comment faire pour utilise Socket service avec différent activités
salut
bon j' entrain de développe une application client serveur (serveur java/ client android)
donc je maître en place un service qui doit établie connexion avec le serveur
tous marche bien
problème que je utilise les méthodes de service pour envoyer au receive des message de serveur
donc je lance le service a partir de MainActivity mais j'arrive pas a envoyé un message au serveur
merci d'avance
