07-18 13:07:49.267: W/System.err(16389): }

I have been spending 2 days to solve this error but no luck, has anybody implemented Google Drive API to access file and/or upload file?

Please need your help

You need to use a GoogleAccountCredential to authorize and authenticate your requests.

GoogleAccountCredential credential =
    GoogleAccountCredential.usingOAuth2(this, DriveScopes.DRIVE);

Drive service = new Drive
    .Builder(AndroidHttp.newCompatibleTransport(), new GsonFactory(), credential)
    .build();

service.files().list().execute();
