add this code inside onCreate() method

timer = new Timer();
timer.scheduleAtFixedRate(new RemindTask(), 0, 3000); // delay in seconds

create a new class like this

        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                public void run() {

                    // call your method here

                   getImageFromApi();
                }
            });
