How To Destroy CoundownTimer in Java when the button is pressed?

I make a timer with a count time of 5 seconds, then when I press the exit button the counter automatically stops?

Here is my timer code:

    public void startTimer(final long finish, long tick) {
        CountDownTimer t;
        t = new CountDownTimer(finish, tick) {

            public void onTick(long millisUntilFinished) {
                long remainedSecs = millisUntilFinished / 1000;
                textTimer.setText("" + (remainedSecs / 60) + ":" + (remainedSecs % 60));// manage it accordign to you
            }

            public void onFinish() {
                textTimer.setText("00:00");
                Toast.makeText(FloatingVideoWidgetShowService.this, "Waktu Habis", Toast.LENGTH_SHORT).show();
                long seek = videoView.getCurrentPosition();
                videoView.setKeepScreenOn(false);
                stopSelf();
                WritableMap args = new Arguments().createMap();
                args.putInt("index", index);
                args.putInt("seek", (int) seek);
                args.putString("url", playingVideo.getString("url"));
                args.putString("type", "close");

                sendEvent(reactContext, "onClose", args);
                onDestroy();
                cancel();
            }
        }.start();

    }

And this is my code when pressing the stop / exit button :

        floatingWindow.findViewById(R.id.btn_deny).setOnClickListener(new View.OnClickListener() {


            @Override
            public void onClick(View view) {
                long seek = videoView.getCurrentPosition();
                videoView.setKeepScreenOn(false);
                stopSelf();
                WritableMap args = new Arguments().createMap();
                args.putInt("index", index);
                args.putInt("seek", (int) seek);
                args.putString("url", playingVideo.getString("url"));
                args.putString("type", "close");

                sendEvent(reactContext, "onClose", args);
                onDestroy();
            }
        });

How so when btn_deny is clicked Cuntdowntimer stops and does not force close?

Thanks.

You can't use onDestroy() to close your activity or fragment. Instead, you need to call finish().

To close the CountDownTimer, you need to make it a class scope variable. Prepare the timer at your startTimer then stop the timer by calling t.cancel() like the following code:

public class YourActivity extends Activity {
   // Declare the variable to be accessed later.
   CountDownTimer t;

   ...

   public void startTimer(final long finish, long tick) {
     t = new CountDownTimer(finish, tick) {
         ...
     }.start();

   }


   private void yourOtherMethod() {

    floatingWindow.findViewById(R.id.btn_deny).setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View view) {
          if(t != null) t.cancel();
          ...
       }
    });
   }

}
