Welcome back coders In this article we will touch very basic and interesting topic on how to call an function after specific time. If you are looking for how to call an function in certain time interval when app is running in background then have you are on the accurate location .

Let’s get started 

Using Handler class and Runnable Interface

Handler handler = new Handler();
Runnable runnable ;
int delay = 5000;

protected void onPause(){
    handler.postDelayed(runnable = new Runnable() {
        @Override
        public void run() {
            handler.postDelayed(runnable, delay);
            methodToRun();

    },delay);
    super.onPause();
