handling links in a webview

Question

I have my WebView loading all links inside the webview - but when I select an email link it tries to load it in the webview instead of launching an email app on

    //webViewTerms.getSettings().setBuiltInZoomControls(true);
    webViewTerms.loadUrl(getUrl()); //.loadUrl("https://www.google.com/");

            return true;
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            // TODO Auto-generated method stub
            super.onPageFinished(view, url);


        }

    }

Going off of the answer provided by @schwiz, here is a cleaner example. Assuming the WebView is named webView:

webView.setWebViewClient(new WebViewClient() {
    // shouldOverrideUrlLoading makes this `WebView` the default handler for URLs inside the app, so that links are not kicked out to other apps.
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // Use an external email program if the link begins with "mailto:".
        if (url.startsWith("mailto:")) {
            // We use `ACTION_SENDTO` instead of `ACTION_SEND` so that only email programs are launched.
            Intent emailIntent = new Intent(Intent.ACTION_SENDTO);

             // Parse the url and set it as the data for the `Intent`.
            emailIntent.setData(Uri.parse(url));

            // `FLAG_ACTIVITY_NEW_TASK` opens the email program in a new task instead as part of this application.
            emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

            // Make it so.
            startActivity(emailIntent);
            return true;
        } else {  
            // Returning false causes WebView to load the URL while preventing it from adding URL redirects to the WebView history.
            return false;
        }
    }
});

I have tested this with all the mailto: options: multiple email addresses, CC, BCC, subject, and body.

I assume you are already overriding shouldOverrideUrlLoading, you just need to handle this special case.

mWebClient = new WebViewClient(){

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if(url.startsWith("mailto:")){
                MailTo mt = MailTo.parse(url);
                Intent i = newEmailIntent(MyActivity.this, mt.getTo(), mt.getSubject(), mt.getBody(), mt.getCc());
                startActivity(i);
                view.reload();
                return true;
            }

                else{
                    view.loadUrl(url);
                }
                return true;
            }
       };
    mWebView.setWebViewClient(mWebClient);

    public static Intent newEmailIntent(Context context, String address, String subject, String body, String cc) {
      Intent intent = new Intent(Intent.ACTION_SEND);
      intent.putExtra(Intent.EXTRA_EMAIL, new String[] { address });
      intent.putExtra(Intent.EXTRA_TEXT, body);
      intent.putExtra(Intent.EXTRA_SUBJECT, subject);
      intent.putExtra(Intent.EXTRA_CC, cc);
      intent.setType("message/rfc822");
      return intent;
}
