WebView - JavascriptInterface

Question

i'm using component navigation. In the application, I have WebView which, if a successful transaction, returns success in javascript, and if unsuccessful it returns unsuccess. Now I use @JavacscriptInterface here. My question is whether and how I can use Navigation.findNavController, for example if it is a success to open a fragment, if it is unsuccessful to open another fragment. I have a problem with how to get View In class where is @JavascriptInterface

Answer 1

You Need to create @JavascriptInterface method and for success and unsuccess. also you need to add this interface in webview :

Add interface:

mWebView.addJavascriptInterface(new YourInterfaceClass(), "webinterface");

public class YourInterfaceClass{
    public YourInterfaceClass() {

    }

    @JavascriptInterface 
    public void success () {
    //do here
    }

    @JavascriptInterface 
    public void unsuccess() {
    //do here

    }
}

and call in your webpage like this : webinterface.success() or webinterface.unsuccess()
