, which will be doable with a more complex Tasker profile. If this is relevant to you, I will update my answer to include some hints on this. Other (and easier to learn) solutions might be available as well, but I'm not sure whether they can control keyguard. So you might want to take a look at Llama - Location Profiles, which can at least handle the "location-based" part quite well. And of course you can check the "other users also liked" section for these apps on the playstore.

I have a strange scenario - my <code> dalvik </code> cache is full of <code> dex </code> files - around 150MB of space, but it appears that the operating system does not recognize these files as related to any application. I installed an <code> App Cleaner </code> and it says my cache is empty. I went over some applications I use and saw that according to the OS they have no cache, but when I <code> ls </code> the <code> /sd-ext/dalvik-cache </code> directory I see these applications have <code> dex </code> files. Can I simply run <code> rm /sd-ext/dalivk-cache/* </code> to solve this? Is there any risk? Tech details: ROM: MIUI SD Extension: A2SD+ Rooted: YES
|
Don't confuse the App-Cache with the Dalvik Cache: App Cleaner refers to the App-Cache (e.g. cached files from the internet, aka "webcache", or from other components of the app), while the Dalvik Cache's <code> .dex </code> files are placed on app installation (they are an optimized version of the app code). So basically you compare apples with oranges. As for your problem: e.g. Titanium Backup offers to cleanup the Dalvik Cache. There might be other apps available providing this feature (e.g. SystemCleanup ), but in all cases this requires root -- unless you want to do a factory reset, which completely cleans the Dalvik Cache, amongst others.

I am having a problem with my phone's screen arbitrarily turning itself on. It has been going on for a while, but I finally got a logcat of it, so here it is.

You already pointed to the correct lines -- the interesting ones are the two immediately before it: <code> 10-01 18:25:44.391 V/AlarmManager( 279): sending alarm Alarm{40d4f110 type 0 com.gau.go.launcherex.theme.GalaxySTheme} 10-01 18:25:44.391 V/AlarmManager( 279): pending wakeup alarm com.gau.go.launcherex.theme.GalaxySTheme 10-01 18:25:44.411 E/power ( 279): *** set_screen_state 1 </code> So GoLauncher GalaxySTheme had requested a wakeup. I've read about similar issues before on another site with other GoLauncher components (cannot remember which ones it were -- but it were some I don't use myself). In your case, there seems to be something special with the Theme used. I take it you explicitly installed GalaxyS GO Launcher EX Themes (compare the apps package name in this url with the log message quoted above: Yes, this is the one having requested the wakeup). You could try to (temporarily) deactivate/remove this theme and see if this helps.

In VLC player there is a "faster" and "slower" button that makes the video go faster or slower so that if you need to learn something (for example a guitar solo) you can slow it down a bit or if someone is talking too slow in a documentary you can speed it up a bit. Does anyone know any Android app that does the same? I have a couple of documentaries that I need to speed up on my tablet and it's driving me nuts that I cant do it. I have tried these apps so far: VLC (neon) MX player Poweramp and a couple others Any help would be appreciated, thanks in advance!

iMPlayer+ handles this funtionality . It has a healthy number of downloads and should work.

How can I add a shortcut to a particular Google Drive document to my Android homescreen? This is the Android analog to stackexchange-url ("this question"). Using a URL doesn't work, since I don't want to open the browser and I want to directly access a Google Drive file I have made available offline. Could QuickShortcutMaker be used? Looking through it briefly, (see here) it doesn't look possible because the "intents" used by QuickShortcutMaker don't take arguments such as a filename.
|
You should be able to do this natively. Android 3.0 (and below): In your launcher, press and hold on a blank area and click "Shortcuts". Select "Drive Shortcut", then your document, and it will create a link for you. Android 4.0 (and above) Open your app drawer and jump to the Widgets section. Swipe until you get to "Drive Shortcut". Long-press and drop on your desktop. Choose the account to use (if necessary) then select the document.

I'm trying to gather data about my phone by analyzing the log files in <code> /dev/log </code> . I'm specifically looking at <code> /dev/log/main </code> . I always thought that any sane log format would be plain text, yet these files appear to be either binary or in some character set that neither I nor my Linux text editors can identify. What is the format? Here are a couple of screenshots: First, here's a snippet of the log as interpreted by <code> vim </code> ( <code> ^@ </code> refers to the null byte; I'm not sure about the other colored control sequences): Next, this is what the log looks like in a hex editor: I'm using a Galaxy Nexus running Jelly Bean. The logs were collected using root and a terminal emulator, since aLogcat doesn't seem to use root and thus can't access all logging info.

If you want sane information, I recommend sane commands :) (no offense meant, just kidding). So the question should read: How to obtain log information from an Android device? And now we are on the better side. There are multiple approaches which can be used: utilize apps to display (color-coded) log information utilize ADB (part of the Android SDK) to remotely extract the very same information use ssh from remote (or a local terminal app) to aquire the information directly from the device To fully handle this topic it takes more than this simple answer (if interested, you can e.g. find more detailed information on many web sites, or in Andrew Hoog's book stackexchange-url ("Android Forensics: Investigation, Analysis and Mobile Security for Google Android"), which I had the honour to translate into German. There are probably many other sources as well. So I will just give a few examples here to get you started: Utilizing apps The probably best known app in this context is aLogcat, available for free in the playstore (and the dev will happily accept your donation for the other variant of the same app). You'll find a screenshot below 1 . The app allows you to filter the logs, to start/stop recording log messages, and even to store the recorded snippets to your SD-Card -- of course in plain text, as you requested. Another app in this section is Log Collector, which simply tries to grab the entire available log and send it via the share menu 2 . The Android Debug Bridge (ADB) The Android Software Development Kit (SDK) includes the <code> adb </code> command for various tasks. Amongst many others, it offers the <code> adb shell </code> to execute commands on the device. Using this, you can gather your desired log information as well: Just prefix below commands with <code> adb shell </code> . Command prompt on the device Using a terminal app (e.g. Android Terminal Emulator or Terminal IDE) you can access the logs directly at the command prompt, locally on your device. A little more comfortable, this can be done running a ssh server (e.g. DroidSSHd or DropBear SSH Server) on your device, and access it from your computer. This way you can work on a big screen, while investigating your logs. Commands to access your log information There are a lot of powerful commands you can use to access your log information from the command line, and I will only give a few examples here. dmesg The <code> dmesg </code> command extracts the kernel log: <code> $ dmesg <6>[82839.126586] PM: Syncing filesystems ... done. <7>[82839.189056] PM: Preparing system for mem sleep <4>[82839.189361] Freezing user space processes ... (elapsed 0.05 seconds) done. <4>[82839.240661] Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done. <7>[82839.242279] PM: Entering mem sleep <4>[82839.242889] Suspending console(s) (use no_console_suspend to debug) <7>[82839.252410] vfp_pm_save_context: saving vfp state <6>[82839.252716] PM: Resume timer in 26 secs (864747 ticks at 32768 ticks/sec.) <6>[82842.091369] Successfully put all powerdomains to target state <6>[82842.092468] wakeup wake lock: wifi_wake </code> logcat With <code> logcat </code> , you can access many logging information -- but most times, this will require root. It has some parameters to filter the information, e.g. by selecting the log buffer to read with <code> -b </code> . Please read the information provided on the developers page on logcat for details. To give you two examples: <code> logcat -b events </code> would list up events, or <code> logcat -b radio </code> information on your device's radio modul. dumpsys and dumpstate The two commands <code> dumpsys </code> and <code> dumpstate </code> give you detailed system information: <code> $ dumpsys Currently running services: LocationProxyService SurfaceFlinger accessibility account activity <snip> DUMP OF SERVICE account: Accounts: 1 Account {[email protected], type=com.google} <snip> DUMP OF SERVICE alarm: $ dumpstate ======================================================== == dumpstate: 2012-08-18 23:39:53 ======================================================== Build: Gingerbread GWK74 - CyanogenMilestone2 Bootloader: 0x0000 Radio: unknown <snip> ------ MEMORY INFO (/proc/meminfo) ------ MemTotal: 487344 kB MemFree: 10436 kB Buffers: 14136 kB Cached: 145460 kB <snip> </code> bugreport And if you are too lazy to remember them all, simply use the <code> bugreport </code> command -- which calls all above and bundles it for a nice, humm, bug report to the developer... Of course, you can redirect the output from all those commands to a file to copy to your computer, and in most cases you should do so -- as your screen buffer would be far too small to handle it all: <code> bugreport > /mnt/sdcard/bugreport.txt </code> would be one example for that part.

This might seem a foolish question but I'm facing this basic issue on my Samsung Galaxy Y Duos (android 2.3.6). This is my first Androide device and using it only since a week and a basic issue is ruining my Android experience. While on call, if I press home button by mistake (Habit of last mobile), call minimize to top bar. This is specially painful when I need to cancel the call in urgency and I found call is minimized to taskbar, which then take considerable time to open the call and end it. Is there any way to end the call immediately (shortcut) or at the least prevent the call to minimize during call. Most basic and primary purpose of phone is to make/receive calls. I'm sure android must have taken care of that but its frustrating for me not to find that basic function.
|
Go to your phone settings menu. Under <code> Accessibility </code> , click the checkbox for <code> Power button ends call </code> . Be careful using this with bluetooth. I have accidentally ended calls because I wanted to put the phone in my pocket; I pressed the power button (don't want my touchscreen active: I might accidentally end the call!), and the call ended.

There is already a stackexchange-url ("similar question") to this one, but mine is narrower in scope and not addressed in the other question: Consider the case of an app that meets the following criteria: Let's take a file manager as an example, but it could be a different app just as easily. The specific app isn't important to this question. This app has no legitimate need to run in the background. I only need file management when I'm actively using the app. (In case my specific example does turn out to have a need, suppose for the sake of the discussion that it actually doesn't.) The fact that it runs in the background is confirmed by a system monitor . Even though I believe that it has no legitimate need to run in the background and don't want it to do so, I don't want to uninstall it. Can I prevent such an app from running in the background? Practical application To illustrate the need for this specific question, and why I'm not naming specific apps, consider what I had in mind when I wrote this question: I would like to go through my apps and decide which ones I want to run as services. Some should run without restrictions. Some should never run. Some should only run when some set of conditions is met. Using the information from an answer to this question, I could implement this--possibly by some custom scripting, possibly using Tasker, or possibly using another approach. Trying to handle this via each individual app's settings would be well-nigh impossible. Of course, if what I'm asking in this question isn't possible, then this application of it isn't viable. Notes based on the comments and answers The reason why I want to do this is irrelevant. Perhaps it's to save battery. Perhaps it's another reason. This question is about how , not why . A warning that a particular solution could have negative side-effects is useful if presented along with that solution. Saying, "It's impossible" is legitimate if true. Saying "Don't do it" isn't useful. This is not a duplicate of the stackexchange-url ("question") I linked to in my first paragraph. That question was about saving memory. This one isn't. That one said, basically, "Don't try." That's not a valid answer to this question. The specific apps are unimportant, which is why I was vague. I did give a hint as to a specific example I had in mind, but I'm looking for a general answer here. A solution must also prevent an app from automatically restarting; otherwise, it isn't much of a solution. A number of people have stated that this is a duplicate. Let me try to explain more clearly why it isn't: This question is about how to prevent an app from running in the background, which includes stopping it from restarting if killed. The answers so far have fallen into a few general categories: You shouldn't try, because doing so is unnecessary. I'm not disputing this point at this time, but "You shouldn't try" is very different from "You can't." Logically, it's addressing a different question, namely "Should I try to kill apps that I don't want to run?" Use method X to kill the app. Unfortunately, when I tried said method, it didn't prevent the app from restarting, just like others predicted. So, it isn't really an answer. Ping the developer/it's a bug. This is the most useful of the suggested solutions, but my question was looking for a generic solution. The other questions that this question has been said to be a duplicate of cover the same ground as in my previous point. Thus, my specific question has not been addressed, despite many claims to the contrary. It's appearing, however, that the answer is a simple "You can't". There's a related question on meta. In stackexchange-url ("Jeff Atwood's answer"), he says in part, "It's generally sufficient to link to the other question and explain why it doesn't meet your needs." The whole thread is apropos to this question. I've done this since the beginning, and provided further details in subsequent edits.

