Android Question Back to fullscreen after using the keyboard

[appie21]

Hello

I use a program that run fullscreen
I use:

Sub Activity_WindowFocusChanged(HasFocus As Boolean)
If HasFocus Then
   Dim jo As JavaObject = Activity
   jo.RunMethod("setSystemUiVisibility", Array As Object(5894)) '3846 - non-sticky
End If
End Sub

But when I use the keyboard and close it the application will not go back to full screen( the bar with the back and home button are visible) if i want close/hide the keyboard with a code

I use:

        Dim K As Phone
        K.HideKeyboard(Activity)

I add:

       Dim jo As JavaObject = Activity
           jo.RunMethod("setSystemUiVisibility", Array As Object(5894)) '3846 - non-sticky
        Activity.Height = -1
        Activity.Width = -1

But the bar in the bottom not go away
How can I fix this?
