问题描述
我有一个android.support.v7.widget.RecyclerView的子类。当我使用应用程序和测试时，它工作的很好。
I have a subclass of android.support.v7.widget.RecyclerView. It works fine when I use the application and testing.
然而，当我在我的gradle应用程序文件中包含espresso-contrib时，我尝试运行相同的试验。该应用程序仍然有效。在armv模拟器和设备上的sdk版本21和22中都会出现同样的问题。
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'
