Few more newbie questions

[f4u5t]

1. where is DirInternal actually stored on my phone?

2. how are multiple screens handled? I have multiple layouts that I can call, but when the back button is pressed it exits the app instead of recalling the previous layout.
Do I need logic to catch the bacbutton, or im I going about it incorrectly?

You should use multiple activities for screens. The back button will be handled automatically.
