title: Sign in to AppEngine web application from an Android client application
body: <p>I'm writing an Android application that I want to be able to send requests to a Google App Engine application.  In order to do this, the Android app needs to authenticate the user (should be able to just use their Google Account).  I'm not sure I'm doing it right, but this is the only way I've found so far:</p>
  
  <ol>
  <li>Post email, password, etc. to https://www.google.com/accounts/ClientLogin</li>
  <li>Obtain an authorization token from the aforementioned address</li>
  <li>Use the authorization token in the header of the requests to the AppEngine application</li>
  </ol>
  
  <p>But this isn't working (users.get_current_user() still returns None).  Is there a right way to do it?</p>
