private void startForeground() {

Code: Select all

    Intent activityIntent = new Intent(this, MainActivity.class);

< /code>

Und OnStartCommand ist: < /p>

public int onStartCommand(Intent intent, int flags, int startId) {
Log.i(TAG, "Service onStartCommand() is called");

startForeground();

mResultCode = intent.getIntExtra("code", -1);
mResultData = intent.getParcelableExtra("data");
mScreenWidth = intent.getIntExtra("width", 720);
mScreenHeight = intent.getIntExtra("height", 1280);
mScreenDensity = intent.getIntExtra("density", 1);
isVideoSd = intent.getBooleanExtra("quality", true);
isAudio = intent.getBooleanExtra("audio", true);

mMediaProjection = createMediaProjection();
mMediaRecorder = createMediaRecorder();
mVirtualDisplay = createVirtualDisplay();
mMediaRecorder.start();

return Service.START_STICKY;
}
< /code>

Und die Ausnahme ist in dieser Methode auf GetMediAProjection: < /p>

 private MediaProjection createMediaProjection() {
Log.i(TAG, "Create MediaProjection");
return ((MediaProjectionManager) Objects.requireNonNull(getSystemService(Context.MEDIA_PROJECTION_SERVICE))).
getMediaProjection(mResultCode, mResultData);
}
