Vibration Patterns

suggest change

You can create vibration patterns by passing in an array of longs, each of which represents a duration in milliseconds. The first number is start time delay. Each array entry then alternates between vibrate, sleep, vibrate, sleep, etc.

The following example demonstrates this pattern:

long[] pattern = {0, 100, 1000, 200, 2000};

To cause the pattern to repeat, pass in the index into the pattern array at which to start the repeat, or -1 to disable repeating.

Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(pattern, -1); // does not repeat
vibrator.vibrate(pattern,  0); // repeats forever