tl;dr It's ok if the app in background is just an activity. Activities just consume some memory are usually not able to run computations in the background. Therefore no CPU or battery is used for them. But if the app in background is running a service: Ping the developer Ping the developer! One of the greatest daemons that come with Android are Services that run in background for no reason or when a simply interval check with Android's AlarmManager would be sufficient. We need to kill them all with fire and not by ignoring them. Everything that does not involve a fix by the developer is just a dirty hack that by experience will result in other negative side-effects. Activities that run in Background Pure Android apps and their activities usually stay around in memory for a while after they were put out of view. But at some point they may get deleted by Android's ActivityManager if there is an ongoing memory pressure. This is intended behavior, we (the users) want it that way and it works good in recent Android versions. stackexchange-url ("Therefore there is nothing wrong if you see your file manager hanging around in memory.") Services that run in background But , if it's a service that you see running forever without apparent reason (and without the possibility to disable the service somewhere in the Apps settings), you should contact the developer . In 99% of all cases, there is no reason to waste your precious memory by doing so. Android provides with intents and the already mentioned AlarmManager enough facilities to avoid long running services. Sometimes developers will response with "but Google Maps does that too" . I argue that this is never an excuse to point at others, plus it doesn't provide a valid reason to run a background service.

I have a Samsung Galaxy Y and Google Chrome for Android is incompatible with my Phone, so I am not able to test it. Can someone tell me as to whether Chrome Web Store and its apps are available in Google Chrome for Android too?
|
The short answer is: no, Chrome extensions (which are packaged as .crx files as mentioned below) are not supported on Chrome for Android. This is answered in detail by the Chrome Web Store FAQ: Will apps work on Android? If your app is pure HTML, CSS3, and JavaScript and is hosted on your servers there is a good chance that it will work in the browser on Android. However, .crx files (including packaged apps) are not supported on Android. Users cannot install their apps onto the Android browser, but they can most likely use those apps by directly accessing the app's URL. https://developers.google.com/chrome/web-store/faq#faq-app-19

I have rooted LG P500 (Optimus One) running stock 2.3.3. I recently updated to unofficial CM10 (Android 4.1) and observed few serious issues. I observed that Google's My Location service was not working. Many apps like My tracks, Endomondo etc which were compatible with other phones with 4.1 were said incompatible. All microphone related apps were not working. After several hours of breaking my head, I understood that my /system partition was absolutely full. It had only 4kb of free space out of 190MB total capacity. With my investigation I found that few files were not copied to the <code> /system </code> partition during the ROM installation and Gapps installation. Many troubles are the result of such missing files. My questions: <code> /system </code> partition: it is 190MB in total size. Who or how it was fixed as 190MB? Can the size of partition be increased? I tried a tool but did not help. After all the process completed without any errors, I still see no change in the size. Are there any other ways to do it? Hephappy, a ROM developer had commented in XDA page as "No space: P500 has 190MB for system partition." and hence he withdraws the plan of developing JB ROM for P500. Is it then a hardware limitation? After all these issues, I switched back to my stock 2.3.3 and I still see my <code> /system </code> partition as 190MB but with lot of free space. Does this mean that 190MB is sort of hardware size/limitation? If it is so, then this would be one of the serious factors that are to be considered while buying the phone as the hardware in other means can accommodate the needs of JB except the <code> /system </code> partition size, which is a real shame. Update: Few screenshots carrying frequently asked info taken in CM10 ROM: Free internal storage = 47Mb: <code> /system </code> partition size = 190Mb. Ext2 partition on SD card created to create symbol link for few apps that cant be moved to SD card:
|
This will not change the partition size of <code> /system </code> , but uses another approach: Limit the data placed on that partition. So here's what I did before flashing CM7.2 on my Milestone²: download the file to flash. This is usually a <code> .zip </code> file (otherwise, the following won't work) open the <code> .zip </code> with your favorite archive manager (alternatively: unpack to an empty folder) look inside the <code> /system/app </code> folder of the <code> .zip </code> and remove apps you can live without (make sure not to remove any app that's really needed by the system, like e.g. the launcher). This could e.g. be the Calculator, LiveWallpapers, GooglePlus etc. Copy those <code> .apk </code> files to a separate folder outside the <code> .zip </code> if unpacked to an empty folder, now zip it up again As you removed a lot/couple of apps from <code> /system </code> , flashing will require less space there, and no essential parts should be missing any longer. Now if you still want to use e.g. GooglePlus, you can install it via the Playstore (which should place it below <code> /data </code> , so no prob) or, if not found there, use the copy created in step 3 to install it manually (for this, make sure install from other sources is enabled in your settings). If in doubt whether a file is really needed by the system itself, better leave it (or at least ask first). But I'm pretty sure you will find enough "easy removables", so you won't need to touch those. Before flashing, you could unpack the <code> .zip </code> to an empty folder and check the size of <code> /system </code> (best: make a "before" and an "after" check). It should occupy less than 190MB (better give it some additional safety margin, say "less than 180MB") for your action to complete successfully.

I've seen a few guides on how to unlock the Galaxy Nexus to prepare it for rooting, and they say that the <code> fastboot oem unlock </code> command will "wipe your personal data". I'm a little unclear on what gets wiped during this step. Is it just the <code> /sdcard </code> area? is it everything but <code> /system </code> ? Something in between? I know that <code> adb backup </code> can (at least theoretically) back up everything except <code> /system </code> while unrooted (see a recent question of mine). But I wonder if I would need to do an <code> adb restore </code> of everything after the unlock step in order to keep all of my data and settings.
|
Both <code> /data </code> and <code> /sdcard </code> are erased when you do <code> fastboot oem unlock </code> . So you lose not just files on the "SD card", but all installed applications and their internal settings and data. Yes, you can use <code> adb backup </code> to backup your data and then restore it later, either with <code> adb restore </code> or Titanium Backup Pro. However, when I did this (using <code> adb restore </code> ), my MMS messages were lost; it seems that the backup didn't save them, though maybe I just did something wrong. There's also a way to root without unlocking your bootloader. Once rooted, you can use BootUnlocker to unlock it without wiping data.

I've got a Sprint HTC EVO 4G Wimax. I want to get rid of the Sprint Apps to free up some space on the internal storage, but otherwise leave the phone stock for now. I followed the instructions at the HTCdev website to unlock my bootloader and I installed Superuser from the Play Store. If I can get an su binary installed, I can give root to Titanium backup and remove the Sprint Apps. There is a zip file at androidsu.com that I think I can flash, but that's the bit I haven't figured out yet. Since I've got an unlocked, but otherwise stock phone, I guess I don't have a recovery image, since if I boot into recovery mode, I get a red triangle with an exclaimation point. What are my options for recovery images? Is there anything besides ClockworkMod or Amon Ra? If I go with either one, how do I get it installed? Or is there a better way to get this done? Update : I Installed Amon Ra and used it to flash the su zip file. I removed the apps that I could without breaking anything. I didn't free up any space I could use at the moment, but I'm happy to have them gone.
|
What are my options for recovery images? Is there anything besides ClockworkMod or Amon Ra? A third popular option is TeamWin Recovery Project , usually referred to as TWRP. If I go with either one, how do I get it installed? Since your bootloader is unlocked, you can use fastboot to install a recovery if you download it in .img format. You do this by downloading the recovery image to your computer, plugging in your phone, and executing: <code> fastboot flash recovery /path/to/recovery.img </code> from a PC command prompt while your device is booted into fastboot mode. Alternatively, ClockworkMod and TWRP can both be installed from apps on rooted devices. For ClockworkMod you can use ROM Manager and select the "Flash ClockworkMod Recovery" menu option. TWRP can be installed using GooManager by selecting the "Install OpenRecoveryScript" option in the app's settings menu. A third option is to get a copy of the recovery you want in a bootloader-flashable zip file. For the EVO it will be a file named PC36IMG.zip. You put it on the root of your phone's SD card and then reboot into your bootloader and it should flash it for you. I know that Amon Ra has been distributed in this format, but I'm not sure about the others.

I carry two Android devices: my Nexus S phone, and a Nexus 7 tablet (both running Android 4.1 "Jellybean"). The tablet has Wi-Fi, but no cellular radio; so in order to use the Internet with it when there's no Wi-Fi hotspot nearby, I have the phone set up for Wi-Fi tethering: it effectively becomes a Wi-Fi hotspot, and the tablet uses that for Internet access. This works perfectly. However, I recently discovered what appears to be an alternate method of tethering: Bluetooth. Both devices have menu options that seem to allow it; here's screenshots of how I configured both devices: Options on Phone and Tablet (click images for larger variants) I tested this by turning Wi-Fi off on both devices, then opening the browser on the tablet and refreshing the page that happened to be loaded. I saw a message that said <code> Unable to connect to the Internet </code> I was, of course, hoping to see the page reload. It's a shame that I cannot get this to work, because it promises one advantage over Wi-Fi tethering: easier security. I want to prevent other people from stealing my bandwidth; with Wi-Fi, this requires that I set up a WPA password, and then get that password onto the tablet somehow (which is quite tedious). But with Bluetooth, all that's required is that I "pair" the devices, which I've already done. So I am wondering if I'm doing something wrong, or if this feature simply doesn't work.

My phone is a Samsung Galaxy S2 flashed with stock ROM - ICS v4.0.3, carrier is Virgin Mobile (model #GT-I9100M). There is some bloatware installed by Samsung, which causes minor problems, such as being listed in the apps list, so it takes more time to find the app I need asking for updates every now and then. I've read on the internet - there are several ways to solve the problem with bloatware, but I am not sure which one addresses both of my concerns. All of them require rooting - so I booted into recovery mode and tried to proceed according to this article: http://forum.xda-developers.com/showthread.php?t=1501719 . I got the error "failed to mount /sdcard", googling for it resulted in some vague answers. I believe this is showstopper - so I cannot do anything about bloatware without rooting - please correct me if I am wrong. Supposing I managed to root the phone somehow, there are couple options: remove bloatware (many apps on the market can do it, even for free). freeze bloatware (something I can do, for example, using Titanium Backup). What's freezing? Does it remove the app from everywhere, like it never existed? How stable is it, i.e. can any action cause them to accidently unfreeze? What are the risks associated with going along each path? Will I be able to upgrade my ROM, when the new version comes out (ICS 4.0.4 and then Jelly Bean - 4.1.1)? Do I need to backup my phone and what are best ways to do it? Just so I can restore if something happens, without paying for the fancy features I don't need. There are a lot of backup solutions out there, my main concern is reliability and, for some of them, it suffered in the latest versions and people started complaining in the reviews.
|
A backup never is a bad idea, so right after you get root access, you should: Do a full NANDroid backup (which creates images of your partitions, so you always can revert to this state by simply restoring them) Use Titanium Backup to make a full backup of all your apps and their settings (so you can re-install a selection when needed) Freezing does not remove anything, and it is fully revertible. I always recommend to first freeze a single app, then check for potential side-effects, and only remove it if there were none. Titanium Backup even offers to create a homescreen shortcut to freeze/unfreeze an app (like a toggle: If frozen, the app gets unfrozen and vice-versa), which is nice for apps you rarely use but which always annoy you (for me, this is Google Maps, which I need maybe 2-3 times a year but is running permanently in background -- so I freeze it when not needed, and simply unfreeze it when I need it). Basically, freezing an app simply hides it away from all activities. I'm not sure how that works technically, but I compare it with the "execution flag" of a Unix/Linux binary: If not set, the binary does not get executed. So no background services or any other activities from this app, though it is still installed. In short: Freezing is the safe variant, as it easily can be undone. It also doesn't touch the apps data. Removing an app is final: without a backup available, it's simply gone, including its data.

