Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

currentAnimationTimeMillis

Added in API level 1
public static long currentAnimationTimeMillis ()

Returns the current animation time in milliseconds. This time should be used when invoking Animation.setStartTime(long). Refer to SystemClock for more information about the different available clocks. The clock used by this method is not the "wall" clock (it is not System.currentTimeMillis).

Returns
long the current animation time in milliseconds
