<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 

   xmlns:app="http://schemas.android.com/apk/res-auto"

 android:orientation="vertical"  

 android:layout_height="match_parent"

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void notify(View view) {
      NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        NotificationCompat.Builder notify = new NotificationCompat.Builder(this);
        notify.setSmallIcon(R.drawable.ic_camera_alt_black_24dp);
        notify.setContentText("Hi there");
        notify.setContentTitle("Hello");
        Intent intent = new Intent(MainActivity.this,MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,0);
