The Android Vibrator feature is supported by the majority of the android devices. It is easy to understand. First of all the feature requires premissions. So first thing you need to do is edit your AndroidManifest.xml:
Next: The Vibrator service.
Vibrator vibrator = (Vibrator) this.context.getSystemService(Context.VIBRATOR_SERVICE);
"The first value indicates the number of milliseconds to wait before turning the vibrator on. The next value indicates the number of milliseconds for which to keep the vibrator on before turning it off. Subsequent values alternate between durations in milliseconds to turn the vibrator off or to turn the vibrator on."
