Hi,
I've managed to get this to work for Google App Engine by specifying
"ah" for the service parameter, for example :
GoogleLoginServiceHelper.getCredentials(this,
54321,
null,
GoogleLoginServiceConstants.REQUIRE_GOOGLE,
"ah",
false);
This also requires permission:
com.google.android.googleapps.permission.GOOGLE_AUTH.ah
I don't like having to use undocumented API's, but I suppose it's
better than the alternative of having the user to enter their username
and password.
