Install and setup Compatibility Package

Install and setup Compatibility Package -

Compatibility Package is a static library that exposes the same Fragments API from Android 3.0, so that applications compatible with Android 1.6 or later can use fragments to create tablet-compatible user interfaces.

Before you can apply Compatibility Package on your project, you have to prepare something first:

- First of all, make sure you have installed Compatibility Package:
In Eclipse, click Window -> Android SDK Manager, scroll down to Extras, install Android Compatibility package.


- Include Compatibility Package in your Build Path:
Right click on your project in Package Explorer, -> Properties.
Select Java Build Path tab on the left.
Click Add External JARS button on the right.
Browse to select your instaled android-support-v4.jar, and click OK.


Now you should have android-support-v4.jar in your Java Build Path, click OK.
