Android Question Activity WindowFocusChanged event.

[Tom_707]

Hi,

I'm trying to figure out the Activity WindowFocusChanged event but there doesn't seem to be much in either the B4X or Android documentation.

When you create an Activity, you add Views to it, or load a Layout. Which part of the Activity is the Window? Is it the entire screen that contains all Views?
When does the WindowFocusChanged event fire? Is it when you swap to another App that is currently running on the Android device?

Any help will be appreciated.

I don't need this event as yet, I'm just learning B4A and trying to figure out what's what.
Thanks for the reply.

You don't need this event. It is used in some rare cases. For example to enable immersive mode.

Tip: don't waste too much time with learning the activities events and life cycle. Start with B4XPages. Everything will be simpler.

I'll have a look at the B4XPages tutorial. Thanks Erel.

Starting from Android 5 (API 21) there is better support for kiosk applications. Kiosk applications = applications that the user cannot exit from. As you can see in this screenshot, the home button and recent apps button are missing. The top notifications drawer is also inaccessible. This...
