Question

I am writing timer application (like the one we use for cooking) for android. I used CountDownTimer to decrease remaining time every second. However, because I am so new at Threads, I didn’t know there was a delay in the timer.

For example, consider simple code using CountDownTimer:

CownDownTimer timer = new CountDownTimer(60 * 1000, 1000) {
     public void onTick(long millisUntilFinished) {
         System.out.println(millisUntilFinished);
     }
}

When I run this, onTick() method should run 60 times, but it doesn’t. Instead, it runs about 57 times. I found out that this is due to delay. What is the most accurate way to write my timer application? Any suggestions? Thanks.

Answer 1

CountDownTimer timer = new CountDownTimer(60*1000, 1000) {
    public void onTick(long millisUntilFinished) {
        // TODO Auto-generated method stub
        Log.e("", "millisUntilFinished"+millisUntilFinished);
    }
    @Override
    public void onFinish() {
        // TODO Auto-generated method stub
    }
};
timer.start();

I run this code and on logcat i get 59 entries and I think 1 entry not get because when it you stat timer it wait 1000 milies for first also and then go with onTick(),so the code is working fine

Thanks
