[bug] Screen Share on Android target API 34+ crashes with security warning #524

Closed kNoAPP closed 4 days ago

Describe the bug After Android API level 34 (impacting Android 14), screen-share functionality according to the LiveKit documentation results in an app crash event.

E/AndroidRuntime(16537): java.lang.RuntimeException: Unable to start service de.julianassmann.flutter_background.IsolateHolderService@ceb8b4b with Intent { act=START cmp=com.remotelegal.astra/de.julianassmann.flutter_background.IsolateHolderService }: java.lang.SecurityException: Starting FGS with type mediaProjection callerApp=ProcessRecord{5ba1ad5 16537:com.remotelegal.astra/u0a549} targetSDK=34 requires permissions: all of the permissions allOf=true [android.permission.FOREGROUND_SERVICE_MEDIA_PROJECTION] any of the permissions allOf=false [android.permission.CAPTURE_VIDEO_OUTPUT, android:project_media]

To Reproduce Set the example app's build.gradle target SDK to 34 or higher (currently 31). This is reproducible despite the changes in https://github.com/livekit/client-sdk-flutter/pull/470.

Expected behavior Android API level 34+ should have instructions documented to fix this issue. Otherwise, a general warning about targeting API 34+ should be added to the documentation.

Please note, you can work around this issue by using a target of Android API 33.

To do screenshare on Android, you need flutter_background package, then you also need to make sure in the AndroidManifest.xml that:

I've tried change the targetSdkVersion to 34 and it still works correctly! Hope this helps!

Issue still present, but under a different error. Opening a new issue with video.
