i'm a total beginner in Android developing but i have a few experience with java.
i'm learning android developing at the moment with the Tutorials of and im writing my new App now.

i got a main activity now with a button "Gallery" and a gallery activity.
Now i want to make a Gallery inside the ativity for the first. Just to understand a little bit how to create gallerys.
at the moment i am at the Saving Files part, and i read that there are two file Storage areas. internal and external Storage
so i dont know whitch one is the better one for my app because i have a Galaxy Nexus and it just got a internal Storage
but i read that.
Internal storage is best when you want to be sure that neither the user nor other apps can access your files.
so i dont know which one to use and the other thing is, that the file is outdated so how do i create
gallerys for android 4+

and i'm sorry for my bad english^^
