[Eclipse] Change Android application name in Eclipse

I had tried to change the application name by modified the Manefist.xml directly. But it led me a lot off error.

To fix this, I recommend you do it with the interface:

1. Right click on your project
2. Down to "Android Tools"
3. Click on "Rename Application Package"


And this is called "refactoring", that is, automatically adjust all the reference that related to your modification.

[Eclipse] Project has no project.properties file! Edit the project properties to set one.

When you import a project into Eclipse and get a error message like this:

Project has no project.properties file! Edit the project properties to set one.

To solve it, just restart the Eclipse IDE.
