Solution

You have different support library added into your projet:

Found 2 versions of android-support-v4.jar in the dependency list, but not all the versions are identical (check is based on SHA-1 only at this time).

That means that you must have the same version of that jar in your project and all the libraries you are using.

To solve it you can remove the android-support-v4.jar that is in your projet. And after you can chose one of that jar somewhere in your computer (you can chose the one provided by the sdk) and after you paste it everywhere you have to include it. This solved the issue for me.
