Google IO 2009: Mobile

I, like many 10-5 developers not working directly with ajaxified web 2.0 applications, was not able to go to the Google I/O conference. I don’t feel so bad not going since Google has just released video recordings of over 80+ technical presentations from Google I/0. Most of the technical presentations are pushing Google’s APIs such as Android, Google App Engine, GWT, and Open Social.

As an aid for myself, and maybe other GWT developers, I have organized the pertinent Android and mobile talks as follows…

Turbo-charge your UI: How to Make your Android UI Fast and Efficient
Learn practical tips, techniques and tricks for making your Android applications fast and responsive. This session will focus on optimizations recommended by the Android framework team to make the best use of the UI toolkit.

Supporting Multiple Devices with One Binary
The Android platform is designed to run on a wide variety of hardware configurations. Learn how to take advantage of the application framework to make your application run on a wide variety of devices without having to build a custom version for each.

Coding for Life — Battery Life, That Is
The three most important considerations for mobile applications are, in order: battery life, battery life, and battery life. After all, if the battery is dead, no one can use your application. In this session, Android engineer Jeffrey Sharkey will reveal the myriad ways — many unexpected — that your application can guzzle power and irritate users. You’ll learn about how networking affects battery life, the right and wrong ways to use Android-specific features such as wake locks, why you can’t assume that it’s okay to trade memory for time, and more.

A General-purpose Caching Architecture for Offline-capable Web Applications with HTML 5 Databases or Gears
Puzzled by all the new architectural choices possible when trying to build an offline-capable web application? So were we until we decided to design the newly launched Gmail Mobile Web for iPhone and Android’s offline capabilities by analogy with microprocessor caches: offline via a portable write-through caching layer running on either HTML 5 or Gears databases.

Mastering the Android Media Framework
Some monks might take a vow of silence, but Android certainly hasn’t. Attend this session, and help your app find its voice. Android engineer David Sparks will explore the multimedia capabilities of the Android platform, lifting the covers on the infrastructure to show you how it works and the right (and wrong!) ways to use it. You’ll learn how things work under the hood, how to dodge the common media-related developer pitfalls, and how to write secure and battery-efficient media code.
