Application in the background: Android 10 specific case

From Android 10, it is no longer possible to open a window when the application is in the background.

DatePicker can open a window. If this function is used while the application is in the background, a fatal error will occur.

Tips:

It is possible to determine if the application is in the background using InBackgroundMode.
If an application needs to interact with the user while it is in the background, the solution is to display a notification (via the Notification type). When the notification is clicked on, the application will be brought back to the foreground if ..ActivateApplication is set to True. It is also possible to open a window from the procedure passed to ..ActionClick.

See Android 10: Behavior of applications in the background for more details.
