"Activity destroyed after 1 hour",
"I'm new to Android development. I'v developed an android application which needs to store the connection/data even after 1 hour. Currently I have all the data and the connections(chromecast mediaplayer) in a singleton class. But, when the user puts the app into the background for about an hour, the activity is destroyed so the connections,data etc are lost causing my app to crash when re-launched. \n\nI've read up on the android services, Can I use these services to hold the singletons so even when the activities are destroyed I can have data binded back to the views when re-launched? \n\nOr is there a way to make sure that the activities are not destroyed when android decides to do a cleanup? \nPlease advise\n\nThanks."

"Pybind11: returning a large array in a C++ function significantly increases computing time in python",
"I wrote a little C++ Script and used pybind11 to make the C++ function available in python. When called from python, the C++ function takes about 4 seconds to terminate. The C++ functions returns a large array of length 54.346.383.\nOut of curiosity, I modified the C++ function and returned a different array of length 7373 without changing anything else in the code. Now the C++ function terminates in 1 second. So as I understand this the transfer of an object from C++ to Python becomes a huge bottleneck as size of the object increases.\nIs there a smarter approach to handle this issue? Maybe working with pointers?

"How to toggle a slide menu from the left with jQuery?",
"For a mobile page to be used on iPhones etc. I am trying to create a menu which will slide in from the left and push the current content out to the right much like in phone apps. With a touch anywhere in the displayed menu (other than a link) the menu should disappear again and the page should be displayed again as before.\n\nI use the http://aozora.github.io/bootplus/index.html Bootplus CSS to have a decent look of the site and make it also responsive.\n\nI was able to get the slide in effect going nicely using the following jQuery code:\n\n$('#leftmenu').hide();\n$('#button').on('click',function(){\n $('#content').css({'position':'fixed'}).animate({\"left\":\"85%\"});\n $('#leftmenu').css({'position':'fixed', 'width':'85%'});\n $('#leftmenu').fadeIn('slow');\n});\n\n\nFor the menu, I have the following html.\n\n<div id=\"leftmenu\" class=\"container\" style=\"width: 85%; left:0%; height: 100%; background-color:silver\">\n <br />\n <p><h3>Quick links</h3></p>\n <p><h4><a href=\"\">Home</a></h4></p>\n <p><h4><a href=\"\">Page 1</a></h4></p>\n <p><h4><a href=\"\">Page 2</a></h4></p>\n</div>\n<div class=\"navbar .navbar-inverse\" style=\"background-color:silver; vertical-align:middle\">\n <a class=\"btn btn-primary dropdown-toggle\" data-toggle=\"dropdown\" href=\"#\">\n <i id=\"button\" class=\"fa fa-bars\"></i>\n </a>\n</div>\n\n\nBut when I hide the menu with the code below, the page no longer shows centered in the middle, but aligned to the left with no left margin anymore. \n\n$('#leftmenu').on('click',function(){\n $('#content').css({'position':'absolute'}).animate({\"left\":\"0%\"});\n $('#leftmenu').fadeOut('slow');\n $('#content').fadeIn('slow');\n});\n\n\nI understand that I do that with the css code, but I struggle to make it work with a toggle mechanism with which I can get back to the previous css settings without having to redefine all from scratch.\n\nAnother issue I face is that whenever I touch the menu on the left, I need to touch twice to make it disappear. To show the menu, it works with a single touch on the Menu button, yet the hiding requires two touches.\n\nThanks a million for your help."

