"ReactNative Android app crash. Error while updating property padding in shadow node of type: RCTView",
"This is the error I get\n\nFew things are bugging me here.\nThis crash is happening at random times, in development, and when the app is built for production.\nI found out that problem might be because values for properties like padding and margin are set as strings rather than integers. This is not a problem in my case, because all of them are set as integers.\nI was thinking that it might be an SVG problem, but they don't have any inline style set that would cause this. Or maybe it could be something else with SVG images.\nContent is loaded from WordPress using react-native-render-html but I don't think that this could be the problem.\nI am using "react-native": "0.63.3",\nIf anyone could help me out it would be great :)"

"Canonical reference on JVM internals for programmer/developers",
"The title captures my question fairly well. I'm wondering if there is a good resource or leaping-off point for questions about how a JVM (not just HotSpot, but that's obviously the place to start) implements or handles a specific functionality? I'm not looking for the stuff that's in the JLS or JVM Spec -- I know to go there first. \n\nFor example: When trying to understand performance issues, we often get into conversations not about what the spec says, but what contemporary best-practices look like in practical implementations. For example, there is some urban mythology that says \"final classes perform better in Java because the JVM can inline or otherwise optimize such things.\" Is there a general resource we can turn to in order to evaluate these claims that float around?\n\nI offer an answer to my own question, with HotSpot-specific references. What about other vendors' offerings? Specifics to small JVMs? Multi-core specifics? Platforms specifics, if they make a difference? Specifics to other JVM languages?\n\nJust to head off a couple of potential complaints: 1) This isn't about looking for premature optimizations (and in fact, better understanding of the platform should dissuade a better educated developer!); and 2) I know Java programmers are supposed to focus on nice, portable, run-anywhere code, but for many of us the platform specifics end up mattering!\n\nThis was inspired by some helpful comments on a specific question by Thorbjørn Ravn Andersen. I'm happy to collect some other more helpful examples beyond the one I cite above, to motivate why folks might want these kinds of resources.\n\nSome interesting related questions on SO: Tail-call optimization in JVM, Killer JVM features, optimizations that are going to be useless tomorrow, Differences between JVM implementations.\n\nEdited to Add: I'll award the answer either to the best individual reference mentioned, or to someone who provides a pointer to a website (perhaps built in response to this question) that best concentrates/catalogs JVM implementation wisdom and the practical consequences on client languages and developers."

"How to disable background execution of Adobe AIR app on Android?",

I don't want timers, audio, timelines etc to continue. Pausing/resuming them all myself on Event.DEACTIVATE/Event.ACTIVATE is not really feasible, due to the complexity and structure of the apps.\n\nI have tried explicitly setting 'NativeApplication.nativeApplication.executeInBackground = false', with no effect.\nThere is nothing in my manifest xml that does anything with background execution.\n\nI am using Adobe AIR 16.0.\nI have tested on Samsung Galaxy Note 10.1 2014, Samsung Galaxy S4, which both run Android 4.4+\n\nOn stackoverflow I see a number of questions asking the opposite, so this behaviour seems odd.\n\nThanks!"

"Optimal sequence to brute force solve a keypad code lock",

"Parsing with XStream - empty tags and collections",

"Is it possible to add custom attributes to drools rules?",
"We are going to be implementing a rules engine using Drools for a customer, and one of the requirements is to be able to say that a rule is associated with a particular legal requirement.\n\nFor instance, the law says that a driving licence can only be issued to someone 18 or over, so we have:\n\nrule \"Driving Licence: Age >= 18\"\n when\n $applicant: Applicant(age < 18)\n $application: Application()\n then \n $application.setValid(false);\nend\n\n\nor for the calculation of a tax total\n\nrule \"Tax: Top bracket\"\n when\n $return: Return(income > 44000)\n then \n $application.setTopBracket(true);\nend\n\n\nor similar.\n\nOne solution would be to have the legal requirement in the name:\n\nrule \"Driving Licence: Age >= 18: Section 103 RTA 1988\"\n\n\nThe question: what would be the best way of achieving this? Is the name the only way? Is there a way to add a custom attribute to a rule? If so, can it be mandatory? I could also use comments, but I would prefer to avoid that.\n\nIt would be nice if in the rule trace we could see the trace of these attributes as well, but that isn't vital.\n\nPlease note that I don't want to change the rule logic, I just want to be able to say 'This rule comes from this law'.

