问题 Strange issue here. I've just downloaded Android Q preview in my Android Studio to try it within an emulator. However, no matter what device type I select, when I start the emulator with the selected Q image I get black screen on the emulator without any kind of feedback. I've already tried to delete and recreate the emulator, as well as wiping its data. Below a picture of my emulator state at the moment.

问题 I have stored image file into External Directory through Media store but it doesn't required permission for AndroidQ, even i have not mention permission in manifest. compileSdkVersion 29 defaultConfig { minSdkVersion 21 targetSdkVersion 29 } Note: Any application can store files on external storage without requesting permission to user, so is it break down security violation? 回答1: The argument, as I understand it, is that with MediaStore you are only supposed to be able to write to a few

问题 This question already has answers here : Android 8: Cleartext HTTP traffic not permitted (20 answers) Closed 22 days ago . I was trying fix an issue here on Stackoverflow as the person was trying to make use of WebView to load Facebook's website "https://facebook.com/" but couldn't get it done. I looked at the code and saw that the onReceivedSslError() method was not overridden. I overrode it and tested it out myself on Android emulators running Android 9 (API level 28) and lower and it

问题 Background Using root, I know that for a single APK file, we can use the "libsu" library (here) to install as such: val installResult = Shell.su("pm install -t \"$filePath\"").exec() And if that failed (fails on new Android versions, not sure from which), as such (written about this here): val installResult = Shell.su("cat \"$filePath\" | pm install -t -S ${apkSource.fileSize}").exec() I also know that things got quite messy when it comes to installing split APK files (as shown here).

问题 As Android is serious about security and trying to make new android versions more secure, its becoming tough for developers to keep up-to date with new security features and find old methods alternatives to make their app compatible with old features. This question is about IMEI in New Android 10!

问题 In my VPN application up until Android-9, it was possible to read the /proc/net/tcp files from apps targeting API level < 28. Access from apps no longer seems to work in Android Q. I'm getting an error /proc/net/tcp: open failed: EACCES (Permission denied) while trying to read the file.

问题 Background On recent Android versions, ever since Android 8.1, the OS got more and more support for themes. More specifically dark theme. The problem Even though there is a lot of talk about dark mode in the point-of-view for users, there is almost nothing that's written for developers. What I've found Starting from Android 8.1, Google provided some sort of dark theme . If the user chooses to have a dark wallpaper, some UI components of the OS would turn black (article here).
