I'm using Google API to open a file picker and select a file from Goolge Drive. It works but I've got a strange problem about application grants. If I load a file from Google Drive app, I can't select the files (it's gray) but if I upload the file from the web interface of Google Drive, then I can select the file. Can I do something to have the grant on those files? Is it a bug?
PS: I load the file on my phone via Google Drive app but opening the file via Dropbox because when I select "Upload" from Google Drive app I can't select a file browser app.
