How does Android use WebView to access https websites?

In Android, WebView can be used to access http and https websites. However, when the https website is accessed by default, if the certificate is not recognized by Android, a blank page is displayed without any prompts, in this case, we must add more configurations.

This method is only applicable to Android 2.1 and later versions.
