Android Question Confused with notifications, when phone is sleeping...

[Olli73]

Hello, I have an older App, build with the "old" activities and Services. On newer Android Versions I have the problem, that the notifications are not shown then expected...

If the App is on the screen, everythink is ok. But if the Phone go sleeping, I got the problems.
What is the best way now to Show a notification or make a beep, when the Phone is sleeping? I try to log the receiver_receive Event in the Service, which should Show the notification. But it seems, that the receiver Event is not fireing. I dont found a sample code in the forum, till now.

1.FB receive message
2. Start another Service, which do something in background, by StartReceiver
3 . After background work, start the next Service to Show a notification on screen or make beep to inform the user. Also by calling StartReceiver (or can I use her the old way: StartService?
