android - 包含 espresso-contrib :2. 0 时的 java.lang.IncompatibleClassChangeError

Question

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正常。

但是，当我在我的 gradle 应用程序文件中包含 espresso-contrib 时，当我尝试运行相同的测试时出现异常。该应用程序仍然有效。同样的问题出现在 sdk 版本 21 和 22，在 armv 模拟器和设备上。使用 x86 模拟器它会出现段错误。

Gradle

androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.0'

异常
