运行仪器命令时出现Android本地驱动程序api错误

我正在使用android本机驱动程序api测试android本机应用程序。运行仪器命令时出现Android本地驱动程序api错误

我遵循指南中提到的链接AndroidMakeAnAppTestable。

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

的错误是：

约ClassNotFoundException的异常会谈为您要加载的类。运行期间

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

ServerInstrumentation类文件未找到time.Please参考以下链接： Android nativedriver, starting an app with istrumentation

我试图重建jar文件，但它仍然显示错误。 – andinrajesh 2012-04-17 08:56:36

当你的android应用程序正在运行时需要类路径上的jar文件 – UVM 2012-04-17 08:57:57

我添加了它。但仍然显示相同的错误。 – andinrajesh 2012-04-19 10:06:17

你通过Eclipse启动？右键单击你的android项目节点，去建立路径，去定购并导出，并确保server-standalone.jar被添加并被“检查”。
