06 Isaac Potoczny-Jones: Open, Mobile, and Linux: A basic introduction to Android G1 development


Published on

Android is a Linux-based open source operating system by Google that can be used to power smart phones like TMobile's G1. It's a very open platform, and easy to develop software for. Isaac will give an overview of the development environment and highlight some key features of the operating system with a focus on what makes the open nature of the Android so powerful.

Isaac will illustrate these topics by giving a brief overview of the encryption system he and others have been building into Android:

For programmers, this talk will aim to be an effective introduction to Android so that you can go home, install the development tools, and start hacking even if you don't have a phone. For non-programmers, this talk will aim to give you a taste of how open-source principles will soon affect a cell phone near you.
