谁能告诉我如何解决Android中的

？
请看下面的错误，我一直在尝试使用
HttpURLConnection
对象访问这个URL。

See the code of my method below
public static String getResponseFromHttpUrl(URL url) throws IOException {
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
try {
InputStream in = urlConnection.getInputStream();
Scanner scanner = new Scanner(in);
scanner.useDelimiter("\\A");
boolean hasInput = scanner.hasNext();
if (hasInput) {
return scanner.next();
} else {
return null;
} finally {
urlConnection.disconnect();
