codelab / Comment "threader" une connexion TCP ?

salut, je viens de faire face a ce même problême, mon app android frizait quand le serveru était indisponible.
Je sais que ce post date de quelque mois, mais ça fera toujours une référence supplémentaire :

/*
 * ofTcpClientThread.h
 *
 *  Created on: 7 sept. 2013

#ifndef OFTCPCLIENTTHREAD_H_
#define OFTCPCLIENTTHREAD_H_

#include "ofMain.h"
#include "ofxNetwork.h"
// my thread for the tcp client, sure it can be better, but I'm a padawan
class ofTcpClientThread: public ofThread {

	void threadedFunction() {
		// while(isThreadRunning()) does the thread loop, without that, it work once...
		while (isThreadRunning()) {
// check if my client is connected
			if (myClientTcp.isConnected()) {
// lock the ressource
				lock();
				// let know the main thread we are online
				isConnected = true;
// check if the main thread already read the received data, without that
				// without that the main thread is unable to get the data, strange...
				if (isChecked) {
					rawReceived = myClientTcp.receive();

					isChecked = false;
				}
				// unock the ressource
				unlock();
			} else {
// if client is unconnected

				myClientTcp.setup(ip, 11211);
				// how the message are ended, you must define it.
				myClientTcp.setMessageDelimiter("}");
				// lock the ressource
				lock();
				// let know is unconnected
				isConnected = false;
				// unlock the ressource
				unlock();
			}

		}
	}
	ofxTCPClient myClientTcp;
	// i must define this variables as public, without that i got an error 
	// if i try to access them since the main thread, i got an error about private access
public:
	string rawReceived = "";
public:
	bool isConnected = false;
public:
	bool isChecked = true;
	string ip = "192.168.0.42";
};

#endif /* OFTCPCLIENTTHREAD_H_ */

Donc dans mon code, j'accède depuis le main thread au donné tel que rawReceived, et isConnected, et le main thread lui renvoie le ischecked.
Pour ça je crèe mon trhead par exemple :
Dans le setup :

ofTcpClientThread monThread;
monThread.startThread(true, false);

et dans la partie update je bloque les ressources de mon trhead , puis j'accède a celle ci;

monThread.lock();
isConnected=monThread.isConnected;
datareceived=monThread.rawReceived;
monThread.isChecked=isChecked;
monThread.unlock();

Les fonctions lock et unlock permettent dans le thread et dans le main trhead de bloquer l'accès au ressources, et ainsi les modifier ;)
