I am trying to make use of the SlidingMenu Library for Android but I get these errors:

```
Could not find com.slidingmenu.lib.SlidingMenuActivity.apk

```

and another error:

```
E/AndroidRuntime(24767): java.lang.NoClassDefFoundError: com.slidingmenu.lib.SlidingMenu

```

I have properly added the `com.slidingmenu.lib.SlidingMenuActivity` to the Java Build section.
