我正在使用 android native driver api 来测试 android native 应用程序。

我遵循提到链接AndroidMakeAnAppTestable的指南。

但是当我尝试运行检测命令时，它不会在命令行中显示任何错误，但会在 eclipse 中显示。

错误是：

该异常涉及您尝试加载的类的 ClassNotFoundException。

ComponentInfo{com.google.android.testing.nativedriver.simplelayouts/com.google.android.testing.nativedriver.server.ServerInstrumentation}: java.lang.ClassNotFoundException: com.google.android.testing.nativedriver.server.ServerInstrumentation in loader

运行时未找到 ServerInstrumentation 类文件。请参考此链接： Android nativedriver,starting an app with istrumentation

你是通过 Eclipse 启动的吗？右键单击您的 android 项目节点，转到构建路径，转到订购和导出并确保添加了 server-standalone.jar 并“选中”。
