Android Studio build error - Multiple dex files define Landroid/support/v4/

Question

I am unable to build my project in Android Studio. I get the following error:

Error:Android Dex: [RaditazAndroid] Unable to execute DX
Error:Android Dex: [R         


        

Answer 1

I had the same error.

Removing a library(jtwitter.jar) form my-project/app/libs folder helped me.

Then cleaned the project and ran it and it worked.
