Google App Engine

Tutorial: Adding a cloud backend to your application with Android Studio

Wednesday, June 26, 2013

Google Cloud Messaging for AndroidGoogle App Engine
Preliminary setup

Download Android Studio if you haven’t done so already and set it up.

Make sure you have an application project set up in Android Studio. You can use any working app that you want to integrate with your backend, even a sample app.

If you'll be running the app on an emulator, download the Google APIs Addon from the SDK Manager and run your app on that image.

Create a Google Cloud Platform project: In the Cloud Console, create a new project (or reuse an old one) and make note of the Project ID. Click on the words “Project ID” on the top left to toggle to the Project Number. Copy this as well.

Enable GCM and obtain API Key: In the Cloud Console, click on APIs and turn on the Google Cloud Messaging for Android API. Then, click on the “Register App” button on the top left, enter a name for the app, then select “Android” and “Accessing APIs via a web server”. In the resulting screen, expand the “Server Key” box and copy the API key.

1. Generate an App Engine projectAndroid app moduleToolsGoogle Cloud EndpointsCreate App Engine Backend

An App Engine project which contains the backend application source

An endpoints module with a RegisterActivity class, related resources, and client libraries for the Android app to communicate with the backend

A Google Cloud Endpoint (DeviceInfoEndpoint.java, auto-generated from DeviceInfo.java) that your Android app will “register” itself through. Your backend will use that registration info to send a push notification to the device.

A sample endpoint, MessageEndpoint.java, to list previously sent GCM messages and send new ones.

A starter web frontend application (index.html in webapp directory) that will show all the devices that have registered with your service, and a form to send them a GCM notification.

endpoints module

A RegisterActivity.java class that, when invoked, will go through the GCM registration flow and also register itself with the recently created backend through DeviceInfoEndpoint.

Client libraries, so that the application can talk to the backend using an object rather than directly using raw REST calls.

XML files related to the newly created activity.

mimic is a regular Python App Engine app, which serves as a development server (similar to the App Engine SDK "dev_appserver"), but which runs in the production App Engine environment, providing you access to the production APIs and environment while still offering a quick and easy way to test out bits of code.

bliss is a trivial browser-based code editor which lets you edit code in the mimic virtual file system (backed by the App Engine datastore), providing you with a user interface so you can see what the mimic app can do for you.

Cube Slam meets Google Cloud Platform

Wednesday, June 12, 2013

Cube Slam

WebRTC - WebRTC, a free, open project that provides Real-Time Communications (RTC) capabilities via simple Javascript APIs is built right into Chrome and other modern browsers (no plug-in required!). Cube Slam uses WebRTC to transmit a live audio and video feed from your opponent’s webcam, so you can see and hear your opponent react as the game unfolds.

WebGL - Using a combination of WebGL and the three.js JavaScript library, Cube Slam provides smooth, responsive, and fast rendering of 3D graphics.

Google Cloud Platform - The game is hosted by a scalable, high performance back end written in Go and served by Google App Engine. A STUN/TURN server running on Google Compute Engine is used to exchange data across and between firewalls.

In order to overlay our user interface (player, menu, etc) on top of Google Apps we built a Chrome Extension. The extension is written in Javascript, using standard browser APIs, jQuery and Google Closure. Specifically, our templates for the HTML parts are using Closure Templates and Javascript is compiled with Closure Compiler.

Bridging Mobile Backend as a Service to Enterprise Systems with Google App Engine and Kinvey

Wednesday, June 5, 2013

The following post was contributed by Ivan Stoyanov, VP of Engineering for Kinvey, a mobile Backend as a Service provider and Google Cloud Platform partner. Kinvey helps individual and enterprise developers dramatically reduce the time and cost of developing and maintaining a backend for their native and HTML5 mobile apps. Backend as a ServiceIncreasingly Complex RequirementsBusiness Logicnode.jsmessage triggersaccessing third party APIs

The APIs are highly asynchronous. For many developers this is not a problem, but for a growing number of them, the execution flows are confusing and the complexity beyond a single page of code gets very high.

Code is limited to a single language - JavaScript. Android developers, for example, are much more comfortable in Java territory, as are enterprise web application developers.

Only Kinvey-approved modules are allowed.

Get your mobile application backed by the cloud with the Mobile Backend Starter

Monday, June 3, 2013

(cross-posted on the Android Developers Blog)PulseSongPop Mobile Backend StarterMobile Backend StarterGoogle Cloud Messaging

Cloud data storage: Users change devices and increasingly use multiple devices. Store any amount of data per user in the cloud to be accessed from anywhere.

Pub/Sub messaging: Send messages from one device, to any or all other devices. You can easily use 1:1 and 1:many messaging as well as broadcasting. This feature is useful for various applications including social apps, forums, chat, gaming, and group collaborations.

Push notifications: Data updated on one device is automatically available on all devices with GCM for Android.

Continuous queries: Create queries that run continuously on the server, automatically feeding updates to the client. These queries are powered by Prospective Search.

Google authentication and authorization: Keep data isolated per user or shared among users.

Free to get started, scales effortlessly with your needs: You can start by handling hundreds of users for free, then grow to any scale.

Quick setup and integration

First, go to the http://cloud.google.com/console, and create a project. Then click deploy.

Click on settings to go to the admin panel for your new backend. Under "Authentication / Authoirzation" select "Open (for development use only)" and save the changes.

Next, download the Android client project and open it up in your Android IDE. Locate the Consts.java file and set the PROJECT_ID to the Project ID you created in the Google Cloud Console.

Now just build and run the Android application and you have a cloud enabled Android application

Check out the complete docs for details on setup and to find out how to enable authentication, send push notifications, and use standing queries. The best part is you can download the complete source code of the backend on GitHub and customize it to meet your needs.

See Mobile Backend Starter in action at Google I/O

To see Mobile Backend Starter in action, check out our talk at Google I/O 2013 (embedded below) called "From Nothing to Nirvana in Minutes: Cloud Backend for Your Android Application." The talk shows how to use Mobile Backend Starter to create a new backend server and integrate it with an Android app via Google Cloud Endpoints and the Google Plugin for Eclipse. We look forward to hearing your questions and learning about the amazing applications you have built. You can find us lurking on the Cloud Endpoints StackOverflow forum. - Posted by Brad Abrams, Product Manager
