刚开始使用 appium，参考了论坛的帖子进行安装使用（参考贴：http://testerhome.com/topics/645）。
基础环境已搭建：

操作系统：windows7
appium 版本：0.18.1

运行是报以下错误：
error: Failed to start an Appium session, err was: Error: Activity used to start app doesn't exist! Make sure it exists
info: Error: Activity used to start app doesn't exist! Make sure it exists
at null. (C:\Users\jianglf\AppData\Roaming\npm\node_modules\appium\lib\devices\android\adb.js:1105:19)

请各位帮忙看看，是否需要更改 adb.js 的代码？
