title: Delete an app's data folder in /data/data without root or factory reset?
body: <p>I am having the [INSTALL_FAILED_UID_CHANGED] problem detailed <a href="https://stackoverflow.com/questions/16277422/android-install-failed-uid-changed">here</a>.  The answer suggests deleting the <code>/data/data/package.name</code> folder because remnants of a previous installation are still lingering.  The problem is, I don't have root on the phone I am using so I don't have permission to delete that folder.</p>