Have a look at qemu. Apparently it's known to run on ARM. Running XP (if it even works) is probably not going to be a pleasant experience due to what's noted by Chris Herbert and the probable lack of a screen/pointer driver. If you really want to do it maybe wait for the Intel Atom (x86) based tablets. There should be some Atom based Windows 8 tablets about now. The androids are coming soon.

I've recently bought a Samsung Galaxy Pocket with Gingerbread (Android 2.3). I expected Japanese not to be there as an input method, although Korean is there (why Korean and not Japanese and Chinese?), and anyway, I looked for apps that allowed me to type Japanese. I found Google Japanese Input and Simeji. Both look wonderful... in the screenshots. I haven't tried any yet. The reason is that every time I try to turn them on, a warning appears that says (translated from italian): Attention: this input method can gather all digited text, including password, credit card numbers and other personal data. Continue? I didn't accept, but this means I cannot type Japanese. What is the exact meaning of this warning? I mean, other than the literal meaning that I can understand. Why should it take my credit card number, if and when I type it? Or my passwords? Or am I missing something?
|
Basically, it's saying that the app could potentially steal your information, as it's a keyboard and therefore processes what you type. For instance, if you typed your password in and it was malicious, it could potentially record that (and everything else you type). Of course, you could trust Google wouldn't do that...Android is simply reminding you of the risk. The FAQ for the Hacker's Keyboard addresses this: http://code.google.com/p/hackerskeyboard/wiki/FrequentlyAskedQuestions#Why_is_there_a_security_warning_when_I_activate_it ? The warning can be found in the Android source (see line ~2687): https://android.googlesource.com/platform/packages/apps/Settings/+/8272edba7d10b508cbbedfce5504862da6ec9acd/res/values/strings.xml

The issue occurs in Google Reader app too.

I finally came across ServeStream , a free app in the Google Play store. It offloads podcasts and the like nicely into the background while you continue to use other apps on the device. One great thing about ServeStream is it's open source, so you can play with the code if you wish.

I'd like to get Google Now on my (rooted) Verizon Galaxy S3 without flashing Jelly Bean on my phone. Is this possible? Although I'd love to have Jelly Bean, I want to avoid flashing ROMs (and unlocking my bootloader), because I don't want to lose all of my apps and settings every time I do an upgrade. So I'd like to continue to receive stock OTA updates so that I can keep my settings intact while upgrading. I did find this method, but I'm not sure I understand the implications. It mentions flashing a Google Now ROM to your phone. Does that mean I would lose my current settings? Does it mean I would have trouble later doing an OTA upgrade to Jelly Bean? Would I need to unlock my bootloader?
|
If you follow the method found in the LifeHacker article, you would indeed need to root your phone, which would mean that you wouldn't be able to receive OTA updates, unless you were to later un-root your phone, going back to the stock firmware (ROM). You wouldn't necessarily lose your current settings, but you would have trouble upgrading to Jelly Bean via an OTA upgrade unless you un-rooted, as mentioned above. I'm sure you would have to unlock your bootloader as well, prior to rooting, although I'm not really familiar with your particular model of phone.

Use this: <code> am start -a android.intent.action.MAIN -n <package_name>/<full_class_name> </code> To control an app, you'll have to put correct values of <code> <package_name> </code> and <code> <full_class_name> </code> in the command. For example, you can use <code> com.google.gmail/com.google.gmail.check_mail </code> (Hypothetical names) as last part of command. stackexchange-url ("Obtaining package name of an app is easy"), but obtaining class name of action isn't. There are two problems: Many app developers keep class info private. Not all developers do smart modular programming. Its good habit to divide an app in multiple classes which could be triggered by intents, but not all developers are smart. Solution of 1st problem: Decompile the app using apktool and see all info.

Windows follow some specific way to boot: Start System > BIOS > Load Boot loader > Load WIN Kernel > Load WIN Shell > User > Application. How does the typical Android boot process work? When comes the "Dalvik VM" into play?
|
Boot process of embedded system is similar to PC from overview level, but slightly different from microscopic level. Here's the boot process of an Android device: PC-BIOS/BootMonitor, MBR and GRUB/LILO etc are all combined in one <code> Boot Strap Firmware </code> called <code> Bootloader </code> . Its <code> init.S </code> initializes stacks, zeros the BSS segment and calls _main() in <code> main.c </code> . The <code> main.c </code> initializes hardware (clocks, board, keypad, console) and creates Linux tags which in turns loads Linux Kernel image in memory. Linux Kernel sets up the system, loads drivers and starts running the first process <code> init </code> . The <code> init </code> process involves setup of File System (mount points of <code> /sys </code> etc are created at this point) and execution of <code> init.rc </code> . Execution of <code> init.rc </code> : It is boot-up script which uses Android-Specific syntax. <code> Zygot </code> process in init.rc brings up <code> Dalvik VM </code> and starts the system server. All these are happened before Boot Animation is displayed. For more details of processes, check out this article: http://www.androidenea.com/2009/06/android-boot-process-from-power-on.html

Will I receive Google updates for my Galaxy Nexus if I replace stock recovery with CWM (like explained in stackexchange-url ("Why isn't Clockworkmod Recovery “Sticking”"))?
|
Having CWM installed won't prevent your phone from noticing that an update is available, but it may prevent the update from installing in the usual automated fashion. The update process actually works by creating a special file with a "script" for the recovery to run, then rebooting to recovery; CWM will just show its menu instead of running the script. It may be possible to apply the upgrade through CWM as an ordinary update zip, but if you want to make sure the process is seamless, it'd be a good idea to flash back to the stock recovery before installing the update. BTW, the JRO03O update for the Galaxy Nexus removes the automatic stock recovery flash that you linked to. You no longer have to do anything special to keep CWM installed when running stock.

I don't have good cell reception in my house and I'd to have my Google Voice number forward to my phone on Wi-Fi when I'm home. Can I just use Google Voice or do I need a third-party app to do the connection?
|
You need a third-party app to recieve Wi-Fi calls. Two popular apps are GrooVeIP (paid & free) and Talkatone (paid). You could also set up Sipdroid (free), which will set up the SIP forwarding using pbxes.com. Or you could use a number of other SIP apps and set up forwarding yourself, but that gets a bit convoluted.

I created a route using Google Maps and exported it as a KML file. I would like to import now this KML file into OsmAnd so I could check where I am. So far I found out that it is possible to create a map from a KML file with theOsmAndMapTileCreator program. However, I cannot find one, all I have is OsmAndMapCreator -- and this program does not allow me to import KML in the first place (at least I don't see such option at all). Thus, I cannot prepare a map for OsmAnd (from KML; in general I prepared regular OSM map for OsmAnd using this program). Since I didn't find any working solution with true off-line KML route imported, I use Google Maps with a pre-loaded route. There is a catch though - if I forget it is cached, and I switch anything in Google Maps I will lose this route when biking. So it is not reliable enough -- just workaround. The bottom line is -- I have KML file, I have OsmAnd, I would like to import the former into the latter. How do I do it?
|
I almost forgot about my own question, meanwhile I found perfectly working solution -- simply converting KML into GPX with GPSBabel: http://www.gpsbabel.org/ It is open source, which is great plus for me.

I just read about the remote USSD attack . My hoary old Samsung i7500g phone is vulnerable (confirmed via this site ). The solution is to install a (free) secondary dialer, like Dialer One. Unfortunately, since my phone is running on 1.5 (I know, I know!), I can't download any apps through Google Play. Furthermore, an alternative download on AndroidDrawer told me that "this app is not compatible with your phone" -- presumably OS related. Okay, so, what are my options? Is there a free dialer I can use that will, as explained here , at least prompt me which dialer to execute the command with?
|
I just tested my own phone by loading Dylan Reeve's web page and to my surprise the Lookout app I have installed stopped it. I guess Lookout also functions as a dialer. According to this page there is a version that supports 1.5 (although I'm not sure if that version does include protection from USSD attacks). I haven't tried it myself but, according to stackexchange-url ("this post") you can download apk files from the play store to your computer. If you succeed just stackexchange-url ("copy the apk to your phone manually and install").

I have a Samsung Galaxy Y phone, I use the Android App called as "Any.Do" to help me with my To-do list management. One of it's widgets called as the "Any.Do Grande (4x4)" occupies the whole of my phone's homescreen. Now, I know that the screen size of my mobile is relatively smaller than most android mobiles available in the Market. So, my question here is: If a widget occupies the whole screen of my mobile, will it do so for mobiles of various different screen-sizes too?

According to the android developers guide This grid can vary by device; for example, many handsets offer a 4x4 grid, and tablets can offer a larger, 8x7 grid That being said, most phones have a 4x4 grid. One exception that I know of is the Galaxy Note which has a 5x5 grid . Also I've read about custom ROMS or mods that change a default 4x4 grid to 4x5 or 5x5

For each email I have to scroll to the bottom of the email and select "Load more details", then the email loads in HTML and all the hyperlinks are converted to graphics. On my old Evo there was a setting where I could choose to receive emails as text or HTML, but I haven't been able to find that setting in the stock email app on the S3. Does anyone know if this is possible?

There's a "Message format" setting located at Settings > [account] > Sync settings > Message format . The choices available are "HTML" and "Plain text." Not sure whether that will necessarily solve your particular problem, but perhaps try giving that a shot.

On my HTC One X, my home screen has an HTC Clock widget on it. When I unlock my phone, the time displayed on the clock shows the old time (when the phone was last unlocked) for about 2-3 seconds, and only then updates to the correct time. The system time (as seen on the lock screen and in the status bar) is correct at all times, so for a jarring moment the widget and the status bar are displaying different times. If I place an HTC Clock widget on a panel other than the home one, a similar problem occurs: the clock is not updated until a few seconds after that panel is displayed, at which time it 'jumps' to the correct time. Is there anything I can do to fix this? Is this a problem unique to the HTC Clock widget, or would this also happen if I used a different app? edit this behaviour remains the same in Airplane mode, so it's not a network latency issue
|
Following an OTA upgrade to Android 4.1.1, this problem appears to have been fixed. On unlocking, the clock widget immediately shows the correct system time.

I like to be able to charge my phone from any PC I happen to be using. With my previous HTC Android, I could default to "charge-only" and only switch it to "mount as disc drive" when I wished to, on my own machines. Why? Being prompted for driver installs (at least on a Windows machine) is annoying; connecting a storage device to a PC I don't own may be against policy/protocol/politeness. It would appear that the Galaxy Nexus uses two protocols, MTP and PTP; I currently have only MTP switched on, but can't turn it off. I could try to find a stackexchange-url ("'"USB" cable that only connects pins 1 & 4 ... [to provide] ... power and no data'."). But this would mean carrying two different USB cables around. Any other solutions?
|
This feature is called "fast charge", and it charges your device slightly faster by disabling the USB data capability. It's not available in the stock ROM that I know of, so you need a ROM and a kernel that you know supports this. I'm using AOKP with the Franco kernel and it works great on my Galaxy Nexus, so you could try that. (There's even a quick toggle for fast charge available). There's probably not an unrooted solution for this. Being prompted for driver installs (at least on a Windows machine) is annoying It might be good to know that installing the correct USB drivers for the Galaxy Nexus in Windows is not something that happens automatically. If you decide to root and flash your device, you'll encounter this; I highly recommend using Galaxy Nexus Toolkit to make the procedure as easy as possible (it's really not that hard).

