我正在尝试在一个multidex项目中使用Spoon进行expresso测试。在使用Lollipop或Marshmallow的设备/ VM中测试运行没有问题，但它们在Lollipop设备下无法正常工作。
在stackoverflow中还有一些关于这个问题的问题，并且所有解决方案都讨论了在Gradle的依赖项配置中避免重复库的问题，但我找不到它们，也没有任何其他问题。
这是make ./gradlew -q：project：dependencies
的结果_debugAndroidTestApk - ## Internal use, do not manually configure ##

答案 0 :(得分：0)
最后，我发现了问题＆gt;＆lt;。
AndroidJUnitRunner与Multidex兼容，因此无需创建替代Runner，因为您可以阅读以下消息：https://plus.google.com/+OleksandrKucherenko/posts/i7qZdVEy3Ue
另一方面，我有一个带有新跑步者和一些测试的模块，但这并不是必需的。我删除了模块并再次将testInstrumentationRunner配置为 testInstrumentationRunner＆＃39; android.support.test.runner.AndroidJUnitRunner＆＃39;问题是固定的。！
