Mobile Backend Starter does not work “out-of-the-box”

Question

I'm trying to test the Google App Engine - Mobile Backend Starter which I have deployed the backend and the admin is accessible.

The problem is in the Android client which throws this error when trying to send a message from the client:

I don't understand what is Not Found here? I mean I am sure I have typed the PROJEC_ID properly.

Answer 1

I/CloudBackend(675): com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found

A 404 not found means it's doing a HTTP request to an address that is wrong / doesn't have a website.

So I'm guessing that you're supplying the wrong URL somewhere during your setup?
