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

Create a folder named libs inside the root directory of your project and put twitter4j jar inside.

Then include new jar via Project Properties -> Java Build Path -> Libraries -> Add Jars.

Remove any old reference to twitter4j jars.

Clean and launch.
