Android Code Snippet Back to edge-to-edge with B4A Ver13.4 and SDK 35

Dear Erel has disabled the edge-to-edge feature in the new version he released (B4A 13.4 - resources 7.25). This will be a great help for developers who don't want their page layout to be cluttered. But for me, who loves edge-to-edge, there needs to be a way back. I found it from Erel's codes and I summarized it as following:

Important: It is assumed that you are using SDK 35 or 36.

To do this, simply remove this line from the manifest:

CreateResourceFromFile(Macro, Themes.LightTheme)

And instead, put a template from Google itself, something like this:

SetApplicationAttribute(android:theme, "@android:style/Theme.Material.Light")

It will be edge-to-edge, but the toolbar is still there. If you want the toolbar to move away, add this event to the main file:

Sub Activity_WindowFocusChanged(HasFocus As Boolean)
    Log(HasFocus)
    If HasFocus Then
        Try
            Dim jo As JavaObject = Activity
            Sleep(1500)
            jo.RunMethod("setSystemUiVisibility", Array As Object(5894))
        Catch
            Log("setSystemUiVisibility did NOT work!")
        End Try
    End If
End Sub

and call it at the beginning of Sub Activity_Create like this:

Sub Activity_Create(FirstTime As Boolean)

    Activity_WindowFocusChanged(True)
  
    Dim pm As B4XPagesManager
    pm.Initialize(Activity)

End Sub

The line "Sleep(1500)" is for the toolbar to go away with a delay so that the user can see it go away and understand where to bring it back. The delay can be adjusted as desired.
