Title: Update AndroidManifest to include permission to vibrate the device

Here's the actual code to make it vibrate.

Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
// Vibrate for 500 milliseconds
v.vibrate(500);

I'm not exactly sure where you want this code, so I'm just giving it to you now.
