I have a subclass of android.support.v7.widget.RecyclerView. It works fine when I use the application and testing.
However, when I include espresso-contrib in my gradle app file I get an exception when I try to run the same tests. The app still works. The same problem occurs in both sdk versions 21 and 22, on armv emulator and device. Using an x86 emulator it segfaults instead.
Gradle
androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.0'
Exception
