This code vibrates the phone for 1000 milliseconds. After getting the vibrator service with Context.getSystemService we call Vibrator.vibrate for a given time in milliseconds.

// 1. Vibrate for 1000 milliseconds
long milliseconds = 1000;
v.vibrate(milliseconds);

// 2. Vibrate in a Pattern with 500ms on, 500ms off for 5 times
long[] pattern = { 500, 300 };
v.vibrate(pattern, 5);

For this to work, you will have to add the android.permission.VIBRATE permission to your Manifest.xml

In Android 2.2 the line v.vibrate(pattern, 5); causes some kind of 'index out of bounds' exception as the 5 is an index into pattern. The 5 is not the number of times to repeat.
Try: v.vibrate(pattern, -1); // no repeat

long[] pattern = { 0, 200, 500, 200, 500, 200, 500 }; v.vibrate(pattern, 1); // repeat until v.cancel();