I tried encryptionPreference both none and required, but the result is the same.\n\nMy setup code if required:\n\nsession = MCSession(peer: peerID, securityIdentity: nil, encryptionPreference: .none)\nadvertiser = MCNearbyServiceAdvertiser (peer: peerID, discoveryInfo: nil, serviceType: SERVICE_NAME)\nbrowser = MCNearbyServiceBrowser(peer: peerID, serviceType: SERVICE_NAME)\n\n\nIs this an expected behavior or am i doing something wrong? Thanks in advance."

"Data Deletion With iCloud Core Data Sync",
"I have a deployed iCloud-enabled iOS 8 app which syncs a Core Data model. The app deals with evaluating investment properties and records information about the property such as repairs. \n\nI recently received a complaint from a user who entered in 29 repairs for a property only to have them disappear 48 hours later. \n\nThere is no mechanism for deleting model objects in my app that doesn’t involve explicit permission from the user. I don’t believe that the user accidentally deleted 29 objects which is why I am suspicious that a faulty iCloud sync may have had something to do with this. \n\nThe user described that they enter the information on their i-Cloud enabled iPad, but also use their iCloud-enabled iPhone to view the synced data. If the sync used the iPhone data to overwrite the iPad data, the objects could be deleted. \n\nIs anyone aware of such an issue with iCloud? Does anyone have other general ideas on what the issue may be?"

"Is there a way to disable popup blocker in Safari using Javascript?",

So I used \"window.location\", and it worked out perfectly in chrome, firefox and IE.\n\nBut safari is throwing an error \"resource interpreted as document but transferred with mime type 'application/vnd.ms-excel'\". For this I have changed the code little bit from \"window.location\" to \"window.open('url','_blank')\". It solved the mime type error. But when popup blocker is enabled in safari, it is not even prompting the user to give permission to open popup. But all other browsers did that.\n\nSo my question is! Is there any possibility that, I can turn off the popup blocker in safari either using javascript or jQuery (I Know we cannot override the browser settings using the js or jQuery)? Or at-least can we know weather pop-up blocker is enabled or not?"

So I simply wasted some more of my time :)\n\nWhat kind of service/API has to be used for personal OneDrive access (via a hotmail account) ? What kind of token am I getting and what can I use it for?

"Integrating Android project with CircleCi, only test against one build variant with connectedAndroidTest command?",
"I'm battling against CircleCi at the moment, so many issues as I am new to it. Right now my app takes 20 minutes to build, because it's builds every productFlavour we have. In my circle.yml file I have the following command:\n\n- ./gradlew --stacktrace connectedAndroidTest:\n timeout: 1200\n\n\nThe full circle.yml file starts the emulator and does a clean build of one of our productFlavours, called test. I can easily ensure only this productFlavour is built by running the following command:\n\n - ./gradlew clean assembleTestDebug -PdisablePreDex\n\n\nThis takes about 1 minute to build. My issue is now with the connectedAndroidTest command which then goes on to build all of our build variants with all build types (release and debug), then runs our test against them, this is very time consuming. Hence why our build times take 20 minutes.\n\nIs there a way I can tell the connectedAndroidTest command in my circle.yml file to only run against TestDebug?\n\nI tried adding the build variant to the end (connectedAndroidTestTestDebug) but this caused the following exception on CircleCi:\n\n'connectedAndroidTestTestDebug' not found in root project 'my_project'.\n\n\nWould appreciate any advice on the matter, from my experience, CircleCi has been a big pain to set up, I'm in contact with their support staff but they are in different timezones which is not ideal so progress in slow. I'm hoping someone who has set up an Android project on CircleCi with unit tests has figured out a way to only run them against one productFlavour/Build variant.\n\nThanks in advance for any advice!"

"In Android, how can I programmatically set an AutoCompleteTextView at the start of an activity? (Java)",
"I'm using the AutoCompleteTextView as an ExposedDropdownMenu per the Google Material Guidelines. First I would like to state that I am able to successfully set the AutoCompleteTextView's text value programmatically by waiting ~300ms after the onCreate() function is called, with the proper values inside of the dropdown suggestion menu. However, when I set the AutoCompleteTextView's text programmatically beforehand (e.g. inside of the onCreate() w/o delay), a weird issue arises where the dropdown menu of the AutoCompleteTextView is empty for some reason (and no it's not because of filtering).\n\nNOTE: I have modified this code from my original source code to make it easier to understand and less complex.
