Sign out google user from android app

Question

I have been able to authenticate users from android app to my app engine site using this blog post; http://blog.notdot.net/2010/05/Authenticating-against-App-Engine-from-an-Android-app

For the first login; permission dialog appears. And after allowing the app the user is authenticated. How can i sign out this user? How can i remove the granted permissions?

Answer 1

You can't. It is only removed after you uninstall the app. So if this is for testing, re-installing will do. Otherwise you just have to live with it.

Answer 2

if you want to revoke permission for one app, you must enter your account setting on web, then security->access manage. This's my favorite way. some link likes: https://www.google.com/settings/u/1/security
