My question is can i use more than 3 Pages (MainPage, Page2, Page3)? Because in the sample always define the reference of the Page with AS B4XMainPage, B4XPage2 or B4xPage3.
Thank you very much. Sorry i am so stupid. After reading another time the documentation I found the solution. I have to add a new class and after this i can refer to this class. Sorry but i am a beginner!
