Kotlin android development tutorial - Creating a Dialog Interface
In this Kotlin android development tutorial we will be creating an interface for the DialogFragment.
Which will send the webpage title to the calling activity using an interface.
Once the main activity has the title it will find the matching title in the WebBackForwardList using a Kotlin range. Upon completion of finding the match the WebView’s goBackOrForward function will be called with the correct offset. Which will result in the history page being loaded.
