- handler
- The IdleHandler to be added.
Add a new NoType:android/os/MessageQueue$IdleHandler;Href=../../../reference/android/os/MessageQueue.IdleHandler.html to this message queue. This may be removed automatically for you by returning false from NoType:android/os/MessageQueue$IdleHandler;Href=../../../reference/android/os/MessageQueue.IdleHandler.html#queueIdle() when it is invoked, or explicitly removing it with MessageQueue.RemoveIdleHandler(.IIdleHandler).
This method is safe to call from any thread.
