Pause CountDownTimer in Android when activity is not in front

Question

I have an activity that uses a CountDownTimer that counts down from 10. How do I pause that timer when the activity is no longer in focus, like if the user get a call or som

No need to create a new Timer, just set the millisUntilFinished = total. For instance

private CountDownTimer cdTimer;
private long total = 30000;

        ...
        toggleButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view){
                if(toggleButton.isChecked()) {
                    startCountDownTimer();
                }else{
                    cdTimer.cancel();
                }
            }
        });
        ...

    private void startCountDownTimer() {
        cdTimer = new CountDownTimer(total, 1000) {
            public void onTick(long millisUntilFinished) {
                //update total with the remaining time left
                total = millisUntilFinished;
                nTimeLabel.setText("seconds remaining: " +  millisUntilFinished/ 1000);
            }
            public void onFinish() {
                nTimeLabel.setText("done!");
            }
        }.start();
    }
