今天做微信H5自动化，切换H5报错。
找到思寒大佬帖子 微信 webview 的自动化技术
对于这里的androidProcess值有一个疑问，看到有跟帖也是有其他的值，不清楚这个值是怎么来的？
查相关的进程是如下 
麻烦老师们指点一二
你发的那个截图下面就有讲这个值是怎么来的
不过我看了一下帖子是16年的了，那时候旧版本的appium有BUG才导致切换context有问题，于是加上了这种方法来临时解决问题，现在的appium应该已经没有那个问题了，建议你还是发具体的报错信息来分析一下
webview的context是：WEBVIEW_com.tencent.mm:tools，目前是取和 context 的最像的
。因为查了进程有许多，对 androidProcess 进程的理解不明确 。
而且，我现在用的appium不加这句还是会报错呢
环境
Python: 3.7
Appium: v 1.17.0
相关代码如下
def start(cls):
caps = {}
caps["platformName"] = "Android"
caps["deviceName"] = "test"
caps["appPackage"] = "com.tencent.mm"
caps["appActivity"] = ".ui.LauncherUI"
caps["noReset"] = True
caps["autoGrantPermissions"] = True
caps["skipServerInstallation"] = True
caps["skipDeviceInitialization"] = True
caps["chromedriverExecutable"] = r'D:\chromedriver.exe'
caps["chromeOptions"] = {
'androidProcess': 'com.tencent.mm:tools'
}
cls.driver = webdriver.Remote("http://localhost:4723/wd/hub", caps)
cls.driver.implicitly_wait(10)
return MainPage(cls.driver)
将chromeOptions注释后报错信息如下：

这个问题解决了吗？我换了N个版本的chromedriver，还是没有解决，看上去像是adb -P 5037 -s e1cedc89 forward --remove tcp:10902导致的
