BroadcastReceiver to send notification and update ui if activity, active

I have an activity which just displays a daily counter. When the day ends, i want to send a notification with last day counter, insert it in a db and if the app is running update the counters label to zero.

I think i must register a static <receiver>android.intent.action.DATE_CHANGED</receiver>. so as to get notified even if the activity is not running. There I insert the value in DB and i send the notification.

And a dynamic created broadcast receiver which i will unregister onPause, which receives the same events, but it will only update the UI and specifically the label.

Is this the best solution?

Is there any way from a broadcastReceiver to make my Activity (if is running) to go to resume again ? Is it possible from broadcastReceiver to call a Service, which will update my UI if my Activity is running?

Solution

  • After more reading i found that the best solution is the above.

    A static broadcast receiver for DATE_CHANGED actions. This will start a Service which will update the db and send a local custom broadcast (com.myBroadcast.WakeUpActivity) The Activity if is running will register a receiver for the previous custom broadcast (will unregister onPause), and will update the UI.
