android - uiAutomator 在 4.1.2 设备上失败

Question

在玩 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 enter link description here 中的代码时尝试滚动应用程序托盘时抛出异常。

我最初认为这是由针对 api 17 而不是 16 编译引起的，但事实似乎并非如此。还有其他人遇到过这个吗？

引发异常:

Answer 1

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 来构建测试但在 API-16 设备上运行。尝试使用相应的 UIAutomator.jar
