Pause and Continue CountDownTimer in Android

I know there are a lot of threads with the same topic, but I do not want to use some random code I do not understand.

This is my current code to pause and continue a CountDownTimer in Android Studio:

public void getReadyTimer(long time){
    time = 12000;
    progress=0;
    circularProgressBar.setProgress(0);
    //tvInfo.setText("Get Ready!");

    timer= new CountDownTimer(time, 1000) { 

        public void onTick(long millisUntilFinished) {
            milliLeft = millisUntilFinished;
            sec = ((millisUntilFinished-1000)/1000);
            tvTimer.setText(Long.toString(sec));
            //tvTimer.setText((millisUntilFinished-1000) / 1000 + ""); 
            progress++;
            int animationDuration = 1500; // 2500ms = 2,5s
            circularProgressBar.setProgressWithAnimation((int)progress*100/(11000/1000), animationDuration); 

            circularProgressBar.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if (t== 0) {
                        pauseTimer();
                        t =1 ;
                        tvInfo.setText(Integer.toString(t));
                    }else{
                        resumeTimer();
                        t = 0;
                        tvInfo.setText(Integer.toString(t));
                    }
                }
            });

        }

        private void pauseTimer(){
            timer.cancel();
        }

        private void resumeTimer(){
            Log.i("sec", Long.toString(sec));
            milliLeft = sec*1000;
            getReadyTimer(milliLeft);


        }

        public void onFinish() {
            if (circularProgressBar.getProgress() == 100) {
                startTimer();
            }
        }

    }.start();
}

However it does not work properly. The problem is, that the Timer (after pausing) starts again with the value "time" and not with "millileft" as it should be. I appreciate every kind of help.

Use this, may help you

Global Variables 

private CountDownTimer timer;
long time = 12000;

Timer

private void startTimer(long timerStartFrom) {
    timer = new CountDownTimer(timerStartFrom, 1000) {

        @Override
        public void onTick(long millisUntilFinished) {
            //updating the global variable
            time = millisUntilFinished;

        }

        @Override
        public void onFinish() {

        }
    }.start();
}

In Initial(onCreate)

How to Start

start your timer with

startTimer(time) as time has initial value //12000

How to Pause

then you can pause/cancel timer by using timer.cancel()

How to Resume

and when you want to resume just start your timer by calling startTimer(time) as the timer has the updated value.

What will it does it will start your timer with previous time where you have stops your timer

Simple, Happy coding :)

You are re-assigning the value of the passed parameter milliLeft to 12000. To fix this you can create two methods. One which accepts a parameter and the other without. e.g.

public void getReadyTimer() {
    this.getReaderTimer(12000L); // default value
}

public void getReadyTimer(long time) {}

In the parameterized method remove the assignation of

time = 12000;

You shouldn´t call timer.cancel() to pause the timer. And afterwards you can call timer.resume() to start it again. There is no need to use so "complicated" logic.

Have a look here: Android: timer start, pause, stop
