Android Question Bottom nav bar covers app from time to time

[fastlingo]

Sometimes, rarely, when the app starts the Root.height appears to be including the bottom android nav bar. Since I have a webview in full screen, the android buttons cover the bottom area. Is there anything to do about this? As it happens very rarely, it is very hard to debug.

    Root = Root1
    Root.AddView(webviews(0),0,0,Root.Width,Root.Height)

Full screen activities are sometimes resized based on the previous activity state. There is no simple solution for this. You can try to intercept this with IME.AddHeightChanged event.

same here: an app for which I've set the opt out edge-to-edge and always start correctly, sometimes, coming back from background (I suspect after some time the lock screen has been active) it appears full screen, with the bottom bar overlayed.
I classified it as an Android bug, hoping it will be solved in the next release.
This forced opt-in for edge-to-edge looks to be a false step from Google: I see every kind of app on the market (not B4A) with the nav bar overlayed and buttons underneath.

Chatgpt suggested I should use setlayoutanimated, but I don't know if it works as I can't test it.

Sub FixLayout
    ' Always anchor to Activity, not cached values
    webviews(0).SetLayoutAnimated(0, 0, 0, 100%x, 100%y)
    webviews(1).SetLayoutAnimated(0, 0, 0, 100%x, 100%y)
End Sub

Sub FixLayoutDeferred
    Sleep(1)          ' yield a frame so Android completes layout/insets
    FixLayout
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.AddView(webviews(0),0,0,Root.Width,Root.Height)
    Root.AddView(webviews(1),0,0,Root.Width,Root.Height)
    FixLayout
...


Sub resume
    CallSubDelayed(B4XPages.MainPage, "FixLayoutDeferred")
