Java和Android上的套接字编程

Question

s = new Socket(InetAddress.getByName(server_address), server_port);
out = new PrintWriter(s.getOutputStream(), true);
in = new BufferedReader(new InputStreamReader(s.getInputStream()));

...

out.println("DESCRIBE " + url + " RTSP/1.0");
out.println("CSeq: 1");
out.println("");

String answer = null;
try {
    answer = in.readLine();
...

If it happen in java project all good and we get answer like "RTSP/1.0 200 OK\\n", but if I run same code on android I haven't any response. Why?

Answer 1

Also println() isn't good enough. You have to send exactly \\r\\n as line terminators for most Internet protocols, not whatever your local system's line terminator is.

Answer 2

My guess without you giving any kind of error messages is that you need to add the Internet permission to your app.