I have an unrooted Verizon Galaxy Nexus, just recently upgraded to Jelly Bean. One of the touted features of Jelly Bean was the addition of the "Restart in safe mode" option from the power menu. (Long-press power button.) However, no such option is available. In fact, it's the exact same options I saw under Android 4.0.4 (Power off; Airplane mode; silent; vibrate-only; sound on). Is there a setting I missed? Or is this really a hardware option for the Nexus 7?
|
On the Nexus 7 there's not a separate menu option for "Reboot into safe mode". You have to long press on "Power off" and then the safe mode dialog appears. I'd try that, since I imagine it would work the same way if the GNex supports it.

Awesome Drop does exactly what you are looking for. Drag and drop into a page on your pc's browser and the are automatically downloaded to your device. Edit: Here are a couple other options: Wifi Syncr : If you are connected to the same wifi network this will do exactly what you want. You basically setup a shared folder in Windows and anything you put in that folder is pushed to the designated folder on your device. It's a one way sync: PC => Device. You may be able to set this up to work remotely over the internet if you use a Dynamic DNS service but I don't really know. You can use a cloud service like Flow mentioned in his answer and couple that with an app that will automatically keep the local folders on your device synced so you won't have to manually download each file. I personally use DropSync with my Dropbox account . I've also used FolderSync with Google Drive (FolderSync actually syncs with tons of cloud services). Both are paid apps but have lite versions that limit you to one folder which would work. The drawback to this method is that there is a way to set it up to detect changes on your local device and sync immediately, however it can't detect changes to the cloud directory so files would only be downloaded to your device on the sync schedule you setup.

I recently bought one new Samsung Galaxy S 2. (Ice Cream Sandwich) I am getting "media scanner running" message each time I try to open the camera. How can I get rid of this issue? Do I need to replace the phone?
|
The message means that your internal and/or external SD card are being scanned for media files. If you have recently added a lot of files, this can take some time. If this is not the case, the indexing might be broken. I'd suggest backing up your data from the phone's internal storage and your SD card, formatting both and trying again. If the problem persists, do a full factory reset. Otherwise, try adding the data from the backups to the phone and see if the camera still works. If i remember correctly, you can find the setting to format the internal memory in <code> Settings -> Storage -> Internal memory -> Format </code> and the full factory reset in <code> Settings -> Security -> Factory reset </code> , but these depend on your Android version and might be relocated somewhere else.

When switching on the phone, one is by default asked to enter the SIM-PIN -- which is a good security measure, to prevent "strangers" from causing you costs. Now the same applies when returning from airplane mode: one has to enter the SIM-PIN again. Which renders certain energy-savers useless: if an app e.g. enters airplane mode on signal loss (see: Cell standby and how can I keep it from eating my battery? ), it would be unable to return to normal operation without user interaction. I'm looking for a way to selectively disable this: Have the PIN request active when powering up the device -- but not being asked for the SIM-PIN when returning from airplane mode. Please do not confuse this with "keyguard": I'm not asking about the screen lock (PIN/pattern/password). Here I know my way around, as there is an API for apps to use (so I can e.g. temporarily turn this off with Tasker ). I know this works with Samsung devices -- but I preferably want a device independent solution which works for all manufacturers.

DISCLAIMER This needs root. No way around that one. Your device must be running Android 4.1+ This workaround may be too advanced for some users. Only try to apply it when you know what you're doing. I'm not to be held responsible if something goes awry or Ragnarök starts during the process. You're doing this on your own risk. Proceed with caution. I'm not the author of or otherwise affiliated with any of the mods mentioned. I merely found this and I'm sharing it for your benefit. WORKAROUND I found a workaround for the problem that's working beautifully on a Samsung Galaxy S2 with Cyanogenmod 10.2 and Dorimanx Kernel 9.41 installed. The necessary steps are as follows: Make sure your device is rooted. Download and install Xposed Framework Installer . When Xposed asks for root anywhere in the near future, grant it . Open the app and click on <code> Framework </code> -Tab. Click <code> Install/Update </code> . Reboot . Download and install Jelly Bean 4.x Airplane Mode Helper . Open <code> Xposed Framework Installer </code> -App again and select <code> Modules </code> . Tick (set active) <code> Jelly Bean 4.x Airplane Mode Helper </code> . Reboot . Open <code> Jelly Bean 4.x Airplane Mode Helper </code> . Tick (set active) Enabled . Reboot . That's it! Airplane Mode should work again as in previous Android versions and does not ask for SIM-PIN any longer when being turned off. It still does at startup, though, thus keeping your SIM-Card somewhat safe. I set up an automated battery saving procedure with Llama Location Profiles similar to the one described stackexchange-url ("here") (Thx a bunch, Izzy) and it's working flawlessly. Good luck, folks!

I'm baffled - my Samsung Galaxy Note running Android Ice Cream Sandwich ICS 4.0.4 has a default email client - which is rather neat.

I tried googling, but with so many generic terms - it's hard to find proper keywords.

If it's not available in the app settings, the functionality most likely simply isn't there. There are other clients you can use if it's important to you.

I backed up one galaxy S3 and did a restore on another. Then I try to boot the new one and I get a message "Unfortunately the process android.process.acore has stopped". After hitting OK a few times I get Unfortunately TouchWiz has stopped. Then back to the first message. I can't get past this msg. I thought that maybe I should do another Restore but I can't get to anything cause this happens as soon as I boot.

In short, never ever back up system apps and settings from one handset and restore to another, that is exactly what happens! :) Mismatches with system app's key signature conflicts with another's ROM's key signature, and variants of settings as well may not exist on the other, all of those can lead to breakages such as what the OP is experiencing. The only way to get that back, is to perform a factory reset to restore everything back to its original state.

Using Jelly Bean, 4.1.1, on a Galaxy Nexus, I want this: You lock the phone. For the first 5 minutes, if you try to unlock, you can just slide and unlock it; after that, you have to enter a pattern. I don't know how to get the slide to unlock to be activated for the 5 minutes in the middle. I have it set up right now so that it unlocks right away in the first 5 minutes, and asks for the pattern after that. Is this even possible?
|
I was able to set up what you want with one caveat: You have to use a PIN or a password, not a pattern. My solution depends on the apps Tasker (trial version here) and Secure Settings. Secure Settings requires root for some of its features. I don't know if this is one of them. If you aren't rooted, you can try it and see if it works. Posting a complete how-to on Tasker is beyond the scope of my answer. Instead, here's the official documentation and links to user-created guides. My solution involves setting up two Tasker profiles. The first one sets the PIN or password after a timeout. The second one clears the PIN/password once the screen is unlocked. Here are my profiles: <code> Profile: Screen Locked (98) Event: Display Off Enter: Anon (106) A1: Wait [ MS:0 Seconds:0 Minutes:5 Hours:0 Days:0 ] A2: If [ %SCREEN ~ off ] A3: Secure Settings [ Configuration:Set Pin Package:com.intangibleobject.securesettings.plugin Name:Secure Settings ] A4: End If Profile: Screen Unlocked (107) Event: Display Unlocked Enter: Anon (108) A1: Secure Settings [ Configuration:Clear Password Package:com.intangibleobject.securesettings.plugin Name:Secure Settings ] </code> Once you've got Tasker configured, go to your phone settings and set slide unlock (and set he timeout to be whatever you find to be an appropriate amount of time for the slide lock to come up) . Note that when the password/PIN is enabled, you'll first have to slide unlock, and then enter your PIN/password.

What does "zipalign" mean and what is its significance? When a ROM claims to be "zipaligned" what does that mean and what the difference from a ROM that is not "zipaligned"?
|
This mechanism is described at the Android developers site as follows: zipalign is an archive alignment tool that provides important optimization to Android application (.apk) files. The purpose is to ensure that all uncompressed data starts with a particular alignment relative to the start of the file. Specifically, it causes all uncompressed data within the .apk, such as images or raw files, to be aligned on 4-byte boundaries. This allows all portions to be accessed directly with mmap() even if they contain binary data with alignment restrictions. The benefit is a reduction in the amount of RAM consumed when running the application. In short: <code> .apk </code> content can be easier/faster/more optimal accessed due to the order of data inside the packed file. For deeper information, there's a "complete guide" available at AddictiveTips: What Is Zipalign In Android And How To Make Apps Zipaligned, which answers the second part of your question: Quite understandably, situation would be reserved for unaligned application packages. Resource reading would be slow and memory usage would be on the higher end of the spectrum. It would also depend on how many unaligned applications are present. For example, if less number of applications with an unaligned home application, you’d see slower application launch times. This is the best case scenario. For a worst case scenario, having a number of unaligned applications will result in the system repeatedly starting and killing processes, struggling with lags and huge battery drain.

I have a somewhat fancy tv that supports an external wi-fi module. If you connect that to the tv, you'll be able to stream media from a pc or other compatible device. At which point I thought, is there a way to consume that stream with an Android device? I have searched google play, there's a fair amount of tv apps that are just shortcuts to some online tv websites. I don't want that, the idea is to watch exactly what I have on my tv, turning my phone into a portable tv. What I imagine is a server box connected to the tv cable that streams it over WiFi, and then there's an app on my phone that consumes the stream. I understand that may involve a combination of software and hardware that would need to be purchased. Happy with that, just can't figure what it would be. Have done my Google homework to no avail. Please advice if there's a solution for that, or whether it's feasible at all.

It sounds as though you are using your TV as a media renderer for a media server (hosted on your PC or other computer device). If that is the case, then yes, it is possible to use your android device as a media renderer for a media server. Download MediaHouse UPnP / DLNA Browser and a video player with a codec that supports your video file-types ( VPlayer Video Player is the best that I've found). If you instead meant that you wanted to stream the content provided to you from your TV service provider, then that is a bit more complicated. Generally, they do not allow this since they want you to pay some odd sum of money for an additional renderer that they own. The process would go soemthing like this (if not otherwise allowed): Use some kind of capturing device to record (temporarily or permenently) the video content transmitted through an appropriate cable (HDMI for example). You would theoretically need to split the signal or re-route it. Then configure a media server on your PC to stream the recorded content. This would not provide a stream however which would have to be in a protocol like MJPEG to work as an actual "stream". You would need something akin to an ethernet based capture card that provided a video stream over IP.

My son has an Android phone, and when he bought it the storage space was divided thus: System Memory: 157MB Internal Memory: 1024MB When this was essentially full we put in an SD card to give him more storage. So now we also have SD card: 1.84GB When he fires up something called "App Manager" and clicks on "storage" he sees these three possibilities -- System memory, Internal memory and SD card. OK now here's the problem. If he downloads an app from the app store, by default it will typically install onto the Internal memory. He wants to put it on the SD card, but the only option available when he tries to move it with his app manager is "Move to phone". If he moves an app to the phone, which presumably is the system memory, then the only option now available is "move to internal memory". Furthermore, try as we might we cannot move any app onto the SD card. Is this expected behaviour? Is there a way of installing apps on his SD card (without rooting the phone, ideally)? The phone is an LG-E400, running Android version 2.3.6 .

