我正在遇到类似的问题,FragmentActivity无法通过ActivityInstrumentationTestCase2进行测试

顶级解决方案存在的问题仅适用于使用Eclipse构建系统.我正在使用Gradle作为我的项目.

在运行ART运行时的Nexus 5上,我的Espresso仪器测试运行完美.当我在Dalvik运行时或模拟器上使用Nexus 4时,我遇到了在测试框架之外运行应用程序时不会发生的异常.

java.lang.NoClassDefFoundError: com.packagename.fragment.ProgressDialogFragment

在日志中,我发现这些可疑消息类似于链接的问题:

ProgressDialogFragment是其子DialogFragment2类,是Android支持库DialogFragment类的子类 …