"APK not compatible with newest Android build",
"I am working onan app that is currently published on the Play Store. When using an Android device with version 5.1.1 on it, the play store says \"Your device isn't compatible with this versions\" and I'm trying to determine the specific reason why and how to work around it.\n\nThe existing app's Android.Manifest file has the following in it:\n\n <uses-sdk minSdkVersion=\"13\" targetSdkVersion=\"21\"/>\n\n\nI thought that maybe it was the \"targetSDKVersion\" causing the problem. I don't have the APK that was originally published, but I figured I could test my hypothesis by generating a new app with the same uses-sdk manifest items.\n\nI created a new app with the latest Android Studio and the same uses-sdk values and published it, and strangely it is available on my 5.1.1 device.\n\nI decided to investigate further and I pulled both APKs down to my desktop and then used apktool to extract the contents of each to see if anything stood out.\n\nWhat I did find is that the non-working APK has this in the extracted manifest:\n\n<manifest xmlns:android=\"http://schemas.android.com/apk/res/android\" package=\"com.redphx.deviceid\" platformBuildVersionCode=\"21\" platformBuildVersionName=\"5.0.1-1624448\">\n\n\nAnd the working APK has the following\n\n<manifest xmlns:android=\"http://schemas.android.com/apk/res/android\" package=\"com.opennetcf.ctacke.androidsample\" platformBuildVersionCode=\"23\" platformBuildVersionName=\"6.0-2166767\">\n\n\nRight now my assumption is that the platformBuildVersionCode must be the culprit.\n\nSo my questions are:\n\n\nIs my assumption correct, that this is why one APK is not working for 5.1.1?\nI assume the APK compiler sets the platformBuildVersionCode attribute. I specifically set the targetSdkVersion to 21 in the working application, and I see that value in the extracted yml, but the platformBuildVersionCode still says 23. Where does that information come from, if not the uses-sdk information?\nIs there a fix, short of rebuilding a new APK and re-publishing?\n\n\nI assume that re-publishing is the likely route, but I'm hoping to head off having this problem recur in the future, so I'd really like to understand the answers to #1 and #2.\n\nupdate\n\nThe merged manifest for the working APK is the same as what is in the application itself, so no reference to 23 at all.\n\n<uses-sdk \n minSdkVersion=\"13\" \n targetSdkVersion=\"21\"/>\n\n\nOn the working system, build.gradle contains the following:\n\nandroid {\n compileSdkVersion 23\n buildToolsVersion \"23.0.1\"\n\n defaultConfig {\n applicationId \"com.opennetcf.ctacke.androidsample\"\n minSdkVersion 13\n targetSdkVersion 21\n versionCode 1\n versionName \"1.0\"\n }\n buildTypes {\n release {\n minifyEnable false\n proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro\n }\n }\n}\n\ndependencies {\n compile filetree(dir: 'libs', include: ['*.jar'])\n compile 'com.android.support:appcompat-v7:23.0.1'\n}\n\n\nSo I assume that this is where that info comes from, but how it gets to the APK still isn't all that clear.\n\nI don't have either for the non-working APK since it was built by the app release team before I came on the project and I have no idea if they keep any of these intermediate outputs. I'm investigating that.\n\nedit 2\n\nThe extracted yml from both APKs (which shows the uses-sdk info) is below. It looks like the non-working minimum version is significatly lower (5) than the working (13).\n\nworking:\n\nversion: 2.0.1\napkFileName: oncf.apk\nisFrameworkApk: false\nusesFramework:\n ids:\n - 1\nsdkInfo:\n minSdkVersion: '13'\n targetSdkVersion: '21'\npackageInfo:\n forced-package-id: '127'\nversionInfo:\n versionCode: '1'\n versionName: '1.0'\ncompressionType: false\nsharedLibrary: false\n\n\nnon-working:\n\nversion: 2.0.1\napkFileName: ytb.apk\nisFrameworkApk: false\nusesFramework:\n ids:\n - 1\nsdkInfo:\n minSdkVersion: '5'\n targetSdkVersion: '21'\npackageInfo:\n forced-package-id: '127'\nversionInfo:\n versionCode: '4'\n versionName: 1.1.2\ncompressionType: false\nsharedLibrary: false"

"How to let client detect updated data from server?",
"I am currently making a simple client-server chatroom, but I am struggling with what the server should do when a new message appears.\n\nMy current solution is to just send the updated data to the client when they update theirs. In practice, this would mean that a client would only get new messages when they send a message themselves. Not very useful...\n\nI also thought of another way, which is to have the client request the server for information every 3 or so seconds, but that would clog up the server with a large number of people.\n\nMy third idea would be to have the server connect to the clients when a new message appears, but that would need the server to remember their IP address and have the client use a server too. (Sounds like P2P.)\n\nMost of my code is copied from this part of the docs so you can check against it too.\n\n\n\nHere is my current client side code.\n(Note: To send a 'message', you need to type asyncio.run(echo_client('username', 'message')).

