A hands-on session which will demonstrate how to take an existing application and write a fully functional backend on Google Cloud Platform. We will show you how quickly you can start by using Android Studio integration with Google Cloud Endpoint and hopefully by the end of the session we will have a live backend in production that we all can use.

4. Download – Android Studio Early Access Preview:
http://developer.android.com/sdk!
Android Studio
An open-source IDE built for Android
• Based on IntelliJ IDEA with coding
assistance tools to help write Java code
• Integrated visual and layout designer
• Large number of bundled static code
analysis tools (Lint) to help build quality
apps
• Integrated with Gradle to enable one build
across dev environment (IDE, command
line, CI server)

5. Google Cloud Endpoints
Extremely simple way to build server side logic on full
power, management free Google App Engine platform
• Uses App Engine’s auto-scaling and high-availability
• Uses auto-generated, strongly typed, mobile optimized client
libraries for Android, iOS and web.
• Exposes standards based REST interfaces with built-in
authorization

9. Android Studio + Cloud Endpoints
Easiest way for mobile developers to
connect to Google Cloud Platform
• Create Google App Engine backends in
Android Studio
• Generate Java-specific bindings for use in
Android app
• Benefit from as-you-type validations and
quick-fixes when defining the backend API
• Use App Engine-specific Gradle tooling that
allows for a unified client/backend build
