App Folder files not visible after un-install / re-install

Question

I noticed this in the debug environment where I have to do many re-installs in order to test persistent data storage, initial settings, etc... It may not be relevant in prod

Answer 1

It looks like Google Play services has a problem. (https://stackoverflow.com/a/26541831/2228408) For testing, you can do it by clearing Google Play services data (Settings > Apps > Google Play services > Manage Space > Clear all data).

Or, at this time, you need to implement it by using Drive SDK v2.
