Hi,
Has anyone created a SOCKS network client on Android? Namely, I'm trying
to simply open a network connection to an HTTP server through a Dante SOCKS
server (from Ubuntu Server 12.04.3 LTS), set up to allow connection without
any authentication. SOCKS server is verify to work by using Firefox.
Then, I ran the following snippet on Android and then on Desktop Java:
(PROXY_ADDR and PROXY_PORT are the proxy address and port that Dante runs
on, connected through WiFi)
URL url = new URL("http://www.android.com:80/";);
Proxy proxy = new Proxy(Proxy.Type.SOCKS,
InetSocketAddress.createUnresolved(PROXY_ADDR, PROXY_PORT));
HttpURLConnection urlConn = (HttpURLConnection)
url.openConnection(proxy);
urlConn.connect();
urlConn.getResponseCode();
These 5 lines works and gives me a 200 OK when run on Java 1.6 on my
Desktop, however the same code runs on a Galaxy Nexus (Android 4.3) results
in Dante log showing "socks protocol error" and then Dante disconnects the
client. This is the logcat output:
