So, I have nearly 20 Activities because I have nearly 20 Layouts in which are important information (concerning the app content). Well, I have to say in these Activities are mostly TextViews.
Is there something like a "Stack" where Activities can be put? If there is a stack, does it affect the perfomance when running the app? How can I see this stack?
Is there a rule of how much Activities an App should have or does it depend on what the purpose of the App is?
It would be nice if you can explain me how the Activities are held or how they are handled when I run my app. Because I do not want that these 20 Activities to affect my performance.
