[android-developers] Protecting files on non-rooted phones

2011-01-07 Thread John Gaby
I find that, when using a actual device that is not rooted, that I
cannot see the contents folders created by my application.  However,
if I know the exact name and path of a file, I CAN pull or push it
using ADB.  Is there a way to prevent external access to application
files (on a non-rooted phone, of course).

Thanks

On a user build, adb can not access any application files, with these
exceptions:

- If the app has declared itself debuggable, recent versions of android will
allow the shell user to change to run as that app uid and thus access its
files.
- If you create files that are explicitly marked as world readable or
writeable, then the shell will be able to read/write those files as
indicated.
