SlidingMenu is a helpful Android library for developers. It creates a side navigation like the Facebook app but it is not easy to setup the library nor the example. Here you will find the steps to make the library and example free of errors and ready to use.

Step 1: Import the library and example
Download the library as well as the app on GitHub (https://github.com/jfeinstein10/slidingmenu). Then, unzip the file and create a new project in Eclipse. Select Android Project from Existing Code and click Next. Click Browse and choose the folder where you unzip the SlidingMenu library. Check Copy projects into workspace and click Finish. You have imported the library and example but you have an X icon next to the SlidingMenu library project and an exclamation mark icon next to the example project.

import com.actionbarsherlock.app.SherlockFragmentActivity;
Then, replace the class declaration:
public class SlidingFragmentActivity extends FragmentActivity implements SlidingActivityBase {
with:
public class SlidingFragmentActivity extends SherlockFragmentActivity implements SlidingActivityBase {
Clean and build the project if the error messages still appear.

Tip:Make sure that your example project is referencing the ActionBarSherlock and SlidingMenu library contained in your workspace.
