How to run an async task for every x mins in android?

You can use handler if you want to initiate something every X seconds. Handler is good because you don't need extra thread to keep tracking when firing the event. Here is a short snippet:

private final static int INTERVAL = 1000 * 60 * 2; //2 minutes
Handler mHandler = new Handler();

Runnable mHandlerTask = new Runnable()
{
     @Override 
     public void run() {
          doSomething();
          mHandler.postDelayed(mHandlerTask, INTERVAL);
     }
};

void startRepeatingTask()
{
    mHandlerTask.run(); 
}

void stopRepeatingTask()
{
    mHandler.removeCallbacks(mHandlerTask);
}

Note that doSomething should not take long (something like update position of audio playback in UI). If it can potentially take some time (like downloading or uploading to the web), then you should use ScheduledExecutorService's scheduleWithFixedDelay function instead.


Use Handler and PostDelayed:

final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
    public void run() {
        readWebpage();
        handler.postDelayed(this, 120000); //now is every 2 minutes
    }
 }, 120000); //Every 120000 ms (2 minutes)
