Add this permission as well in the android manifest file. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

This is mostly a stab in the dark at the moment. I'm not seeing anything that is popping out immediately. Could you remove the file from your libs directory, remove the line compile fileTree('src/main/libs') from your build.gradle file and add in its place compile 'com.squareup.okhttp:okhttp:2.3.0'

Could you also post the full error output to help track this done more?

Could you also add 

compile 'com.squareup.okio:okio:1.3.0'

to your build.gradle file in addition to the changes I previously mentioned?

I read on stackoverflow we have to use the 1.0.0 okio lib version, but that doesn't do the trick either. Calling Ben Jakuben for this. I get the FATAL Exception error same as OP but even after adding okio both versions in gradle still doesn't do the trick.

EDIT: scratch that. I was using internet permission instead of PERMISSION. Oh java how sometimes you just want me to punch the screen for a stupid mistake.
