vibrate
(long[] pattern, int repeat)
Vibrate with a given pattern.
Pass in an array of ints that are the durations for which to turn on or off
the vibrator in milliseconds. 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.
To cause the pattern to repeat, pass the index into the pattern array at which
to start the repeat, or -1 to disable repeating.
This method requires the caller to hold the permission
VIBRATE.
