If I have a Handler handler = new Handler() and run a delayed task for it handler.postDelayed(xxx, xxx), is that possible to check has the postDelayed() was called or not?

Runnable runnable = ( ) -> { System. out. println( "Running the runnable at " + Instant. now() ); }; ScheduledExecutorService scheduledExecutorService = Executors.
postDelayed(Runnable r, Object token, long delayMillis) Causes the Runnable r to be added to the message queue, to be run after the specified amount of time elapses. final void. removeCallbacks(Runnable r)
A Handler allows communicating back with UI thread from other background thread . This is useful in android as android doesn't allow other threads to communicate directly with UI thread. A Handler allows you to send and process Message and Runnable objects associated with a thread's MessageQueue.
is that possible to check has the postDelayed() was called or not?
One quick fix, in method assign some boolean variable to true and then just perform checking.
