You do not need to copy or create anything manually on your Android device. When you install the app, it takes care of everything automagically.
And my apologies about where the directory is. I was thinking of some other bits when I responded last night (just before going to bed). I'm usually much more careful about that kind of thing.
On the android, it will use the com.mycompany.mygame directory.
Again, you do not have to manually do anything to set/create directories.
When your app runs, if you create a file, the AppGameKit stuff takes care of creating any directory indicated (media or whatever) in the application data area (the same setup used by all Android apps that generate files).
As long as you use the exact same name for the file generated (case counts) as well as any directory you specifically indicate, the created file can be accessed without doing anything else.
So if you download an image from a site, it should be available where you told it to go.
