Renaming package and version names of Android project in eclipse

I have an Android project created in eclipse. I want to slightly modify this(pa开发者_如何学编程ckage names,etc) and make another app. I want both apps to be installed on phone. How to take care of versioning an app name. How should I go about renaming package and project names?

To simply rename an android app you can do that by these two steps:

(1) Right-Click on your project folder in Eclipse and go to Refactor > Rename, and make sure to update references.

(2) Edit res/values/strings.xml and change the value of app_name to whatever you want to rename it to.
