Espresso with support.v4 ViewCompat throws NoSuchMethodError on load

Question

I'm using Espresso to automate my app testing. My app has 1 ActionBarActivity and 1 fragment using android.support.v4.app.Fragment. The app works fine but when I attempt to run a Espresso test, I get an error when launching app.

java.lang.NoSuchMethodError: No static method isLaidOut(Landroid/view/View;)Z in class Landroid/support/v4/view/ViewCompat; or its super classes (declaration of 'android.support.v4.view.ViewCompat' appears in /data/app/com.example.android.app.test-1/base.apk)

    Test running failed: Instrumentation run failed due to 'java.lang.NoSuchMethodError'

I'm using Android Studio. Thanks in advance!

Exclude support-v4 from the espresso-contrib library.

   androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2') {           
         exclude module: 'support-v4'
   }
