Question

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？

以下日志：

Answer 1

如果在运行uiautomator测试时遇到ClassNotFindException：

我们中的一些人得到此错误，因为他们的ROM将文件夹/ data / dalvik-cache置于只读模式。我发现Cyanogen是一个S3。

在那种情况下，在bash中输入：

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

重新运行您的测试，这应该有效。由于dalvik-cache被锁定为应用程序，uiautomator不能要求dalvik解压缩你的测试jar，而dalvik将找不到它的类。

Answer 2

查看删除@UiThreadTest注释或删除runOnUiThread（）调用或重新分解测试工作。但是没有logcat，很难理解它的来源。

Answer 3

有同样的问题。我见过的大多数演示表明将jar安装到/ data / local / tmp /。我已经看到其他人指示尝试将其安装到您的SD卡（/ storage / sdcard0）。这样做之后就有效了。似乎是读取权限的问题。

Answer 4

我通过使用“ant build”来创建我的jar来解决这个错误。如果你在eclipse中使用export来创建一个jar文件，结果类文件中可能会出现一些错误，因此找不到上面的类错误。 / p>
