Android Facebook SDK - java.lang.NoClassDefDefFoundError

Question

I am using official android facebook SDK (downloaded from here: http://github.com/facebook/facebook-android-sdk).

When the program reaches the line Facebook facebook = new Facebook(); i get "java.lang.NoClassDefFoundError: com.facebook.android.Facebook".

I created a facebook project from sources downloaded and in my project I added the facebook project in buildpath (in Eclipse right click on my project -> Properties -> Java build path -> Projects -> add projects -> I choosed the facebook project). The project builds ok, I have no errors.

Any suggestions? Thank you all.

try doing this.. open facebook project export that as jar file and add that jar file to your project and then run your project — MKJParekh

Ensure that facebook project is also built before you start your program. Otherwise adding Facebook Project as dependency should have worked fine.
