Haptics on Android

[TomZ]

Just a generic question, did anyone manage to get haptics (vibrations) working on Android on their Qt / QML application?

I tried for most of today before giving up.

• the Android call View.performHapticFeedback hits the snag that there doesn't seem to be any way to get a "View" instance in a QML application.
  Using the context.getWindow().getDecoreView() gives you a view, but not sure why, calling the haptics on there didn't do anything.
• Calling the following Java likewise had no effect:

 public static void click(Context context) {
     VibratorManager vm = (VibratorManager) context.getSystemService(Context.VIBRATOR_MANAGER_SERVICE);
     Vibrator vibrator = vm.getDefaultVibrator();
     vibrator.vibrate(VibrationEffect.createPredefined(VibrationEffect.EFFECT_CLICK));
   }

// additionally added to the manifest this line:
 <uses-permission android:name="android.permission.VIBRATE"/>

If anyone knows of a Qt app that successfully added haptics (simple is fine), please do share the details!