System memory, internal memory is a mis-leading thing, its actually referring to storage space which is a very different thing to the meaning RAM often referred as memory! The reference to storage - system as in <code> /system </code> would be more accurate. When you download an app from the Play Store, it must be installed into the <code> /data </code> . From there you can actually move the app to the sd-card. On stock vanilla android, the option is there ' Move to SD card '. Now by the sound of it, its as if it is indeed moving the app to the SDCard, but its not really a SDCard, its how an internal storage space (think of USB flash drives), is treated as an <code> /sdcard </code> but in reality, you have internal and external storage, the latter being the actual micro SD card slotted in place. Its a bit confusing how it works, from a developer's perspective, when a check is carried out for an SD card, Android seemingly "tells" the developer that the internal storage is treated as an <code> /sdcard </code> . Also, to compound confusion even more, there's also a symbolic link to the real sdcard, <code> /external/sdcard </code> as well - this bit is dependent on what device/manufacturer is in question. Yes, this is the expected behaviour, whichever storage (from a view point of Android and the hardware device's file-system priority, is treated as "sdcard"). In short, nothing you can do, apart from using App 2 SD, but then again, that could fall into the same trap as I mentioned previously about the developer's perspective. Edit After the OP has edited their question to include the device, after looking at GSMArena <code> MEMORY Card slot microSD, up to 32GB Internal 1 GB storage, 384 MB RAM </code> Yup, it looks definitely like as if the internal storage is treated in this fashion as an "SDCard"... The naming is misleading. What is really meant, is: internal (phone) storage 157MB, internal SD-Card (eMMC) 1024MB

Just wondering, because I've just set my phone up to forward wifi traffic through my DD-WRT router. But I've no way to verify if my 3G traffic is also going through my router. Does anyone know if 3G traffic also goes through the vpn by default (if vpn is properly configured on the phone of course).

Yes, 3G traffic will go through your VPN if it's set up correctly. Whether or not your service provider supports that is another matter; some block VPN traffic (such as Verizon - see this thread).

I have downloaded so many custom ROMs to try, but I did not organize them. One of the zip files is called "ODEXED.zip". Is there any way to determine what it's name is just by inspecting the files in the zip file? Or maybe some other information about it? This is just curiosity, I know I can just flash it and see its info in "Settings> About Phone".
|
Ok. I have found the answer, at least for that ROM: In the <code> /system/build.prop </code> file in the zip file, the first "section" has build properties, which details all the information that is visible in the "About Phone" part. This is an example of it here: <code> # begin build properties # autogenerated by buildinfo.sh ro.build.id=GINGERBREAD ro.build.display.id=Hyper_Droid ro.build.version.incremental=DDKT3 ro.build.version.sdk=10 ro.build.version.codename=REL ro.build.version.release=2.3.6 ro.build.date=Wed Feb 1 15:11:04 KST 2012 ro.build.date.utc=1328076664 [...] ro.product.brand=samsung ro.product.model=GT-S5670 ro.product.name=GT-S5670 ro.product.device=GT-S5670 ro.product.board=GT-S5670 ro.modversion= v2.0 ro.author.name= Wilfred [...] # end build properties # # system.prop for GT-S5670 # </code>

I would like to be able to set up a silent period (at night for sleeping) where email alerts - but ONLY email alerts - will be silenced. I still would like to have text messages and phone rings be normal. Is there any way to do this automatically, without needing to go into the email app every night and turn off notifications and then remember to turn them back on in the morning?
|
If you do not depend on a data connection, there may be some solutions around: The Google Playstore has a lot of automation apps to offer, which you can use to set up more than this. In your case, this would be a time-based scenario: From 11pm to 7am, disable WiFi and mobile data No data connection => no new mail => no new mail notifications. Apps capable of things like that include e.g. Timeriffic (free, and one of the top-apps in this section), Llama (also capable of location-based and other rules), and -- my favorite -- Tasker. Though the latter is not the cheapest one, it is the most flexible, and you can get a 7-day-trial at their homepage. For examples what else you can achieve with Tasker , you might also want to take a look at <a href="stackexchange-url What is Cell standby and how can I keep it from eating my battery? , and the examples at the mentioned homepage. Also, a Google search on Tasker profiles will list you a lot of goodies. To accomplish your goal using Tasker , simply create the following profile: Context: Time (fill in your "from" and "to" to define the time frame) Task: Net-> Mobile Data: Set Off Net-> WiFi: Set Off That's all. Say you defined it as described above (11pm to 7am), Tasker would switch off WiFi and Mobile Data at 11pm, and return to the previous state at 7am. More solutions can probably be found here: stackexchange-url ("Is it possible to only silence certain notifications?")

I'm considering unlocking the bootloader on my Verizon Galaxy S3 (SCH-I535). However, a guide I was reading made this statement: Once you have unlocked your phone’s bootloader using this app, you must not receive any over-the-air (OTA) updates or via Samsung Kies. Doing so will result in bricking your phone. I understand that bricking a phone means rendering it unusable, but does this also mean unrecoverable? When a phone is "bricked", does that mean it is virtually impossible to restore it to a working state? I'm a little concerned about the risk if that is the case.
|
The term "brick" usually refers to the stone, which means: "device can only be used as paper-weight". Taken literally, there's no way to "unbrick". However, you also find terms like "hard-brick" and "soft-brick" used, which makes the term "brick" less absolute: A soft-brick is something you easily can recover from (count it as a "temporary paper-weight"), mostly by software-based solutions (e.g. re-flash your phone) -- while a "hard-brick" is rather meant in the way the original term points to. Still, technically spoken, even a "hard-bricked" device could be "unbricked" -- but mostly this is more expensive then getting a new device. As for the warranty declaration you quoted: For a normal user, it's almost impossible to (hard-) brick his device. Even when flashing a custom ROM, this can rarely happen, as there are many security-layers involved. Almost always you can boot your device into some fall-back mode where it is at least recognized by some "flashing software", so you could simply flash another/the original firmware back. Which means, the risk you are taking is to "soft-brick" your device 1 . A "hard-brick" is quite unlikely with "normal operations" like rooting or flashing custom ROMs. See also: Wikipedia: Brick RootzWiki: Brick 1 I just learned: "Unless you've got a Samsung device and used the software recommended by Samsung". So better don't use Kies etc., but rather Odin, just to give an example.

Power ON WOL enabled BIOS: In order to power up the remote host, you first have to enable WOL in his bios. The way you have to do this will vary from motherboard to motherboard, sou you'll have to figure it out by your self, or ask Google for some help. Remote Host cable connected to router Application capable of Sending Magic Packets to Remote.host's MacAdress At the moment I'm using WOLdroid WOL Wake On Lan On remote.host execute: <code> ifconfig </code> Detect your remote.host's ehternet board usualy eth0 and save the HW Adress value XX:XX:XX:XX:XX:XX:XX Enter that number when WOLdroid asks you for a mac adress. And your done. Now you're able to powerup remotely Power OFF 1. Prepare the Remote Host: Remote host with Ubuntu 12.04 Create your private and public key files To follow these steps you'll have to access your remote host, physically, or using another computer. I'll describe this as if you have physical access to the remote.host Open a command window and install the ssh protocol: <code> sudo apt-get install ssh </code> Create public and private keys using ssh-key-gen <code> ssh-keygen </code> You should save the generated key in: <code> /home/yourusername/.ssh/id_rsa </code> Press enter twice to leave the passphrase empty. <code> Your identification has been saved in /home/yourusername/.ssh/id_rsa. Your public key has been saved in /home/yourusername/.ssh/id_rsa.pub. The key fingerprint is: XX:XX:XX:xX:XX:xX:XX:XX:XX:XX:XX:XX:XX:XX yourusername@remote-host </code> Now copy the id_rsa.pub to your ~/.ssh/authorized_keys file with this command: <code> ssh-copy-id -i ~/.ssh/id_rsa.pub remote.host </code> Now you have to be able to execute the sudo shutdown -P 0 with no password . Modify /etc/sudoers on remote.host with visudo That way user " yourusername " can execute the shutdown command with no password asked. Run: <code> sudo visudo </code> By running visudo, it leads to edit /etc/sudoers. Add the line below to that file. <code> yourusername ALL = NOPASSWD: /sbin/shutdown </code> Now we are able to access remotely, and shutdown without passwords asked. 2. Prepare your Android Connect your android to the remote host and with your file explorer copy the id_rsa file located in ~/.ssh/ folder to the Android's SD card. Disconnect your android from the remote host Install a ssh client program. (ex. ConnectBot ) Open Connect Bot and go to Manage Pubkeys > Import and select the key you copied later. Go back to Connect Bot's Main Scren and select the ssh protocol from the list and enter <code> [email protected] </code> . Notice that it creates a line in the main screen with the data you input. Push it for a couple of seconds and select edit host. Select <code> Use pubkey authentication </code> and select <code> id_rsa </code> On <code> Post-login automation </code> write <code> sudo shutdown -P 0 </code> Go back to you the Main Screen of Connect Bot and we're done! Now you can Turn on and Shutdown a remote.host :)

You will find a good explanation including graphics to visualize what's going on in the article The Android boot process from power on. Basically, the steps are as follows: execute Boot ROM code. This is stored in a hardware-specific area and keeps information on where to find the first stage of the boot loader, which is then loaded into RAM. You can compare the Boot TOM with the BIOS in your desktop PC. execute first stage of the boot loader. On desktop computers, this can be compared with the boot menu, e.g. Grub/LiLo on Linux. It sets up some basic stuff, and then turns control to the... Linux kernel, which will, together with the init process, initialize the base system, e.g. caches, file systems, etc., and then calls... Zygote, which initializes the Dalvik VM, and then starts the... System server. Now we are in the Android-system, and set up all Android-specific services, like e.g. telephony manager and bluetooth. Finally comes: Boot completed -- this event will be broadcast, so apps having registered listeners on this will be started. To help you visualize this, here's the last image from the mentioned site:

