android client not working [migrated]
- by Syeda Zunairah
i have a java client and c# server
the server code is
static Socket listeningSocket;
static Socket socket;
static Thread thrReadRequest;
static int iPort = 4444;
static int iConnectionQueue = 100;
static void Main(string[] args)
{
Console.WriteLine(IPAddress.Parse(getLocalIPAddress()).ToString());
try
{
listeningSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
//listeningSocket.Bind(new IPEndPoint(0, iPort));
listeningSocket.Bind(new IPEndPoint(IPAddress.Parse(getLocalIPAddress()), iPort));
listeningSocket.Listen(iConnectionQueue);
thrReadRequest = new Thread(new ThreadStart(getRequest));
thrReadRequest.Start();
}
catch (Exception e)
{
Console.WriteLine("Winsock error: " + e.ToString());
//throw;
}
}
static private void getRequest()
{
int i = 0;
while (true)
{
i++;
Console.WriteLine("Outside Try i = {0}", i.ToString());
try
{
socket = listeningSocket.Accept();
// Receiving
//byte[] rcvLenBytes = new byte[4];
//socket.Receive(rcvLenBytes);
//int rcvLen = System.BitConverter.ToInt32(rcvLenBytes, 0);
//byte[] rcvBytes = new byte[rcvLen];
//socket.Receive(rcvBytes);
//String formattedBuffer = System.Text.Encoding.ASCII.GetString(rcvBytes);
byte[] buffer = new byte[socket.SendBufferSize];
int iBufferLength = socket.Receive(buffer, 0, buffer.Length, 0);
Console.WriteLine("Received {0}", iBufferLength);
Array.Resize(ref buffer, iBufferLength);
string formattedBuffer = Encoding.ASCII.GetString(buffer);
Console.WriteLine("Data received by Client: {0}", formattedBuffer);
if (formattedBuffer == "quit")
{
socket.Close();
listeningSocket.Close();
Environment.Exit(0);
}
Console.WriteLine("Inside Try i = {0}", i.ToString());
Thread.Sleep(500);
}
catch (Exception e)
{
//socket.Close();
Console.WriteLine("Receiving error: " + e.ToString());
Console.ReadKey();
//throw;
}
finally
{
socket.Close();
//listeningsocket.close();
}
}
}
static private string getLocalIPAddress()
{
IPHostEntry host;
string localIP = "";
host = Dns.GetHostEntry(Dns.GetHostName());
foreach (IPAddress ip in host.AddressList)
{
if (ip.AddressFamily == AddressFamily.InterNetwork)
{
localIP = ip.ToString();
break;
}
}
return localIP;
}
}
and the jave android code is
private TCPClient mTcpClient;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText editText = (EditText) findViewById(R.id.edit_message);
Button send = (Button)findViewById(R.id.sendbutton);
// connect to the server
new connectTask().execute("");
send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String message = editText.getText().toString();
//sends the message to the server
if (mTcpClient != null) {
mTcpClient.sendMessage(message);
}
editText.setText("");
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public class connectTask extends AsyncTask<String,String,TCPClient> {
@Override
protected TCPClient doInBackground(String... message) {
mTcpClient = new TCPClient(new TCPClient.OnMessageReceived() {
@Override
public void messageReceived(String message) {
publishProgress(message);
}
});
mTcpClient.run();
return null;
}
@Override
protected void onProgressUpdate(String... values) {
super.onProgressUpdate(values);
}
}
}
when i run the server it gives output of try i=1.
can any one tell me what to do next