"Currently I use the following Cypher / APOC query to search the relationship type TO by a certain property (user id):\n\nCALL apoc.index.relationships('TO','user:16c01100-aa92-11e3-a3f6-35e25c9775ff') YIELD rel, start, end\nWITH DISTINCT rel, start, end\nMATCH (ctx:Context)\nWHERE rel.context = ctx.uid \nETURN DISTINCT start.uid AS source_id,\nstart.name AS source_name,\nend.uid AS target_id,\nend.name AS target_name,\nrel.uid AS edge_id,\nctx.name AS context_name,\nrel.statement AS statement_id,\nrel.weight AS weight;\n\n\nI want to make it posible to not only search the index TO but also the index AT (AT type of relationships), so that the resulting rel parameter contains both TO and AT relationships. \n\nI would imagine it would be something as simple as adding an OR operator, like this:\n\nCALL apoc.index.relationships('TO','user:16c01100-aa92-11e3-a3f6-35e25c9775ff') OR\napoc.index.relationships('AT','user:16c01100-aa92-11e3-a3f6-35e25c9775ff') YIELD rel, start, end\nWITH DISTINCT rel, start, end\nMATCH (ctx:Context)\nWHERE rel.context = ctx.uid\nRETURN DISTINCT start.uid AS source_id,\nstart.name AS source_name,\nend.uid AS target_id,\nend.name AS target_name,\nrel.uid AS edge_id,\nctx.name AS context_name,\nrel.statement AS statement_id,\nrel.weight AS weight;\n\n\nBut it doesn't work...\n\nMaybe there's somethign I could do that I get the rels from these two apocs and then simply conflate them together into one rel but I don't really get how to do that... Or maybe there's an easier way I don't see?"

I would like:\n\n(1) The lines in the legend to be a lot thicker\n\n(2) The lines on the graph to be slightly thicker\n\n(3) This one might be tricky.

How can I \nfacet upon a field present in the auxillary document? \n\nFirst, here's a gist dump of my test core index (4 docs + 4 aux docs) \nhttps://gist.github.com/anonymous/2774b54e667778c71492\n\nNext, here's a simple facet query only on the aux . While this works, it \nonly returns auxillary documents \nhttps://gist.github.com/anonymous/a58b87576b895e467c68\n\nFinally, I tweak the query using a SOLR join ( \nhttps://wiki.apache.org/solr/Join ) to return the main documents (which it \ndoes), but the faceting returns no results. This is what I'm hoping someone \non this list can answer . \nHere is the gist of that query \nhttps://gist.github.com/anonymous/f3a287ab726f35b142cf\n\nAny answers, suggestions ? \n\nThanks"

"Use glyphicons in razor views in ASP.NET Core 5",
"I'm migrating an ASP.NET MVC 5 web app to ASP.NET Core (with .NET 5). In the previous web app I used glyphicons, but in the new one it seems that there are no available.\nI created a new ASP.NET Core Web App (Model-View-Controller) project with .NET 5. I didn't change anything about bootstrap, it is v4.3.1, and if I use this HTML code <span class="glyphicon glyphicon-pencil"> </span> no icon is shown.\nI tried this solution, adding a link to v3.4.0 stylesheet, but this changes the style of the current web page.\nIs it possible to use glyphicons in ASP.NET Core project without changing web's main style?"

"adding users to answers_watchers table from comment.rb",
"I have the following code in my Answer.rb model of my Rails app. After a user has posted an answer (to a question), they get added to a list to be notified if a comment is posted on the answer.\n\nAnswer.rb\n\n has_and_belongs_to_many :watchers, :join_table => \"answer_watchers\", :class_name => \"User\"\n\nafter_create :creator_watches_me\n private \n\n def creator_watches_me\n self.watchers << user\n end \n\n\nThis (together with code not shown) works to notify the user who answered the question if a comment is posted. However, if that same user posts a comment in reply, I want the original commenter to be notified if a comment is added by the answerer or anyone else. Therefore, I want to add anyone who makes a comment on an answer to this same list--but separate lists should be kept for each instance of an answer obviously. Here's where I'm running into trouble. \n\nI'm assuming it (the new commenter) has to be added to the answer instance rather than the class, although I'm not entirely sure how to do that. The code below is all broken. I'm just trying to play around with how it might work without success.\n\nIn my comment.rb model, I added this code that would pass the user to a method add_to_watchers in the Answer model\n\ncomment.rb\n\n after_create :creator_watches_me\n private \n\n def creator_watches_me\n Answer.add_to_watchers(user)\n end \n\n\nand in the Answer.rb model, I had this\n\n def add_to_watchers(user)\n self.watchers << user\n end \n\n\nbut now I can't add a comment at all. I get this error\n\nundefined method `add_to_watchers' for #<Class:0x007faead33f7f8>\n\n\nOne problem I'm guessing I might be having is I don't know how to refer to the instance of the Answer from the comment model and how to pass that instance to Answer.rb so it knows which answer the user should be added to. That could be totally wrong of course :( I've read a few blog posts on instance and class methods but I'm having trouble getting it sorted out in my code, if that's even the issue I'm having. \n\nSo you know, there is an association between Answer and Comment. Answer.rb has_many :comments."
