Google I/O 2009 - How Do I Code Thee? Let Me Count the Ways

Dan Morrill

The primary way to develop apps for Android is using managed code that runs in the Dalvik virtual machine. Yet, Android also includes a super-modern Browser that includes Gears. It’s even possible to build parts of your apps in native code (that is, C.) Choice is good, but it does mean one more decision for the developer to make — and in this case, a big decision. Should you write your app in managed code, to integrate cleanly and seamlessly with the system? Should you write your app in the Browser as “Ajax plus”, so that it can run on multiple phone platforms? Or should you go for raw speed, and write part of it in ARM-processor native code? There’s no universal answer to these questions, but in this session Dan Morrill will teach you to pick the technique that works best for your app. In this session, you’ll get a demonstration of each technique, and learn how to apply them to your own apps.

Google I/O 2009 - Offline Processing on App Engine: a Look Ahead

Brett Slatkin

App Engine was designed to run request-driven web applications, although this will change in the coming year with the release of a number of offline computing components. In this session, we’ll explore the task queue/executor model of computation and some of the more interesting applications.

Google I/O 2009 - GWT Can Do What?!?! A Preview of Google Web Toolkit 2.0

Bruce Johnson

One of the nicest things about working on an open source project is the atmosphere of community collaboration and brainstorming that it fosters. The GWT engineering team has been listening hard to the community about how GWT can be improved, and we’re excited to take you on a tour of the powerful new features that have resulted. GWT 2.0 contains huge improvements, including dynamic script loading, a new catalog of compiler optimizations, and a new approach to hosted mode debugging that promises to revolutionize your productivity. Without a doubt, it will change the way you use GWT.

Google I/O 2009 - Building Scalable, Complex Apps on App Engine

Brett Slatkin

Creating relatively simple applications that scale with App Engine can be easy after the initial learning curve. But larger applications with more complex functionality are still hard to get right, especially when you need to scale. This talk will go over more advanced data structures and techniques to use when building complex web applications with Google App Engine, and how to make them scale.

Google I/O 2009 - The Softer Side Of Schemas - Mapping Java Persistence Standards To the Google App Engine Datastore

Max Ross

Google App Engine is a powerful cloud-computing platform designed to help developers more easily create and manage scalable web applications. With the recent addition of Java support, developers can now interact with the Google App Engine datastore using JDO and JPA, both standard Java persistence APIs. In this talk we will discuss how these standards allow you to create a “soft schema” on top of a schema-less datastore, and the advantages this soft schema provides. We will also explore how the datastore’s “pre-sharded” transactional model is exposed in these standard interfaces. Finally, we will discuss how a soft schema maps to a traditional, relational schema, and examine some techniques for porting persistence code on and off App Engine.

Google I/O 2009 - Building Applications with Google APIs

Ray Cromwell

Google offers a wide variety of APIs in many domains that together form a complete platform, from authentication and authorization, cloud computing, and social networking, to visualization, mobile computing, and Google Web Toolkit. In this talk, we will walk though a complex application that integrates many APIs together, how each can solve a different need in your application, how you can share code between GWT, Android, and App Engine, and how you can monetize your application with Google Checkout.
