title: android - socket timeout while connecting
body: <p>I'm trying to implement a tcp client app on Android. When I try to connect to my C++ server, the socket times out while trying to connect to the server.</p>
  
  <p>My code:</p>
  
  <pre><code>new Thread(new ClientThread()).start();
  try
  {
    PrintWriter out = new PrintWriter(new BufferedWriter(
      new OutputStreamWriter(socket.getOutputStream())), true);
    out.println("Test message.");
  }
  catch (Exception e)
  {
    // ERROR1
    e.printStackTrace();
  }
  
  ...
  
  class ClientThread implements Runnable
  {
    @Override
    public void run()
    {
      try
      {
        InetAddress serverAddr = InetAddress.getByName("192.168.1.116");
        socket = new Socket(serverAddr, 9000);
      }
      catch (Exception e)
      {
        // ERROR2
        e.printStackTrace();
      }
    }
  }
  </code></pre>
  
  <p>First, the ERROR1 occurs (socket is null), then the ERROR2 occurs (connection time out). The server is working fine, I have tested it with different clients. I have "uses-permission" so it shouldn't be a problem.</p>
  
  <p>EDIT:
  stack at ERROR2:</p>
