Process special URLs in web-view component

If the webpage displayed in the web-view component contains special URLs, such as those starting with a custom scheme like tcmpp://host/path, the host app can intercept and customize the redirections of the URLs.
To intercept URL navigation, create a class that implements the IWebViewLinkProxy API and add the ProxyService annotation:
@ProxyService(proxy = IWebViewLinkProxy.class)
public class CustomWebViewLinkProxy implements IWebViewLinkProxy {

    /**
     * Handle custom url loading in web-view component.
     * Custom url is url with any custom scheme (scheme not network protocol such as http/https)
     * @param miniContext context of mini-program
     * @param url the url which is loading
     * @return return true if the url loading is handled, otherwise false the web-view will handle url loading
     */
    @Override
    public boolean webViewCustomUrlLoading(IMiniAppContext miniContext, String url) {
        Uri uri = Uri.parse(url);
        if ("tcmpp".equals(uri.getScheme())) {
            Intent intent = new Intent(Intent.ACTION_VIEW, uri);
            miniContext.getAttachedActivity().startActivity(intent);
            return true;
        }
        return false;
    }
}
In the implementation, the mini program context and the loaded URL are provided. If the developer handles the URL redirections and returns true, the web-view component will no longer process the URL. If false is returned, the web-view component will process the URL according to normal logic.
