    <p>I am trying to have my Android application sent Telnet commands over a small network to another device, and whenever I declare the DatagramSocket it throws a SocketException saying: <strong>Address Family not Supported by Protocol</strong>. Here is my code below:</p> <pre><code> try { addr = InetAddress.getByName(ipAddress); sock = new DatagramSocket(); //SocketException created here //first message - cmd length = cmd.length(); message = cmd.getBytes(); packet = new DatagramPacket(message, length, addr, portAddr); sock.send(packet); //second message - highCMD length = highCMD.length(); message = highCMD.getBytes(); packet = new DatagramPacket(message, length, addr, portAddr); sock.send(packet); sock.close(); } catch (SocketException e) { AlertDialog alertDialog; alertDialog = new AlertDialog.Builder(v.getContext()).create(); alertDialog.setTitle("Send High CMD Error!"); alertDialog.setMessage("SocketException"); alertDialog.show(); } catch (IOException e){ AlertDialog alertDialog; alertDialog = new AlertDialog.Builder(v.getContext()).create(); alertDialog.setTitle("Send High CMD Error!"); alertDialog.setMessage("IOException"); alertDialog.show(); } } </code></pre> <p>Possible solutions I've considered but haven't made work:</p> <ol> <li>Emulator needs port redirect through development machine, which ports to use?</li> <li>I'm not using correct version of IP4/6, how is this set?</li> <li>Device uses TCP protocol, maybe I'm using the wrong socket type?</li> </ol> <p>Other Important Info:</p> <ol> <li>I've only run this on an Emulator</li> <li>Development Machine correctly sent telnet commands from Command Prompt</li> <li>Network consists of development machine, router, and device.</li> </ol> <p><strong>UPDATE: 2/9/11</strong></p> <p>I've changed this code to the following, but I'm still getting an exception:</p> <pre><code> try { addr = InetAddress.getByName(ipAddress); socketAddress = new InetSocketAddress(addr, portAddr); sock = new Socket(); sock.connect(socketAddress); sock.close(); } catch (SocketException e) { AlertDialog alertDialog; alertDialog = new AlertDialog.Builder(v.getContext()).create(); alertDialog.setTitle("Send High CMD Error!"); alertDialog.setMessage("SocketException" + e.getMessage()); alertDialog.show(); } </code></pre> <p>The message from the exception says "Permission Denied." Does this mean that my device is blocking the socket from connecting?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
