Android Twitter4j giving error NoClassDefFoundError: twitter4j.TwitterFactory

Question

I am making an app that communicates with Twitter to post a tweet. My problem is that when compile my code, I get the error message:

NoClassDefFoundError: tw         


        

Answer 1

I've found the solution now. The problem was that I was using a very old version of Twitter4j, and in my libs folder, there were multiple jars with identical names. I have now fixed those problems and it is now working perfectly.
