GoogleAuthException: Unknown when authenticating with Cloud Endpoints

Question

I\'m trying to add authentication to my Cloud Endpoints, but I can\'t get it to work. I\'m using this blog as a guideline: http://devthots.blogspot.nl/2012/07/building-awesome-a

Answer 1

Using

GoogleAccountCredential credential = GoogleAccountCredential.usingAudience(MainActivity.this, "server:client_id:12312312312-abcdefghijklmnopqrstuvw012345678.apps.googleusercontent.com");

and

@Api(name = "noteendpoint", clientIds = { Ids.WEB_CLIENT_ID,
        Ids.ANDROID_CLIENT_ID }, audiences = { Ids.ANDROID_AUDIENCE }, namespace = @ApiNamespace(ownerDomain = "example.com", ownerName = "example.com", packagePath = "test"))
public class NoteEndpoint {

    public class Ids {
        public static final String WEB_CLIENT_ID = "12312312312312-abcdefghijklmnopqrstuvwxyz012345678.apps.googleusercontent.com";
        public static final String ANDROID_CLIENT_ID = "12312312312312-0123456789abcdefghabcdefghabcdefgha.apps.googleusercontent.com";
        public static final String ANDROID_AUDIENCE = WEB_CLIENT_ID;
    }

solved the problem.
