I usually write this code to start a service with AlarmManager
.
intent = new Intent(getActivity(), someservice.class);
pendingNotificat
This is how you can do it:
1.) Define a static intent (intent1) and use it to pass to AlarmManager when setting time. So now when ever time, will lapse; AlarmManager will notify by sending intent1.
2.) On onReceive of BroadcastReceiver of intent1, start a AsyncTask. At end end of AsyncTask, set the next time for AlarmManager.
Based upon munish-katoch's response, I have the following concrete solution.
Set an alarm:
Intent intent = new Intent(context, AlarmReceiver.class);
PendingIntent alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
AlarmManager alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
alarmMgr.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime() + 5 * 1000, 60 * 1000, alarmIntent);
The above code configures AlarmManager
to fire at AlarmReceiver
, which is defined as follows:
public class AlarmReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
new MyAsyncTask.execute();
}
}
In the event of an alarm AlarmReceiver
starts MyAsyncTask
.
There are life cycle issues associated with instantiating an AsyncTask
from a WakefulBroadcastReceiver
, i.e., the above solution can lead to MyAsyncTask
being killed prematurely. Moreover, threading rules are violated.
