这是很容易做的快捷方式，

It's quite easy to make the shortcut,

final Intent i = new Intent(); //intent for the shortcut
final Intent shortcutIntent = new Intent( /*put necessary parameters (i.e activity to launch)*/ );
shortcutIntent.putExtra(Browser.EXTRA_APPLICATION_ID /*if your launching a browser*/,
        Long.toString(/*put unique id e.g. system time etc.*/));
i.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
i.putExtra(Intent.EXTRA_SHORTCUT_NAME, /*title*/);
i.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,/*drawable*/);
i.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
sendBroadcast(i);

有关URL拦截，在WebViewClient

for url interception, in a WebViewClient

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
    if (url.equalsIgnoreCase(/*your sitemap url*/)) {
        //use the above code
    }
    return true;
}

我希望这有助于。我没有测试过这一点，但，这是一般的想法！祝你好运

I hope this helps. I have not tested this but this is the general idea! Good luck
