I confirm that with the last github changes jWindowManager run well in Android 10, congratulations!, but i see a regretion in the SetFocusable implementation, my last change look more ugly because i evited use the boolean parameters and divide it in 2 java method SetFocusable and SetNotFocusable because when i use the boolean parameter the app crash, maybe for some error in my pascal wrapper function, so now the app crash when i call SetFocusable function, @jmpessoa can you make a revision in that function?, thanks a lot.
