I'm developing an app which stores few setting in two .xml files, saved on internal storage. I need to save them in there, so please don't answer me "Save them on SD-cards".

I try to uninstall an then re-install (from Android Studio) my app to see if the `android:allowBackup="true"` works also for internal stored file but the answer was no.

Is this because I done the re-install from the IDE or I need to add some code somewhere?

Thanks for help.
