google maps using phonegap in android

I want to display the maps in android using phonegap. I copied the code shown in http://wiki.phonegap.com/w/page/16494764/PhoneGap-Geolocation-Sample-Application. I a开发者_JAVA技巧m using phonegap.0.9.4 and android emulator 2.2. I tested the application in android device. It is every time calling the fail method. Can any one tell me what the problem is or tell me where I can get a working application for displaying maps?

An Android PhoneGap maps tutorial is here.

An even more fully featured open source maps app is available on the Android Market here.
