在使用 Android uiAutomator 时，我在尝试在 4.1.2 设备上运行测试时遇到了问题。使用此处输入链接描述中的代码时，尝试滚动应用程序托盘时会引发异常。

我最初认为它是由 api 17 而不是 16 编译引起的，但这似乎不是真的。其他人遇到过这个吗？

引发异常：

UIAutomator 的代码有变化：

4.1.1 method : public void setAsHorizontalList ()
4.2 method : public UIScrollable setAsHorizontalList ()

可能您正在使用 API-17 的 UIAutomator 构建测试，但在 API-16 设备上运行。尝试使用相应的 UIAutomator.jar

From my experiments this week with UI Automator it's still seems immature, with the best support available with android-17 as your target and with a device running 4.2.1. I tried using my Galaxy S device which has 4.1.2 installed and had similar errors to those you report.

FYI: I think there's a bug in Android 4.2.2 that stops scrollIntoView(...) calls from swiping more than once. I've reported the problem to Google https://groups.google.com/forum/?fromgroups=#!topic/adt-dev/TjeewtpNWf8

I found the demo app http://developer.android.com/tools/testing/testing_ui.html worked on my device with Android 4.2.1 You might need to tweak the code slightly, however the method calls do work.

您好，即使我遇到了同样的问题，首先我删除了我拥有的 build.xml 并创建了新的 build.xml 文件，然后运行 ​​ant build。它适用于我尝试相同的..
