同样的代码之前能正常进行，但是在对 app 卸载然后安装新版本后就一直报现在的错误：
WebDriverException: Message: UiAutomator died while responding to command, please check appium logs!
可以启动 app，但是也只能启动 app，一旦执行点击操作，就报错
已经做得尝试：
1.重启机器包括安卓机、电脑，问题仍然存在
2.安装之前能用的版本问题仍然一样
3.安卓版本 5.1.1 不存在 API 过低的问 http://www.cnblogs.com/nzyjlr/p/4494256.html
4.卸载安装 app，依然报错
5 修改代码，精简到 http://www.cnblogs.com/fnng/p/4579152.html 这个中的代码 仍然报错
附上 appium log 已经 pycharm 上的报错信息
appiumlog（package 名已经修改）