Sometimes it's desirable to use a device on a carrier that does not officially sell it. Often this is due to regional differences and travel (for example, using a US phone in Europe) but also because some carriers simply do not offer phones that other carriers do. How can I determine if it's possible to use my phone on a different carrier, and which carriers it is compatible with? This community wiki is intended to be a canonical answer to a common question. If you feel that improvements could be made then please edit the post(s).
|
Whether or not you can use a phone on a specific carrier depends on a variety of factors, but it is generally possible to figure it out provided that you can find enough information on the device and carrier you are interested in. The main points to focus on will be the cellular standard the carrier uses, the frequency bands it uses, and the associated bands/tech that the phone is designed for. In order for your device to operate fully on another network, it will need to meet all of the following criteria. Cellular Standards There are two primary competing cellular standards used throughout the world, commonly referred to as GSM and CDMA. GSM (Global System for Mobile Communications) is generally the more widely deployed of the two standards, and is estimated to serve nearly 80% of the global market. Devices that support the GSM standard will use SIM cards to keep track of the identity of the subscriber. The 3G standards used by GSM devices are typically UMTS or HSPA . CDMA (or, more specifically, CDMA2000 ) is also used in a variety of countries, but generally serves fewer subscribers than GSM in most countries. CDMA uses a R-UIM / CSIM card which serves similar functionality to SIM card. On some carriers, CDMA devices do not use any physical identity cards, and instead have an ESN that is stored on the device itself. Also with some carriers, devices that normally do not require SIM card to operate on CDMA 3G may require SIM cards for 4G access, since the 4G network uses a different technology than the 3G one. In general, a device is therefore classified by which network it uses for it's 3G or voice coverage, so a phone which supports CDMA voice/3G but a GSM 4G network (for example, the Verizon Galaxy Nexus) would still typically be considered a "CDMA phone". These two network standards are not compatible with each other in any way. A device built for GSM networks will not work on a CDMA network (and vice versa). Therefore, the first step in determining if your device will work on your desired carrier is to determine what networks it supports and what type of network the carrier uses. GSM Arena is a good source for device specifications, and Wikipedia is a good place to find information about carrier networks (as well as devices). In addition to the inter-network compatibility issue, CDMA devices that do not have physical a identity card can only be used with the device's original carrier or on other countries through roaming. In most cases, carriers have a large database that contains all of the valid ESNs for their network, so only models which are sold by the carrier can be activated. This can occasionally be bypassed by altering the software of the phone to broadcast a different ESN, but doing so is illegal in many countries, and thus there is often no legitimate way to use a CDMA device on a different carrier. This restriction will usually (but may not always) also apply to virtual network operators ( MVNOs ) and their "parent" carriers. As an example: Sprint may not allow you to activate a Boost Mobile phone on its network, even though Boost uses Sprint's towers and spectrum. Conversely, Sprint has approved some of their phone models for activation on certain MVNOs that use Sprint's spectrum (provided the phone is not under contract). Therefore, when dealing with CDMA carriers, your best choice will generally be to simply ask them if your model will be allowed on their network before you make a decision, since they have full discretion over which devices they will allow to be activated. Frequency Bands Each carrier operates their network on a specific set of frequency bands, which are typically managed at some level by the government of the country the carrier is operating in. Once the government allocates frequencies, they can usually be bought or sold by companies as they see fit (with some restrictions). In order for a device to work on a given network, it must therefore support not only the network standards (as noted above) but also the frequency bands being used. As an example, AT&T's 3G network (UMTS/HSPA) operates in the 850 and 1900 MHz frequency bands ( source ). The myTouch 4G , sold by T-Mobile USA is a GSM phone (T-Mobile USA is a GSM network), but it is designed for the 900, 1700, and 2100 MHz frequency bands since this is what T-Mobile uses. Therefore, a myTouch 4G would not be able to use AT&T's 3G network because it does not support the proper frequencies. Further, there is no way to alter this by using software modifications - the limitation is created by the phone's antenna , which is specifically designed to pick up certain frequencies and ignore others. Using the same example as above, however, you can see that AT&T operates its 2G network on the 850 and 1900 MHz bands and the myTouch 4G supports 850, 900, 1800 and 1900 MHz for 2G operation. This means that a myTouch 4G would be able to use AT&T's slower 2G network (and make voice calls) even though it cannot use the 3G network. Similarly, it may be possible for a device to operate on a carrier's 3G network but not their 4G network due to frequency differences. Check the frequency bands your device supports for each generation of network communication (2G, 3G, 4G) in order to ensure complete compatibility. SIM Locks and SIM Cards Another possible hurdle in running a device on a network it was not officially intended for is SIM locks and differences in SIM cards. Firstly, many carriers will sell their devices with a SIM lock - a software restriction that prevents the device from operating with a SIM from a different carrier. In many cases this will depend on whether or not the device is purchased at a subsidized price on some kind of annual contract. Purchasing a device at full retail price will often allow it to be unlocked more easily (or it will be provided in an unlocked state). If your device has a SIM lock, it may be possible to unlock it by contacting your carrier and asking for an unlock code. There are also third-parties that offer SIM unlocking services, but they are not officially endorsed by the carrier or manufacturer of your device. Devices will only be able to operate on their originally intended network while they are SIM locked. An additional concern is that there are several types of SIM cards , all of different shapes and sizes. Most major carriers (and, indeed, even smaller ones) will be able to provide multiple types of SIM cards, but be sure that you get one that will fit into the slot on your device. Most commonly, phones and tablets use either Mini-SIM or Micro-SIM cards. What about rooting? stackexchange-url ("Rooting") a device is not related to the act of unlocking it for a different carrier, although the phrase "unlocking" my occasionally (incorrectly) be used to refer to both processes. Obtaining root will not unlock your device, and unrooted devices are capable of being unlocked provided with the proper SIM code. Similarly, a custom ROM will not unlock your device - it has no bearing on the SIM lock.

I have a non-rooted Verizon Samsung Galaxy Nexus, and I wanted to try the "adb backup" feature. Possibly in preparation for rooting, but that's not really relevant to the question. I want to back up everything . I used this command on a Windows 7 command line: <code> adb backup -apk -shared -all -f c:\mybackup.ab </code> My phone prompted me for my password, which I entered, and clicked the button to begin the backup. I let it run for several minutes, and the cmd window returned to C: prompt. On the phone, it was still flipping through filenames. At some point, it stopped flipping through filenames but the back up selection buttons were still greyed out. C:\mybackup.ab existed, and was about 1GB in size, which is significantly smaller than I thought it should be, especially since I said to back up the apk files and the whole "shared" space (/mnt/sdcard). What should I see (on the PC and on the phone) when the backup process completes? How long should I wait, if I estimate I'm using about 10GB of the 32GB of space? Edit: ... and/or is that the wrong set of command line arguments?
|
The <code> adb backup </code> command won't work fully on an unrooted device as it will attempt to backup things like the <code> /system </code> partition, and without root access the phone will deny you this for safety reasons. I'm glad to hear running it with the <code> -nosystem </code> flag worked out for you :) If you want to do a complete backup you need to be rooted. The <code> /system </code> partition, according to this page: contains the entire operating system, other than the kernel and the ramdisk. This includes the Android user interface as well as all the system applications that come pre-installed on the device. Wiping this partition will remove Android from the device without rendering it unbootable, and you will still be able to put the phone into recovery or bootloader mode to install a new ROM. This means that your backup does not include anything related to your operating system, only your apps and their settings. If you decide to root your device, you can create a very solid backup from CWM Recovery where all partitions are backed up to the sdcard on the device, including the system and boot partitions.

I'm Thinking about a Queue management system built with Android tablets. I figured out that the cheapest way to give each customer a number is a thermal receipt printer. I'm looking for any solution that: Can print text and basic graphics (e.g. QR codes) Can connect to my Android directly via BT or USB, without Cloud printing or internet connection Is generally reliable, and can handle a few hundreds of prints every day Is thermal printing a good idea? Are there any thermal printers that play nicely with Android?
|
What you are looking for is usually known as a 'receipt printer'. A quick Google for 'bluetooth receipt printer' turns up a number of models from a variety of manufacturers (quite a few of them are actually battery powered and portable - like you see at car rental places). The big problem here is that Android doesn't really have any concept of local printing, so I think you're going to have to implement it yourself. Android DOES have bluetooth communications APIs (docs), and I'd be surprised if the printer manufacturers haven't heard all this before, and have at least clues how to proceed (after all, they like to sell printers!). If you'll be buying a significant number of printers, I bet they'll happily help you talk to their devices. If that's too expensive for you (and those printers look a bit pricey), then you could try USB. Again, you can find USB receipt printers, which again you'll have to learn to talk to. Android does have a set of USB APIs (docs). On the plus side, my quick Google for 'USB receipt printer' turned up some sub-$75 choices right away, so this might be a good approach if you are price sensitive. I'd also be willing to bet that at least some of the USB printers are actually serial devices with something like an FTDI chip bolted up to them. That means that talking to them is probably not very difficult. Alternately, if you can find a cheap receipt printer that's serial or something, you could look at the IOIO boards and software stack as a way to interface your android tablet to some funky printer. These are boards that adhere to the relevant Android APIs + software that makes them easy to talk to. The boards are available commercially, and the schematics are available, if you want to build your own, and they are designed to make hardware interfacing easy.

The limit is actually placed on virtual size of the downloaded area. The upper limit is approximately 80MB of data, and the lower limit is smaller than maps displays, somewhere below 100KB, equivalent to around .6 square miles. Here is one place that mentions the 80MB limit. In my own testing, I was able to download up to 87MB of data, which is approximately 5625 square miles. This may have been coincidence, but in my testing, the allowable size ranged from a square .75 miles on a side to a square 75 miles on a side.

Some vendors set up their phones to reinstall system applications at boot in case they go missing. Try finding a directory that contains a copy of the APK that's used to reinstall it, and delete it from there. A simple alternative solution is to freeze the unwanted apps rather than uninstalling them. Titanium Backup and Link2SD can help you with that (both require root). In ICS+, there's also a user-accessible mechanism to deactivate apps from the settings menu.

Hopefully, the title says it all. I know some app developers say that I should uninstall then reinstall their app if experiencing problems or updating, but I wondered if stopping the app and clearing data via the Manage Applications setting would accomplish the same purpose. I'm running ICS 4.0.3.
|
Answer is no, you're not uninstalling the app by clearing the App data. Clearing the application data is more or less resetting the application to an initial state before being customized based on the application settings, such as preferences, databases. I am aware it sounds contradictory but the crucial element in this is - the dalvik cache has the pre-cached dex class within the Dalvik VM for the said app.

After a year using my phone, I noticed the battery drains too fast, but after shutting down I manage to make it work again for a couple of minutes before it shuts down automatically. I read that to recalibrate the battery, you should fully charge it and by various means delete the batterystats.bin file. (examples with clockworkmod or using an app ) The thing is... "When you follow the steps to recalibrate your battery and delete the batterystats.bin file from your phone, you are getting rid of more than what you think… Stored inside that batterystats.bin file, your phone keeps detailed logs of the capacity of your battery and uses it on how it can be utilized more efficiently." Read Full or oppositely, quoting Dianne Hackborn "It (refering batterystats.bin) has no impact on your battery life." I know it's not possible to make it as good as new, but at least reset it in a way it would read that last bit of energy accurately?
|
Android shuts down your OS before it actually becomes completely flat, in order to ensure it has enough power to do so safely and completely (which is why you can power it back up again, but then it shuts itself off again). Over time, your battery does need to be recalibrated as the system stats on battery usage get wonky and the battery itself won't store as much of a charge as it could. For most phones, the proper procedure is: Let the phone run until it shuts itself off. Without turning the phone on, plug it in and let it fully charge up. Unplug, turn the phone on and let it run flat again. Battery and battery stats are now recalibrated. Deleting batterystats.bin isn't generally necessary. You should find your battery lasting much longer now (I know this works well on my Samsung SK4G - I go from not being able to last the day to being able to last a full day and night) If memory serves, one is supposed to recalibrate one's battery like this every 30-90 days.

Please help me to emulate my Phone's SD card as a network drive in my Wi-Fi network. I am able to mount it as a Media device which will only help us to play music with Windows Media Player. But I want my SD card as a network drive.
|
A good application to do that is the Samba Filesharing. It shares your sdcard, making it easy to transfer files from/to your phone. Settings After installing the application from Google Play, open it and fill a password by touching the password menu. The default username is SDCARD and the default Workgroup is WORKGROUP . You can leave it that way or change it in a way that suits you. I'd recommend enabling and selecting your WiFi in the WiFi White List . That way it only enables Samba sharing when connected to your preferred Network. That done, you only have to go to your Network Shares and look for a device called ANDROID . Login Name: SDCARD pw: (the one you defined earlier) Open the shared folder and it will ask again for credentials, and you're done. Here you have a video that completes this information.

I'm thinking about getting a new sd card and read that the class of them really matters. I'm looking at getting a 16gb one with a class not less than class 6. How do I check for the class?
|
An SD Card class basically the minimum sequential write speed that the SD card supports. Testing the class of an SD is quite easy, just copy a 1 GB file to an empty card and measure the time it took for the copy. A class 6 SD card should support at minimum 6MB/s. Also check out the markings on the SD card, there should a logo like the following: the number in the logo describes the speed class.

I have upgraded to the latest official version available through Kies. And I have noticed that after the update the vibrator of the phone is not working. Actually its working but not in Silent mode on receiving a call. When we switch to vibrating mode or at the boot-up the phone, the vibrator vibrates. So the vibrator is functional. I have searched a lot and I could not find any valid solutions.
|
Go to Settings -> Sound and make sure Silent mode is set to Vibrate , then in <code> RINGTONE & NOTIFICATIONS </code> section, check the option Vibrate on ring , then call yourself and it should vibrate.

