Handler postDelayed in Android Service

In my app there is a Service that is intended to run constantly in background once started. This service is started from an Activity and this is the onStartCommand() method:

MyService:
....

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(Intent intent, int flags, int startId)
    mHandler.postDelayed(new myRunnable(), scheduledTime);
}

I want to know if having a very big scheduledTime(lets say a couple of days in milliseconds), the Handler will still execute the Runnable? Or should I better use the AlarmManager for this?

Thanks.

Solution

  • I want to know if having a very big scheduledTime variable (lets say it represents a couple of days), the handler will still execute the runnable?

    Yes, if the service and the thread the Handler posts to will be alive by the time.

    Or should I better use the AlarmManager for this?

    Yes.
