Apps Changing a Package Name

[androiddevloper]

I am new to android development and could use some help.
You see, I have been working on an android application for a few months and now need to change the package name. So I went into AndroidManifest.xml and changed the package name, but all it did was create errors.

So my question is:
How do you change the package name of an application in Eclipse?

1. Open project
2. Navigate to the src node in the Package Explorer tab
3. Right-click on the package name that's above your source .java files and select Refactor and then Rename...
4. Enter your new package name and click the OK button.

That should be it!