Can any one explain me where save android's music player playlist files? actually, I got problem when i format my SD Card after that no playlist in music player. I am using samsung galaxy 551 with Android 2.2 froyo.
|
You can place .m3u files anywhere on sdcard which is under reach of media scanner. Playlist will be displayed in music player once media scanner will complete scanning sdcard. Path of system-created playlists (playlists are common to all music players): <code> /data/data/com.android.providers.media/databases/external-xxxxxxx.db </code> where xxxxxxxx are random numbers. Path can be slightly different based on Android versions & devices. If you want to backup your playlists, i'd recommend you to use Titanium Backup .

I'm researching which phone to buy next and have mostly decided on a Samsung Galaxy S3. I'm on T-Mobile in the UK, which will probably transition to everything-everywhere in short order, who are launching a 4G service. I'd like to get the US variant of the phone because it is built with 2Gb of RAM and a 1.5GHz processor, as compared to the UK's 1Gb of RAM and a 1.4GHz processor. I've read that the carrier frequencies for US 4G/LTE are different from the UK's. Is that true? If it's true, can the US variant be persuaded to work in the UK, 4G-wise? I'm not shy of flashing custom ROMs and so forth. (I'm assuming that it will work without issue on 3G?)
|
Is that true? Yes, this is true. The USA is currently using the 700, 800 (Sprint only, I think), 1700 and 1900 MHz bands for LTE service, whereas European providers are using 800, 900, 1800, and 2600 MHz ( Wikipedia ). If it's true, can the US variant be persuaded to work in the UK, 4G-wise? I'm not shy of flashing custom ROMs and so forth. No. The frequency limitation is not set by the software - it's the antenna. Flashing custom ROMs will not allow you to access frequencies that the antenna is physically unable to support, so there's nothing you can do short of modifying the hardware. I'm assuming that it will work without issue on 3G? This could potentially depend slightly on which specific variant you want, I suppose. The AT&T one supports 850, 1900, and 2100 MHz frequencies, the T-Mobile USA one also supports 1700 on top of the other three. According to this table , T-Mobile UK uses the 2100 MHz band, so either should be compatible with their 3G service in that case.

I use the hotspot feature on my HTC One X alot for connecting to the internet with my laptop. It's worked fine for months, but all of a sudden the last two days, the hotspot just stops for no reason that I can discern. I have restarted my phone and haven't installed any news apps recently. Any ideas?
|
You most likely have a hotspot timeout setting enabled. You can disable it by going to your Advanced Hotspot Settings, and editing the timeout value to never. Note that in some versions of Android in order to access the Advanced Hotspot Settings you need to first access the WiFi Hotspot Settings and then press the phone's Menu button.

Initially I thought this was a problem with Google Play / Apollo, but I realize now that when I plug in my phone via USB, I can't see any of the many, many folders and files present on <code> /sdcard </code> that I could see previously. If I copy a "new" mp3 onto my Galaxy Nexus, it's recognized just fine by both Google Play and Apollo. However, none of my old mp3s are recognized. They were placed in <code> /sdcard/Music </code> , a folder that I cannot see when I plug in my phone, only from the file manager running on the phone. The issue persists if I move an "old" mp3 from my music folder out into the sdcard root, it's still not recognized. This makes me think this might be permission related, but the file manager says that all files are readable and writable. I've tried running "fix permissions" in both ROM manager and the CWM recovery, but it makes no difference. Any idea what has happened, and how to fix it so that I can use all my old files again? :) edit If it's any help, I just ran <code> ls -al </code> in a terminal emulator and I can't see any difference at all between folders I can and cannot see. Example: I can see <code> /sdcard/media </code> just fine, because I created that folder from Explorer in Windows. Music in that directory works. I cannot see <code> /sdcard/music </code> . Here's the permissions: <code> drwxrwxr-x root sdcard_rw 2012-09-18 media drwxrwxr-x root sdcard_rw 2012-09-16 music </code> This is a bit confusing. edit2 When I try pulling and pushing a file with adb like so: <code> adb pull file.tar adb push file.tar file2.tar </code> I get <code> failed to copy 'file.tar' to 'file2.tar': Read-only file system </code> As bk201doesntexist on the XDA forums pointed out, this is because you have to use an absolute path. However, when I do <code> adb push file.tar /sdcard/file.tar </code> the file gets transferred, shows up when i run <code> ls </code> , but it's invisible in the "Galaxy Nexus" unit in My Computer in Windows. tl;dr When I push files with <code> adb push </code> they get transferred but don't show up in the "Galaxy Nexus" unit in My Computer. "Old" files from before ROM-switching do not show up. New files that I put in now work fine.
|
As a final resort, I tried doing a full wipe and reinstalling CM10 M1 completely, without restoring any settings or apps from any old installations. The issue still persists! Any files created with my now "old" CM10 installation no longer appear, even when they are moved within a folder where other "new" files are shown and working. Switching back to AOKP also did not solve the issue, so the issue does not only persist over reinstalls of CM but also across ROMs. What finally solved this issue for me was reformatting my <code> /sdcard </code> partition with the newest version of CWM Recovery. This might not be a very clean solution, but in my case I needed to clean up the sdcard anyway. If formatting isn't an option, try the other answer posted here regarding <code> .nomedia </code> files, I had no success with it as I was unable to find those files.

I use Cyanogenmod profiles (on a Galaxy S2). I've created a couple of custom profiles, "Silent" and "Totally Silent", and I switch to them by doing a long press on the power button. But I've noticed something disturbing: At the bottom of the dialog, there are 3 icons: A speaker with a cross over it, a vibrating phone, and a speaker. These look suspiciously like my profiles. When I switch to "Totally Silent", the icon gets switched to a vibrating phone. But when I switch back to default, it doesn't switch back to the speaker! What's going on? Are there 2 separate profile selections? I want to have just one place where I set the profile, not two.
|
Profiles are just a way to change a bunch of settings at once. By long-pressing the power button and tapping ring/vibrate/silent (below airplane mode) you change a single setting however: The ringing behaviour. The profiles work slightly different to what you expect. You most probably forgot to enable some switches of the standard profile, most of them are on/off settings for which a profile has 3 actions: activate deactivate modify / do-not-modify This is for example very handy for a car mode that you activate to just switch off a security lock screen (+ enable GPS and leave all else as is). The standard profile has a lot of those unset do-not-modify checkboxes (the checkboxes to the right), so unless you check them the profile doesn't actually change those settings. Tick the checkbox and try again!

Okay, I did a brief test the other day... only drove about 80 miles, ... obviously longer drives would give better averaging samples. But from my short drive, it seems that Maps navigation uses roughly 1 MB for every 10 miles.

I've put a custom ROM on my Samsung Galaxy S I9000 and now I want to go back to my original ROM. I was wondering if there was a way to get the original ROM, that came with my device, from an official site somewhere. I've searched this websites and other forums but the links were old and not valid anymore.
|
In a way, the answer is Yes. Although, I would not consider any of the sites where you would get the ROM from to be "official". What you need to do is download ODIN3 (or hemidal) and use that tool to flash the Stock ROM on the device. Doing so will most likely require you to completely wipe the device to factory state. I found a couple sites that do have the Stock Firmware, but I don't want to link to the ROM directly for a couple reasons. One, I don't know the legality of linking to a the Stock Firmware and if the file is no longer valid in the future, I do not want this post to be "out of date". If you google "flash i9000 odin stock" you will likely find a couple different sources that have the files needed to flash back stock. When I did this, the first site had the 2.3 XXJVU release for the i9000, and the .pit file (which is also required when going back to stock, and the drivers. It also is a tutorial on how to flash it.

I got mine from Google Play Store from one of my friends coming from US. And it works just like that. There are no hardware / software shortcomings at least as of till now except for being not able to access Play Store, Play Music and other geo-location specific apps. I got upgraded to Jellybean as well almost immediately. Just in case, if its useful, I am with Airtel. If you buy it from stackexchange-url ("Amazon"), its costlier at least by $60. I would suggest order it from Google Play. And ask one of your friends to pick it up.

these can only be removed if you root your device. And even then, some of them you would not want to remove as they tie in to the system. Additionally, removing them will not free usable space for "non-system" apps. The /system is separate from where user apps are installed and the space is separate.

Apple just launched the iPhone 5; together with that they landed new earphones they call 'EarPods'. I have an HTC Desire HD Android-based phone. It has a 3,5mm jack just as the iPhone. Would the earphones and microphone of the EarPods work on my phone as well? Having good quality earbuds that stick in my ear sounds attractive to me. I do not care about the controls per se, and I'm pretty sure the sound will also work, but I'm not sure about the microphone. Also, how much of the improved sound and noise reduction is implemented in the software?
|
Firstly because they use the 3.5mm standard they will transmit sound to Android just as you would expect on the iPhone. All the controls work fine with the exception of the volume up and down. The microphone works currently on Android as well. Source: http://www.androidcentral.com/earpods-ear-holes-android

I have a Huawei u8160 running Cyanogenmod 7.2 . I have been looking for the fuse.ko module for my phone, but whenever I find anything ,terminal emulator tells me that it is incompatible! I want it to enable NTFS file system support using this tutorial So I was wondering where I can find the appropriate fuse.ko module? NOTE : I've already seen this link but I don't think that's what I want.
|
You can build that module yourself from the source code of the Linux kernel your device is running (presumably some Cyanogenmod kernel). You can find out which kernel your device is running, and with which compiler it was built, using <code> cat /proc/version </code> . Try finding the corresponding kernel sources in the Cyanogenmod repositories. The kernel configuration file used to build your kernel (.config) should come with the kernel sources. If you're lucky, you can dump it with <code> zcat /proc/config.gz </code> on your device. Put the .config file into your source tree. Find a matching compiler. Typically, one of the compilers coming with the NDK will be fine. If the kernel uses modversions, you first need to build the kernel to get the Module.symvers file right. Assuming the NDK's cross compiler is in your path, try: <code> make -j4 ARCH=arm CROSS_COMPILE=arm-linux-androideabi- </code> One you have a kernel, add the modules you need to the configuration by using the xconfig (or menuconfig) make targets: <code> make -j4 ARCH=arm CROSS_COMPILE=arm-linux-androideabi- xconfig </code> Build the module. <code> make -j4 ARCH=arm CROSS_COMPILE=arm-linux-androideabi- modules </code> If insmod'ing the module fails with an error saying that _GLOBAL_OFFSET_TABLE_ was not found, try adding the -fno-pic option: <code> make -j4 ARCH=arm CROSS_COMPILE=arm-linux-androideabi- XTRA_CFLAGS=-fno-pic modules </code> Good luck.

