Howtoforge posted a tutorial about setting up an Android App Build Environment with Eclipse, Android SDK, PhoneGap on Ubuntu 10.10

This tutorial describes how you can set up an development environment for building Android apps on an Ubuntu 10.10 desktop using Eclipse, the Android SDK, and PhoneGap. I will describe how to build Android apps from the command line with PhoneGap and from the GUI with Eclipse and PhoneGap and how to test them in an Android emulator and on a real Android device. PhoneGap allows you to develop your Android applications using web technologies such as HTML, CSS, and JavaScript (e.g. with JavaScript libraries such as jQuery/jQTouch), and it will turn these web apps into native Android apps (in fact, PhoneGap supports multiple platforms such as Android, iPhone, Palm, Windows Mobile, Symbian, so you can use the same sources to create apps for multiple platforms).
