Remarks

Configuration for capturing audio played by other apps.

When capturing audio signals played by other apps (and yours), you will only capture a mix of the audio signals played by players (such as AudioTrack or MediaPlayer) which present the following characteristics: <ul> <li> the usage value MUST be AudioAttributes#USAGE_UNKNOWN or AudioAttributes#USAGE_GAME or AudioAttributes#USAGE_MEDIA. All other usages CAN NOT be captured. </li> <li> AND the capture policy set by their app (with AudioManager#setAllowedCapturePolicy) or on each player (with AudioAttributes.Builder#setAllowedCapturePolicy) is AudioAttributes#ALLOW_CAPTURE_BY_ALL, whichever is the most strict. </li> <li> AND their app attribute allowAudioPlaybackCapture in their manifest MUST either be: <ul> <li> set to "true" </li> <li> not set, and their targetSdkVersion MUST be equal to or greater than android.os.Build.VERSION_CODES#Q. Ie. Apps that do not target at least Android Q must explicitly opt-in to be captured by a MediaProjection. </li></ul> <li> AND their apps MUST be in the same user profile as your app (eg work profile cannot capture user profile apps and vice-versa). </li> </ul>

An example for creating a capture configuration for capturing all media playback:

MediaProjection mediaProjection;
                // Retrieve a audio capable projection from the MediaProjectionManager
                AudioPlaybackCaptureConfiguration config =
                    new AudioPlaybackCaptureConfiguration.Builder(mediaProjection)
                    .addMatchingUsage(AudioAttributes.USAGE_MEDIA)
                    .build();
                AudioRecord record = new AudioRecord.Builder()
                    .setAudioPlaybackCaptureConfig(config)
                    .build();
