除非您使用user2558882的想法，否则除非有其他工具可以为您提供网站图标，否则您将必须同时检查http和https网址。没有其他方法可以做到这一点。这是使用网络的困难之一。
也许以不同的方式看待您的代码并将您尝试做的事情分解为更小，更易于管理的部分会更好一些？
public void getFavicon(String host) { URL httpUrl = this.getHttpUrl(host + "/favicon.ico"); Bitmap favicon = this.getBitmap(httpUrl); if (favicon == null) { URL httpsUrl = this.getHttpsUrl(host + "/favicon.ico"); favicon = this.getBitmap(httpsUrl); } if (favicon == null) { throw new FaviconMissingException("Unable to find favicon for host: " + host); } return favicon;}public URL getHttpUrl(String uri) throws MalformedURLException { // There are better ways of building a url then string concationation. return new URL("http://" + uri);}public URL getHttpsUrl(String uri) throws MalformedURLException { // There are better ways of building a url then string concationation. return new URL("https://" + uri);}public Bitmap getBitmap(URL url) { InputStream inputStream = getInputStream(url); Bitmap bitmap = BitmapFactory.depreStream(inputStream); return bitmap}public InputStream getInputStream(URL url) { // Please use a real connection library like HTTPClient here! // HttpClient will handle timeouts, redirects, and things like that for you. HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setDoInput(true); connection.connect(); return connection.getInputStream();}顺便说一句，关注一个或两个连接需要花费更多时间，然后编写代码以发出两个请求。我几乎保证Google会根据需要发出两个请求。如果它对Google足够好，对我来说也足够好。
最后，如果您开始发现发出两个请求确实花费了太多时间，则可以采取一些措施来提高性能。
