Application Android à l'aide de Socket pour envoyer et recevoir des messages:

J'ai une application android que j'essaie d'utiliser pour envoyer et recevoir des messages vers un serveur à l'aide de la connexion socket.

J'ai eu toutes sortes de problèmes d'envoi et de réception. J'ai été en mesure de faire l'un ou l'autre, à aucun moment les deux.

Je me demandais si quelqu'un pouvait m'aider avec un exercice simple que je peux le compiler à l'aide de BufferedReader et PrintWriter de le faire.

J'apprécie toute l'aide que je suis sur le point d'abandonner.

Merci d'avance.... Ci-dessous, quelques clichés de ce que j'ai essayé (même Si elles ne sont pas pertinentes à cette question, j'espère que cela montre que j'ai essayé avant de demander ici).

    private OnClickListener sendClickListener = new OnClickListener(){
public void onClick(View arg0) {
Thread cThread = new Thread(new ClientThread());  
cThread.start();  
}};    
public class ClientThread implements Runnable {  
public void run() {  
try {  
EditText dstAddress = (EditText) findViewById(R.id.destinationAddress);
EditText dstMessage = (EditText) findViewById(R.id.messageToTranslate);
EditText dstPort = (EditText) findViewById(R.id.destinationPort);
String address = dstAddress.getText().toString();   
String message = dstMessage.getText().toString();
int port = Integer.parseInt(dstPort.getText().toString());
InetAddress serverAddr = InetAddress.getByName(address);  
Log.d(".Coursework", "C: Connecting...");  
Socket socket = new Socket(serverAddr, port);  
connected = true;  
while (connected) {  
try {  
EditText dstTranslation = (EditText) findViewById(R.id.returnedTranslation);
dstTranslation.setText("help me");
Log.d(".Coursework", "C: Sending command.");  
PrintWriter out;
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);  
out.println(language);
out.println(message);
Log.d("ClientActivity", "C: Sent.");  
//BufferedReader in;
//in = new BufferedReader(new InputStreamReader(socket.getInputStream())); 
//String translation = in.readLine();
} catch (Exception e) {  
Log.e("ClientActivity", "S: Error", e);  
}  
}  
socket.close();  
Log.d("ClientActivity", "C: Closed.");  
} catch (Exception e) {  
Log.e("ClientActivity", "C: Error", e);  
connected = false;  
}  
}

pw.write(message+"\n");

pw.close();
//Send off the data
//NOTE: Either I am not receiving the message correctly or I am not sending it from the server properly.
String translatedMessage = br.readLine();   
System.out.print(translatedMessage);
br.close();
//Log.d("application_name",translatedMessage); Trying to check the contents begin returned from the server.
return "Say What??";
