How to call method after every 20 seconds in Android

Question

I want to write an Android application which when opened call a method after 20 seconds then auto call method every 10 seconds.

Any thoughts on how to proceed?

Answer 1

You could do it with a single Handler like this:

final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
   @Override
   public void run() {
       //Do something after 20 seconds
   }
}, 20000);  //the time is in miliseconds

And to repeate the same every 10 seconds you could add the following line in the same method

handler.postDelayed(this, 10000);

Like this:

final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
   @Override
   public void run() {
       //Do something after 20 seconds
       handler.postDelayed(this, 10000);
   }
}, 20000);  //the time is in miliseconds

Please check the below code.

new Timer().scheduleAtFixedRate(new TimerTask() {
                @Override
                public void run() {
 // Enter your code
}
            }, 0, 20000);//put here time 1000 milliseconds=1 second

Hope this code will help you.

CountDownTimer cdt;

cdt = new CountDownTimer(timeint * 60 * 1000, 1000) {
    @Override
    public void onTick(long millisUntilFinished) {          
        Log.i(TAG, millisUntilFinished " millis left");
    }

    @Override
    public void onFinish() {
        Log.i(TAG, "Timer finished");
    }
};

cdt.start();
