Use of Android-Vibrator

The vibration in the Android mobile phone is implemented by vibrator. To set a vibration event, you need to know the duration and cycle of the vibration.

In Android, the vibration time is calculated in one millisecond (1/1000 seconds). Therefore, if the set time value is too small, it cannot be felt.

Call vibrate (long [] pattern, int repeat) of vibrator.

The previous parameter is an array of effects for vibration. The second parameter is-1, indicating that only one vibration occurs. If it is 0, the vibration will continue.
