strong text private void startForeground() {

    Intent activityIntent = new Intent(this, MainActivity.class);
    activityIntent.setAction("stop");
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            }
        }
    } else {
        startForeground(0, new Notification());
    }

}

and onStartCommand is :

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;
}

and exception is in this method on getMediaProjection:

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

Answer 1

Add android:foregroundServiceType="mediaProjection" to the <service> element in the manifest for your service.
