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: http://code.google.com/p/openintents/wiki/CryptoIntents 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.

Anyone can upload signed apps to the Market

Well­defined API for inter­process communication

11. Intents & the OpenIntents Project
Intents combine capabilities of multiple apps

Smart­phone application mashups!

OpenIntents:

A hub for open source Android applications

Focus on application inter­operability

Create re­usable ”Intents”

Bring open­source concepts to the way applications

on your phone interact.

12. Development:
Java, Eclipse, Debugger,
Emulator, User Interfaces,
and SQLite

13. Crypto Intent
(The nerdy program I wrote)
Translation: Encryption is the
reason you can't understand
a word I'm saying.

14. Collaboration

15. Android Ventures
Open source is not inconsistent with ventures

You can write closed­source apps for Android

All Market apps are currently free, but this will change

Might be interested in starting some kind of venture


16. Social Entrepreneurship
Social Businesses compete in the
marketplace with all other
competitors but are inspired by a set
of social objectives.

17. Meditation Words:
Sell Android Apps &
Donate the Proceeds

18. Getting Involved in Android
