I understand it's a problem due to conflicts of library, but if I remove one of this I can't use some class or method. I necessarily need both.

Answer 1

Yo don't need both libraries, just add:

compile 'com.android.support:support-v13:19.0.1'

In your build.gradle and you'll be fine because support-v13 contains support-v4

Answer 2

I had the same issue. I ccouldn't build the project because of this project, fortunately I am not using the support library in my project so I commented the support library instance on the build.gradle file, then I compiled the project and everything want fine.

Finally, I uncommented that line again and build the project and the issue was gone. That problem is related with including support library twice. Hope this works for you.
