abstract method not being picked up

I'm getting the following error: The type new MyWebViewClient(){} must implement the inherited abstract method MyWebViewClient.launchExternalBrowser()

    DCWebView.setWebViewClient(new MyWebViewClient() {
        public void launchExternalBrowser(String url) {
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            startActivity(intent);
        }
    });

I don't understand because according to my code I am defining the method. 

public abstract class MyWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (Uri.parse(url).getHost().equals("www.url.com")) {
            // This is my web site, so do not override; let my WebView load the page
            return false;
        }
        // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
        launchExternalBrowser();
        return true;
    }

    public abstract void launchExternalBrowser();
}

Change the method launchExternalBrowser() as like this inside MyWebViewClient like this:

public void launchExternalBrowser(){

}

you are implementing public void launchExternalBrowser(String url) instead of implementing public void launchExternalBrowser() the difference is in the parameter list of the method

You override the method with one argument, while the compiler seems to complain about a method with no argument. Maybe you'll need to override both (or just the one without any arguments - depending on the abstract class).

You forgot to include the string parameter in the abstract declaration of launchExternalBrowser.

public void launchExternalBrowser(String url)

is not the same as

public abstract void launchExternalBrowser();

To satisfy the class implementation, you have to implement a function with the exact same signature as the abstract method. If you want to passing in a string as an argument, you must define the method that was in the abstract class.
