You can use a Content Provider to provide access for third party apps to your internal files. This is the recommended method for sharing files across apps, and is much safer as pointed out by @CommonsWare in the comments.

If you are the one writing both apps, and they are signed with the same key, then you can also use a shared user ID to allow direct interapp access to data files.
