Which method is best?

Question :2 => How to find a service is running or not programmatically?

Solution

  • Write a BroadcastReciever to receive the ON_BOOT broadcast (you'll need to add appropriate permission and intent filter to your manifest). The BroadcastReceiver exists only to create a 9 am notification with the Alarm Manager. The scheduled alarm has a PendingIntent which will launch the service. Obviously, set the Alarm to repeat every 24 hours.

    When launched, the service simply runs normally until 4 pm, at which point it stops itself.

    The service's onStartCommand() method should return the appropriate flags to cause the system to restart it if it crashes or gets killed.

    The only thing I can't figure out is how to auto-start the service the first time it's installed. Waiting for the device to be rebooted isn't very practical. When I write apps like this, they're typically combined with an Activity that has controls to start and stop the service.
