Unable to run example of PhoneGap for Android

I tried to follow this instruction: http://wiki.phonegap.com/w/page/16494774/Getting-started-with-Android-PhoneGap-in-Eclipse

I can run the example but when I clicked on the "Beep" button or anything button, it has error in "adb logcat" like this and the app crashed:

Can someone help please? Thanks.

In case something went wrong along the project creation phase, check out http://wiki.phonegap.com/w/page/34483744/PhoneGap-Eclipse-PlugIn-for-Android The plugin described will configure and build the example automatically and should be an easier startup experience.
