return faceServiceClient.detect() this line code not working in android 11

private class DetectionTask extends AsyncTask<InputStream, String, Face[]> {
    @Override
    protected Face[] doInBackground(InputStream... params) {

        try {
            publishProgress("Detecting...");

            // Start detection.

• return faceServiceClient.detect(
• params[0], /* Input stream of image to detect */
• true, /* Whether to return face ID */
• false, /* Whether to return face landmarks */
• /* Which face attributes to analyze, currently we support:
• age,gender,headPose,smile,facialHair */
