  • Define what you mean by external storage. Do you mean a removable SD card? Then no. Do you mean external storage by the android definition (which is really just internal to the phone)? Then every app gets a private directory in external storage, and no other app can read it. Of course if they root the phone they can do it anyway, nothing can stop that. – Gabe Sechan Aug 02 '19 at 13:14
