I'm developing an app that I use to check data of medical devices. The first realese can store the data in separated csv files. Now I'm tring to store data in Google sheet and now I can't find any file on the device directory, same app without the gsheet implementation works fine. I think it's dipend on permissions, istalling the apk, Android didn't ask to autorize the access to the local storage. May someone have any idea to have at the same time both tipy of storage?
