The following 2 references should get you started with Android, Phonegap, Jquery mobile.
- phonegap-android-eclipse-quickstart gives all the steps needed to run a phonegap application with Android and Eclipse. After building the first sample project follow closely the steps given for new project.
- UI Development using jQueryMobile gives steps to integrate Jquery mobile to the mix.
The 2nd example uses Phonegap version 0.9. Updating to the recent version of phonegap is easy. However an extra XML folder in phonegap res (as mentioned in the first reference) should also be copied!
In reference 2 the download code and the listing in the blog are different. The blog source HTML works.
