Trying using Google Drive Android API as described. But some strange error occurred: GooglePlayServicesUtil(3662): Internal error occurred. Please see logs for detailed information.
Previously I had create Client ID for Android application in Google Console with SHA1 of my Eclipse (Prefs → Android → Build) and my package name com.example.googlecloudbuffer.
May be shoild I use somehow a genereted CLIENT ID or something else?
The problem was in Google API Console. You must add a Email and Product name as described.
