PhoneGap: Unfortunately phonegapExample has stopped

Question

I am using the latest version of PhoneGap. I am using their code, modified only the App Name and when I run it on the emulator I am getting this error: "Unfortunately phonegapExample has stopped".

My LogCat:

I am using their code, modified only the App Name

If you only change the name in the manifest:

android:name="Tasker"

You will see these errors. You need to rename the class that android:name points to as well:

public class Tasker ... {
//     This: ^^^^^^ must match the manifest

(You will need refactor the file to change the file name too.)
