当我运行我的 android UIAutomator 代码时，它显示以下错误。

INSTRUMENTATION_RESULT：shortMsg=java.lang.RuntimeException
INSTRUMENTATION_RESULT：longMsg=com.android.ui.testing
INSTRUMENTATION_CODE：0

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？

如果在运行 uiautomator 测试时遇到 ClassNotFindException ：

我们中的一些人收到此错误是因为他们的 ROM 将文件夹 /data/dalvik-cache 置于只读模式。使用 Cyanogen 的 S3 发生在我身上。

在这种情况下，输入 bash ：

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

重新运行您的测试，这应该可以工作。由于 dalvik-cache 对应用程序已锁定，因此 uiautomator 无法要求 dalvik 解压缩测试的 jar，并且 dalvik 不会找到它的类。

查看是否删除 @UiThreadTest 注释或删除 runOnUiThread() 调用或重构您的测试工作。但是没有 logcat，很难理解它的来源。

有同样的问题。我见过的大多数演示都表明将 jar 安装到 /data/local/tmp/。我看到其他人表示尝试将其安装到您的 SD 卡 (/storage/sdcard0)。这样做之后，它起作用了。似乎是读取权限的问题。

我通过使用“ant build”来创建我的 jar 解决了这个错误。如果你在 eclipse 中使用 export 创建一个 jar 文件，生成的类文件中可能有一些错误，因此上述类未找到错误。
