[kNoAPP]

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.

Crash at 3:29 in video.

To Reproduce Set the example app's build.gradle target SDK version to 34 or higher (currently 31).

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.

Media projection

Foreground service type to declare in manifest under android:foregroundServiceType mediaProjection

Permission to declare in your manifest FOREGROUND_SERVICE_MEDIA_PROJECTION

Constant to pass to startForeground() FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION

Runtime prerequisites Call the createScreenCaptureIntent() method before starting the foreground service. Doing so shows a permission notification to the user; the user must grant the permission before you can create the service.

After you have created the foreground service, you can call MediaProjectionManager.getMediaProjection().

Description Project content to non-primary display or external device using the MediaProjection APIs. This content doesn't have to be exclusively media content.

Alternatives To stream media to another device, use the Google Cast SDK.
