SOS les amis,je veux créer un petit exemple de chat avec les sockets sur android:l'idée c'est que le serveur(classe java) quand il reçoit un message il doit le diffuser à toute les clients(android) connectés mon exemple ne marche pas comme prévu prière de me donner un coup de pouce
voici le code serveur:
et voici le client
Code : Sélectionner tout - Visualiser dans une fenêtre à part