Battery on Samsung Galaxy S2 on ICS likes to drop after reboot. Actually it happened when I was on Gingerbread as well. Anyone can help me fix this? Screenshots:
|
There is no easy way in finding which process consumes your battery . The battery monitoring tool in Android is not active during boot, so anyone wanting to know what's happening will have to make deep hackings in the Linux kernel and Android init scripts. I don't even believe you have a rooted phone or have a Android AOSP sources snapshot somewhere to hack into. Also I believe that the battery estimation mechanism is somehow fooled at startup . Because it has no previous data to compare to (N is estimated depending on the value of N-1). So the level you see right after bootup is probably wrong. That's why you see the level strangely increasing although no power source was connected in the meantime. To what extent is this level wrong? Question without answer I think. I have an easy solution though: stop installing apps that make your Android crash or need (stupid) reboot :-)

Looking up my battery statistics, I almost always find Cell standby amongst the top consumers: I never thought that "idle" would use so much energy. I saw that other people encounter similar problems: stackexchange-url ("Cell standby and Phone idle") stackexchange-url ("Galaxy S3 cell standby is eating my battery") Answers on those questions just give some raw ideas. I would like to know what exactly stands behind this, an whether there are ways to keep this "standby" from eating my battery?
|
Cell Signal Some backgrounds as explained by stackexchange-url ("ce4") on the question stackexchange-url ("Does 'poor' reception deplete the battery quicker?"): The transceiver circuit is engineered with power saving in mind and will reduce sending power as much as possible if the reception is good. This also reduces the SAR value which is a measurement for exposure of the human body to radiation. If the reception is bad sending signal strength has to be adjusted accordingly. So that's what's really behind it: On poor reception, the device spends a lot of power to find a better/stronger signal (or any signal at all if lost). The following screenshot 1 clearly shows those times, when you take a look at the bar titled Phone signal . "The greener the cleaner": A bright green means "good reception" (the screenshot shows this at the begin and end, that is here: morning and evening -- so at home I have good reception). Getting yellowish: "Moderate reception". This uses more energy: compare it with the graph on top of it (not in the screenshot -- but the same as in the first screenshot), and you see the bar is almost flat where the cell signal is good -- but falls faster where it's not. See the little red spots: "no reception". And phone will power-up like crazy to find a new cell tower... How to find out where the dead spots are? I already showed in my answer on stackexchange-url ("Does 'poor' reception deplete the battery quicker?") how one can find out about those "Dead Zones" and where they are: Apps like No Signal Alert 2 and OpenSignalMaps 3 monitor the cell signal in background, and record those areas, so they can show you a map of where the dead zones were. OpenSignalMaps has the plus of showing you all cell towers in reach, pointing out which you are connected to. It also offers you a "compass" giving the direction to the strongest signal. However, my answer on how to automatically deal with those dead zones was not that detailed. So I played around a bit with different solutions -- and here's what I've found out: How to automatically deal with those dead zones to save energy? Apps to automatize Airplane Mode I've reached fairly good results with two apps: Autopilot 4 and NoBars Battery Saver 5 . Both monitor the cell signal and, when it drops to far, switch to Airplane Mode for a predefined time. The user can define how long that would be. After that timeout, Airplane Mode gets disabled, and cell monitoring takes over. In the second graph of my question, this shows up as "gaps" in the Phone Signal bar: As the cell radio was disabled during Airplane Mode, no colors are shown; the system didn't know anything about signal strength in this time frame. And with the cell radio turned off, it also didn't use additional power (more precisely, it didn't use any power for this radio then) -- which was exactly what was intended. With Autopilot , the only annoying side-effect was: For each signal check, it flashed on the display for about a second. Aside from that, it gives more options to be configured by the user. However, as the results of both apps where absolutely comparable, those extra options seem not really necessary, while being nice to have. Another plus of Autopilot is the log provided to the user: This way you can see the exact times of mode switches. Apps to handle data network I've also tested ShutUpBatterySaver 6 , which aims to handle the data traffic. Dropping below a certain signal strength the user can define, it disables AutoSync, and below a second definable level switches off mobile internet altogether. It does, however, never activate (or deactivate) Airplane Mode, so the power used to get a (better) signal will still be the same. Though, with a bad signal data transfer uses more power than with a good signal, as e.g. package loss might be bigger. In the status bar I saw several times that it had AutoSync disabled 7 , so it seems to work. Not being a heavy data user (as the LBE stats in the same screenshot show), I could however not really tell how much help that brought: Compared to the two Airplane-Mode handling apps above, results in terms of gained battery duration were minimal (if any). Combined solution It would probably gain best results to join the two approaches. As I was not in the mood to check all possible combinations, I rather decided for the allmighty 6-letter-solution: T-A-S-K-E-R. As most of you probably know, Tasker is the automation solution on Android. Guess it could even prepare coffee, if our devices had sensors to detect coffee and water. So I created some profiles for this great app -- and results were magnific! So basically it's 3 Profiles, communicating via a common variable: %SIGSTATE < 1: check if the signal falls below ~25%. If so, disable mobile data, set %SIGSTATE to 1. %SIGSTATE < 2: check if the signal falls below ~15%. If so, switch to airplane mode, set %SIGSTATE to 2. %SIGSTATE > 0: wait for 5 min, then disable airplane mode, activate mobile data, wait another 15 sec (for the signal to be restored), set %SIGSTATE to 0. In my global Init profile (which gets executed when Tasker starts monitoring), %SIGSTATE is set to 0 (if it is unset). All 3 above profiles additionally set notifications, as the screenshot above shows 9 . Each state maintains one notification (which gets replaced when the same state re-occurs), the most up-to-date state is always on the bottom. Results seemed even better than with the two airplane-mode handling apps above, but that might also be due to slightly different signal conditions. So it should at least be comparable. Using one of these 3 solutions, I came home after about 11 hours with about 20% more charge left then without applying any of them. Having said this, I will end this answer showing the Tasker profiles I created, so you might use them with your Tasker installation: Task "InitVars": Variable -> Variable Set: %SIGSTATE = 0 Task "SigLow": Net -> Mobile Data: Off Variable -> Variable Set: %SIGSTATE = 1 Alert -> Notify Vibrate: Title "IzzySignal"; Text: "Signal Low; Mobile data disabled (Signal: %CELLSIG)" Task "SigLost": Variable -> Variable Set: %WLANSTATE = 0 Variable -> Variable Set: %WLANSTATE = 1 IF %Wifi ~ on Net -> Airplane Mode: On Net -> Wifi: On IF %WLANSTATE ~ 1 Variable -> Variable Set: %SIGSTATE = 2 Alert -> Notify Vibrate: Title "IzzySignal", Text: "Signal Lost; Entering Airplane Mode" Task "SigReturn": Task -> Wait: 5 Minutes Net -> Airplane Mode: Off Task -> Wait: 15 Seconds (give the device some time to find a new signal!) Net -> Mobile Data: On IF %ROAM ~ Off (prevent bad surprise when returning from vacation abroad!) Variable -> Variable Set: %SIGSTATE = 0 Alert -> Notify Vibrate: Title "IzzySignal", Text "Signal On; Airplane Mode disabled (Signal: %CELLSIG)" Now for the profiles: Profil SigLowCheck: State -> Variable -> Variable Value: Name "%SIGSTATE", Op "Math: Less Than", Value "1" State -> Phone -> Signal Strength: From 0 To 2 State -> Tasker -> Profile Active: "SigLost", [x] Invert (make sure to avoid a conflict: %SIGSTATE~0 && SignalStrength~1 would match both profiles condition) Task: SigLow Profil SigLostCheck: State -> Variable -> Variable Value: Name "%SIGSTATE", Op "Math: Less Than", Value "2" State -> Phone -> Signal Strength: From 0 To 1 Task: SigLost Profile SigReturnCheck: State -> Variable -> Variable Value: Name "%SIGSTATE", Op "Math: Greater Than", Value "0" Task: SigReturn Profile Init: Event -> Tasker -> Monitor Start Task: InitVars Now that's just the basic concept, and can be extended with e.g. playing sounds, vibrating, flashing the display, and more. But the energy saving stuff is already in -- and does its job as described. Hope this can help you as well! Another remark: At least with GSM (I cannot tell for CDMA), returning from Airplane Mode by default forces you to enter the SIM PIN. This can of course be switched off -- but in that case this additional protection is also gone when switching on the phone. No idea why this is not possible selectively, as it was with my pre-Android phones. However, for some phones there's an alternative to some items in above tasks, which remove this limitation: In SigLost , instead of Net -> Airplane Mode: On use Phone -> Radio: Off if your phone supports this (my Droid2/Milestone2 does not, unfortunately). If you can do this, the WiFi check becomes obsolete (and your Task cleaner). The counter-reaction in SigReturn then also needs to be changed: Instead of Net -> Airplane Mode: Off , use Phone -> Radio: On . Please let me know in the comments if this removes the limitation of the SIM PIN, as I cannot test it (my device does not support it, as described above). Edit by t0mm13b The interesting thing I noticed was that there was multiple tasker icons appearing on the Status bar, which made things confusing as to regards the state that the tasker profiles was running as; I discovered that by setting the Title for the 'Notify Vibrate' in each of the above tasks to be the same, the net result is, one singular notification titled ' IzzyTasker ' shows up, with the appropriate message used instead.

I am curious about the way Android phones obtain the battery temperature. Android has an API called BatteryManager which provides the value of instant battery temperature, but is there an actual temperature sensor inside the battery? Or is this value purely calculated by a certain equation, using the value the current, the voltage and the elapsed time? If it is calculated not measured, is there anyway that we can know how hot the phone really is?

Every mobile battery has an inbuilt thermistor, (which is a transducer which varies its resistance with respect to its temperature) with which the charging circuit constantly measures the battery temperature. It can even prevent charging the battery if the temperature reaches dangerous level and by controlling its temperature, the life of battery is increased. Mobile battery has more than two terminals, one of which is for this thermistor. See the image in my stackexchange-url ("question") asked in this site.

I have been looking to see if my device (the Samsung GT-S6102B) supports the new Ice Cream Sandwich Android version, but have found nothing. I thought perhaps more knowledgeable people would be able to answer me, so here I ask: Does my device support the OS?
|
Technically, ICS can be put in Samsung Galaxy Y Duos S6102B. Unfortunately, a ready-made ROM featuring ICS for the device isn't available yet. So, unless you are a ROM cooker & developer, you can't do this.

i use the stock rom JB 4.1 on Nexus 7 8G. There is a small play store icon in the top-right corner in app drawer(not app icons in ap drawer). i found that the icon in my cm10 version phone and my friend's nexus 7 can be clicked and open play store directly, but mine wont work. just as it is disabled. why? how to enable it?

From previous experience, rebooting the device should fix the issue.

Currently, my internal storage is running low on space. What can I do besides moving applications to the external memory, as to free up more space, but preserve my current applications and avoid uninstalling? (Some of them won't be moved)

The only way to do this is linking apps to SD card. First : Rooting. stackexchange-url ("How do I root my device?") Disclaimer : I'm NOT responsible to any damage you do to your phone ,Although it is very rare for someone to damage his phone while rooting (or a myth), and Rooting might void your warranty , some warranty policies void if rooted and some other void when unlocking bootloader (i.e installing custom mod) ,I did both actually. Second : Partitioning SD card. Linking apps to SD card requires a second partition on SD card. XDA Developers - Partitioning SD card Third : Activating Link2SD or S2E. You can use one of these apps to link apps to SD card(I prefer Link2SD) : Link2SD S2E If you use link2sd you must choose the type of your ext partition at the first open of the app ,then restart ,if you restart and the app tells you the same message see BONUS section of my answer. Fourth : Linking apps to SD card. This is using Link2SD (I didn't experience with S2E) : After activating Second Partition of your SD card you should now link apps to SD card. NOTE : an app must be on internal memory before it can be linked , if you try to link an app while it's on SD card it will be moved to internal then linked ,so make sure there is enough space to move it. when you long press on an app ,a context menu appears ,press <code> Create Link </code> to link the app. Bonus : Manually mounting second partition : first you must install this app to mount it: Terminal Emulator then open the terminal emulator(and make sure you give it root access),and type the following (each line standalone): <code> su mount -t ext2 /dev/block/mmcblk0p2 /data/sdext2 </code> now open link2SD and <code> Menu > More > Quick Restart </code> it will restart your android system (not your phone),However you must do these steps every time you restart the phone (not via Link2SD)
