java.net.UnknownHostException

Question

public static final String readURL(String url)throws Throwable
{
  try {
   InputStream in = (InputStream) fetch(url);

   throw e;
   }
}


public static final Object fetch(String address) throws MalformedURLException,IOException {
 URL url = new URL(address);
 Object content = url.getContent();

}

I am behind a proxy and when I try

readURL("http://abc.com")

to access URL http://abc.com it throws java.net.UnknownHostException: I have:

<uses-permission android:name="android.permission.INTERNET" />

in manifest file.

Any quick solutions?

Answer 1

It is possible that fetch does not do the necessary DNS lookups. If you nslookup abc.com you get a redirect to www.go.com. This may be the problem.

Answer 2

Proxy proxy = new Proxy(Proxy.DIRECT,
    new InetSocketAddress(proxyHost, proxyPort));
url.openConnection(proxy);

or

System.setProperty("http.proxyHost", "my.proxyhost.com");
System.setProperty("http.proxyPort", "1234");
