Summary: Android 10, gesture control, minimize app - not expected behavior
Product: SDL Reporter: Vortelio <vortelio>

Status: RESOLVED INVALID QA Contact: Sam Lantinga <slouken>

Description Vortelio 2020-10-22 06:48:47 UTC 
There is no way to reliably catch the loss of window focus.

With the classic navigation of three buttons, if minimize the app, the following order is performed:

onPause ()
onWindowFocusChanged ()
nativeFocusChanged (false)
handleNativeState ()
nativePause ()

If gesture control is activated, the order is as follows:

onPause ()
handleNativeState ()
nativePause ()
onWindowFocusChanged ()
nativeFocusChanged (false)

You get loss of focus with the SDL_WINDOWEVENT_FOCUS_LOST, you don't need to use the java side.

But java onWindowFocusChanged() should give you the focus.
