How can I request the vibrate permission?

Here is the link to the reference

Add this to your manifest, as a direct child of the manifest element:

<uses-permission android:name="android.permission.VIBRATE" />

This is how you let the phone Vibrate thru code:

// Get instance of Vibrator from current Context
Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);

// Vibrate for 300 milliseconds
v.vibrate(300);

For a more creative pattern try the star wars theme =D

v.vibrate(new long[]{0, 500, 110, 500, 110, 450, 110, 200, 110, 170, 40, 450, 110, 200, 110, 170, 40, 500}, -1);
