Appium+python自动化测试过程中问题

 一、自动删除contactmanager

自动化测试appium提供的sample如下包/activity:com.example.android.contactmanager/.ContactManager ，发现提示如下错误

info: [debug] Error: Activity used to start app doesn‘t exist or cannot be launched! Make sure it exists and is a launchable activity
>     at [object Object].<anonymous> (C:\Program Files (x86)\Appium\node_modules\appium\node_modules\appium-adb\lib\adb.js:1146:21)
>     at [object Object].<anonymous> (C:\Program Files (x86)\Appium\node_modules\appium\node_modules\appium-adb\lib\adb.js:180:9)

> info: [debug] Responding to client with error: {"status":33,"value":{"message":"A new session could not be created. (Original error: Activity used to start app doesn‘t exist or cannot be launched! Make sure it exists and is a launchable activity)","origValue":"Activity used to start app doesn‘t exist or cannot be launched! Make sure it exists and is a launchable activity"},"sessionId":null}
> info: <-- POST /wd/hub/session 500 2518.066 ms - 346

发现提示该包不存在。很奇怪我安装了之后确认能够运行了之后再运行的自动化代码，为什么提示不存在呢？

于是观察模拟器运行界面信息，发现启动代码后自动把模拟器中的contactmanager删除了，那当然找不到这个包和activity啦。

二、Failed to start an Appium session, err was: Error: Requested a new session but one was in progress

这是由于之前的会话没有关闭，然后你又开启了测试实例，解决方法： 
1. 停止appium服务 
2. 在Genarel Setting那里设置覆盖Session，重启Appium

测试结束在AfterClass加driver.quit()
