But Delayedoprationpurgatory set the tickms to 1ms, so this error can be ignored. The Reaper thread delays the poll element from the Delayqueue and handles the delay caused by the poll element. These are basically not controllable. This will cause a timertask to be committed at some point

Android Timer Timertask,timer, to update the main thread UI in TimerTask, since the Android programming model does not allow the main thread UI to be updated in a non-main thread, It is therefore necessary to update the main thread UI in Java's timertask with the handler implementation of Android.Now gives a simple example.
