Android Add PinIt Button using Pinterest Jar NoClassDefFoundError

Question

I am trying to add the Pinit button to my Android App. I have downloaded the SDK and copied the pinit-sdk-1.0.Jar into my Project/libs folder. I'm even able to make the necessary PinItButton import to my code. But for whatever reason, my XML isn't finding the Button widget, and so I tried to add it just using Java with this code:

LinearLayout ll = (LinearLayout)findViewById(R.id.pinterest_layout);
        PinItButton pinit = new PinItButton(this);
        ll.addView(pinit);

I know this is the correct way to add something using code because I tested it by adding a generic Button first. I run my project then, and it crashes on the line where I set up the PinItButton. This is the error that my logcat spat back at me:

07-22 01:19:52.160: E/AndroidRuntime(32367): java.lang.NoClassDefFoundError: com.pinterest.pinit.PinItButton

I believe that I'm understand what it is telling me, but what else should I be attempting then to create the PinIt button? Any help would be great. Thank you!

It was @Kai who helped me figure out my problem. I needed to check my libraries. I did that by going to project --> Properties --> Java Build Path --> Order and Export tab, then checking the library and clicking OK. My problem was then solved!
