Android UiAutomator 快速调试

背景：在Eclipse中不能直接运行Uiautomator工程，所以每次编写一份用例都要进行手动输入命令，很烦。调试起来不仅繁琐还浪费时间。网上找到一份快速调试的代码UiAutomatorHelper，可将这几步进行简化很方便(当然也可以使用bat文件，相比之下还是这个方便)。

create buildxml file：android create uitest-project -n <jar_name> -t <androidId> -p <path>

ant build xmlfile：ant build

push jarFile：adb  push <jar_path>  data/local/tmp

Run Test：adb shell uiautomator runtest <jar_name> --nohup -c <testClass.testName>

步骤：将UiAutomatorHelper.java放到工程目录下（与测试脚本同目录），在测试脚本中写个main方法。然后Run as ->java application即可
