To make the device vibrate is a simple matter of calling the vibrate function.



On Android you have access to more control over the length and pattern of the vibration.

You can control the length of the vibration by passing the first parameter to the vibrate function. This parameter specifies the length of the vibration in milliseconds.

For example, vibrate for 1 second:

Vibration.service.vibrate( 1000 );

You can set vibration patterns to control the length and gap between vibrations. For example, the following sets a vibrate pattern on for 200 milliseconds then off for 500 twice:

Vibration.service.vibrate( 0, [0, 200, 500, 200, 500] );

The last parameter allows you to repeat the pattern. The value is the index into the pattern array at which to repeat. The default -1 will not repeat the pattern, and 0 will repeat the complete pattern.

The following example will vibrate with the pattern, repeating the entire pattern:

Vibration.service.vibrate( 0, [0, 200, 500, 200, 500], 0 );

If you are repeating the pattern you must call cancel() to stop the vibration.


You can cancel an active vibration by calling cancel:



On iOS all the parameters to vibrate are ignored and the function will produce exactly 0.4 seconds of vibration and 0.1 seconds of silence.
