uiAutomator在4.1.2设备上失败

Question

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.

我最初认为它是由编译api 17而不是16而引起的,但这似乎不是真的.还有其他人遇到过吗？

提出例外:

Answer 1

UIAutomator的代码有变化:

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

也许你正在使用API​​-17的UIAutomator来构建测试,但是在API-16设备上运行.尝试使用相应的UIAutomator.jar
