Google OAuth2 re-authorization is missing permissions on the consent page

Question

When I force a user to re-authorize my application a second time, using approval_prompt=force, how can I get Google to show the user the entire list of permissions

Answer 1

You have to revoke the access token and log out. Then if you go to sign in process, It will show the permission.

public static void RevokeAcess(String accessOrRefreshToken) throws ClientProtocolException, IOException
{
    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost("https://accounts.google.com/o/oauth2/revoke?token="+accessOrRefreshToken);
    client.execute(post);
}

This network process should be called in non ui thread or asyntask
