Do you have downloaded the library?
- If not, download it and extract the actual library project folder. (it just looks like any other Android project folder you might have seen)
- Import it into your Eclipse workspace. (it will then just look like any other project in your workspace explorer)
- Then right-click on your project and go to properties.
- Select "Android" and press the "Add" Button on the bottom of the window.
- Select your desired library.
- Thats it.
