abstract void	cancel() Turn the vibrator off.
abstract boolean	hasVibrator() Check whether the hardware has a vibrator.
void	vibrate(long[] pattern, int repeat) Vibrate with a given pattern.
void	vibrate(long milliseconds) Vibrate constantly for the specified period of time.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public abstract void cancel ()

Added in API level 1

Turn the vibrator off.

This method requires the caller to hold the permission VIBRATE.

public abstract boolean hasVibrator ()

Added in API level 11

Check whether the hardware has a vibrator.

Returns

True if the hardware has a vibrator, else false.

public void vibrate (long[] pattern, int repeat)

Added in API level 1

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.

Parameters

pattern	an array of longs of times for which to turn the vibrator on or off.
repeat	the index into pattern at which to repeat, or -1 if you don't want to repeat.

public void vibrate (long milliseconds)

Added in API level 1

Vibrate constantly for the specified period of time.

This method requires the caller to hold the permission VIBRATE.

Parameters

milliseconds	The number of milliseconds to vibrate.
