Android Question UsageEvents

Most of the documented methods are only available in SDK 29 (android 10).

Only a few have Android 10 as of now i guess. I don´t think there is something in B4A as of now.

Yes, that true. Some of the methods like MOVE_TO_BACKGROUND and MOVE_TO_FOREGROUND have been around since SDK 21 though (they have bee deprecated for SDK 29) It would have been a great addition to answer many questions I've read on this forum.

The usage.events functionality looks promising and will be of great use in the future when Android 10 is more popular.
