[Solved] webview Switch Error: Failed to start Chromedriver session: Failed to get sockets matching: @weblayer_devtools_remote_.*4738

def switch_to_webview_wx(self):
    # context = 'WEBVIEW_com.tencent.mm:tools'
    context = 'WEBVIEW_com.tencent.mm:toolsmp'
    self.__switch_to(context)
    time.sleep(3)
    self.__sel_handle()

When switching webview, throwing exceptions, the context I was using before was: WEBVIEW_com.tencent.mm:tools, then it became WEBVIEW_com.tencent.mm:toolsmp

Only modify the value of context, still the same error is reported, see the log has loaded “androidProcess”: “com.tencent.mm:tools”,

 

Solution:

Modify desired_caps to “androidProcess”: “com.tencent.mm:toolsmp”, and it works!

"appPackage"      :   "com.tencent.mm",
"appActivity"     :   ".ui.LauncherUI",
"app"             :   "",
"noReset"         :   true,
"fullReset"       :   false,
"noSign"          :   true,
"unicodeKeyboard" :   true,
"resetKeyboard"   :   true,
"skipServerInstallation" : true,
"skipDeviceInitialization" : true,
"chromedriverExecutableDir" : "\\res\\chromedriver\\",
"chromedriverChromeMappingFile" : "\\res\\chromedriver\\chromedriver.json",
"chromeOptions"   :   {
      "androidProcess" : "com.tencent.mm:toolsmp"
