Program type already present: android.support.v4.app.FragmentTransitionCompat21$1

Hello there,

After opening a new empty android studio project and typing compile 'com.jjoe64:graphview:4.2.1' into the app's build.gradle file, I get this error. It is also appearing on android studio of a colleague of mine:

Program type already present: android.support.v4.app.FragmentTransitionCompat21$1

Any idea what's going on?

Thanks a lot before hand, excited to get started with GraphView! :)

i don't think it's direct an issue of graphview, maybe more like a generic gradle dependencies issue or so. better ask at stackoverflow
