Erro ao mudar de screen no menu


I created an android app with 6 Screens, the first is a presentation screen, the second is a login screen, the third is a Mnu screen with 3 buttons (this screen is where the error occurs), and another three loom.
When I start the app and log in, the menu screen opens and when I click on any button to go to another screen there is no problem, but when I return to the menu screen and try to open another screen the app gives an error and returns for Screen1.
Can you help me?


it probably would help to tell us, which error exactly you get?

meanwhile try to switch screens correctly… see also tip 1 here
