Periodically fetching data (polling) from the server in Android

Question

I working on the app where I get the data from the server using rest call and add it to the view. I get all the initial data correctly. I use AsyncTask for doing it.

You can checkout the AlarmManager class to do it.

Intent intent = new Intent(this, MyAlarmManager.class);

long scTime = 60*2000;//2mins

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + scTime, pendingIntent);

here's the alarm Manager--

public class MyAlarmManager extends BroadcastReceiver {

    Context _context;
        @Override
        public void onReceive(Context context, Intent intent) {
            _context= context;
            //connect to server..

        }
}

when ever the AlarmManager is 'fired' connect to the server again and populate the data you just recieved.
