Google Cloud Endpoints Setup Trouble

Question

I'm completely new to Google's Cloud Platform and I'm having trouble setting it up for my Android device. I am attempting to follow this tutorial and I'm at the point of trying to test my backend with my Android Emulator. The emulator, however, gives me this message after 20 seconds, Where instead it should say my name. Here's my code so far:

MainActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    buildUI();

    new EndpointsAsyncTask().execute(new Pair<Context, String>(this, "Solomon"));


}

EndpointsAsyncTask.java

public class EndpointsAsyncTask extends AsyncTask<Pair<Context, String>, Void, String> {
private static MyApi myApiService = null;
private Context context;

@Override
protected String doInBackground(Pair<Context, String>... params) {
    if(myApiService == null) {  // Only do this once
        MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(),
                new AndroidJsonFactory(), null)
                // options for running against local devappserver
                // - 10.0.2.2 is localhost's IP address in Android emulator
                // - turn off compression when running against local devappserver
                .setRootUrl("http://10.0.2.2:8080/_ah/api/")
                .setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
                    @Override
                    public void initialize(AbstractGoogleClientRequest<?> abstractGoogleClientRequest) throws IOException {
                        abstractGoogleClientRequest.setDisableGZipContent(true);
                    }
                });
        // end options for devappserver

        myApiService = builder.build();
    }

    context = params[0].first;
    String name = params[0].second;

    try {
        return myApiService.sayHi(name).execute().getData();
    } catch (IOException e) {
        return e.getMessage();
    }
}

@Override
protected void onPostExecute(String result) {
    Toast.makeText(context, result, Toast.LENGTH_LONG).show();
}
}

All Help is appreciated!

EDIT: Part of the problem was that I was running Endpoints Backend rather than the App Engine Servlet Backend. But now I'm now getting "connection refused" and I am running the App Engine Servlet Backend. Any Ideas?

After a tough few days, i found that the problem was that I needed to change my rootUrl from http://10.0.2.2:8080/_ah/api/ to my appspot domain. Now I'm getting the Hello World message.
