In this chapter, you have seen how to use WebViewClient and WebChromeClient to respond to specific
events that happen in your WebView. However, it is possible to do even more by injecting arbitrary
JavaScript objects into the document contained in the WebView itself. Check out the documentation
at developer.android.com/reference/android/webkit/WebView.html and scroll down to the
addJavascriptInterface(Object, String) function. The documentation uses Java method
signatures, but remember that Object is equivalent to Any in Kotlin. Using this, you can inject an
arbitrary object into the document with a name you specify:
developer.android.com/reference/android/webkit/WebView.html
-> https://developer.android.com/reference/kotlin/android/webkit/WebView
Object -> Any
The documentation uses Java method
signatures, but remember that Object is equivalent to Any in Kotlin. -> must be deleted.
Thanks.
