I have implemented the timer functionality in android app, I able to finish the timer from other local methods by calling timerObject.cancel() . Its working perfectly. But when I tried to call same in onTick() method for specific condition, i am not able to cancel the timer, it last till the timer time ends. How can i cancel the timer? AFAIK You can not do that But there is Drop-in alternative for the Android CountDownTimer class, but which you can cancel from within onTick.

I am new to Android Development and trying to make little Game. CountDownTimer.cancel() is not working for me. Any Idea? Thank Your for your Answer! CountDownTimer cdt = new CountDownTimer(120000, 1000) { public void onTick(long millisUntilFinished) { maxTime = (int) (millisUntilFinished / 1000); timer.setText(String.valueOf(maxTime)); } public void onFinish() { } }; if (startTimer == true) { cdt.start(); } else { cdt.cancel(); } I have to do an assumption right here because the code doesn't show much! apparently you are using the countDownTimer inside your onCreate as an inner class so that

Handler.postDelayed(Runnable) vs CountdownTimer

See the sample code below Handler new Handler().postDelayed(new Runnable() { @Override public void run() { //DO SOMETHING } }, 1000); CountDownTimer new CountDownTimer(1000, 1000) { public void onFinish() { //DO SOMETHING } public void onTick(long millisUntilFinished) {} }.start(); 回答1: The Handler should offer you better

How to set Service/StartForeground to work CountDownTimer properly

Next I try run this in MainActivity but without success. I still try to implement my code to work this CountDownTimer properly in a background. On official Android website I see that
