"Phonegap is a cool set of tools (which I am about to try out for the first time) which lets you build applications in HTML / Javascript for Android and iPhones. I had some trouble installing out of the box on Ubuntu 9.10 (Karmic), so I thought I’d document my fix."
This tutorial provides instruction on setting up PhoneGap for your web application on the Android G1.
For information on setting up the Android SDK, see the Android Developer Documentation. In general, you will need to download the Android SDK (remember where you put it!), and set up certificates to sign your applications.
For information on using Eclipse, please see the Eclipse website.
PhoneGap is an open source development framework for building cross-platform mobile apps. Build apps in HTML and JavaScript and still take advantage of core features in iPhone/iTouch, iPad, Google Android, Palm, Symbian and Blackberry SDKs.
