UiAutomator exited unexpectedly with code 0, signal null

问题：

使用多进程，Android driver还是会被shut down。

环境：

Appium: v1.16.0
Android Device：4.4.2 （没办法，公司真机环境只能使用这个版本）
Android driver： 4.25.2

基于老师的代码，已经尝试做的修改：

  1. 把Server启动的主函数也改成了进程，而不是线程。
  2. 因公司的app启动后，需要等待机械部分的初始化，所以app启动后需要等待较久时间，BaseDriver的封装，capability增加了"newCommandTimeout" : 2000, 后来改到5000也一样。
  3. 因我们使用2个apk，一个管UI，一个主程序，尝试capability里把"appActivity" 改为"app"，“otherApps”。
  4. 麻烦老师帮忙看下

        write_file = WriteUserCommand()
        devices = write_file.get_value('user_info_'+str(i),'deviceName')

这个问题可以忽略了，已经解决了。

之前调试改了好多地方，忘记改回去导致的。

对比用多进程方式启动，和直接在unittest里创建driver的方法进行，发现问题似乎在于session还是被kill掉了。

以下是多进程的：

//img1.sycdn.imooc.com/szimg/5e6751fa09de195f18240714.jpg

这个是直接在unittest里创建driver的：

//img1.sycdn.imooc.com/szimg/5e6752260913a3bf18230306.jpg

所以还是进程的写法有问题吗？

看了网上其他的解决办法，无法解决。
