Why android webView sometimes need TypeScript or javascript mount WebViewJavascriptBridge to window by self ?

Because when you use window.WebViewJavascriptBridge in android webView,but window.WebViewJavascriptBridge did not finish loaded!!!

On the other hand iOS WKWebView have webView?.configuration.userContentController.addUserScript(...) And WKUserScriptInjectionTimeAtDocumentStart this mean:

WKWebView can inject the script after the document element has been created, but before any other content has been loaded.
