当我运行android UIAutomator代码时，它显示以下错误

检测结果：shortMsg=java.lang.RuntimeException
检测结果：longMsg=com.android.ui.testing

我刚刚运行了developer.android.com中给出的示例代码
如何解决这个错误

01-05 01:07:53.559:D/AndroidRuntime（5712）：>>>>>>>AndroidRuntime开始com.android.internal.os.RuntimeInit查看是否删除@UiThreadTest注释或删除runOnUiThread（）调用或重新分解测试工作。但是如果没有logcat，很难理解它是从哪里来的
 我通过使用“ant build”创建我的jar解决了这个错误。如果在eclipse中使用export创建jar文件，那么在生成的类文件中可能会有一些错误，因此上面的类找不到错误。
如果在运行uiautomator测试时收到ClassNotFindException:

我们中的一些人会遇到这个错误，因为他们的ROM将文件夹/data/dalvik缓存置于只读模式。这在我身上发生了一个S3的氰化物

在这种情况下，在bash中键入：

adb shell 
su
chmod 777 /data/dalvik-cache
exit

重新运行您的测试，这应该会起作用。由于dalvik缓存被应用程序锁定，uiautomator无法要求dalvik解压缩测试的jar，dalvik也找不到its类
 也有同样的问题。我看到的大多数演示都表明要将jar安装到/data/local/tmp/。我看到其他人表示要尝试将其安装到sd卡（/storage/sdcard0）。在这样做之后，它起了作用。读取权限似乎有问题。
如何运行？仿真器？版本？您需要查看logcat输出以了解java.lang.RuntimeException是否存在。请提供日志cat输出。你知道这一点吗？我也有同样的问题，我尝试了这一页上的所有答案，但没有成功。我正在尝试使用Eclipse导出来创建jar文件。
