J'ai créé une application de connexion qui fait partie de mon processus de création d'applications natives.Il y a peu de points de terminaison utilisant la session de connexion. Il ne transmettait pas sa session à l'activité suivante. Par exemple: Si l'utilisateur est connecté, il peut accéder au reste des fonctionnalités dans d'autres activités. Mais pendant que j'essaie de changer d'activité, j'obtiens «l'utilisateur a besoin de se connecter».Comment créer une connexion http qui gère automatiquement si le client change d'activité

Donc, selon vous, je dois analyser correctement la connexion aux classes intéressées. Mais le reste du point de terminaison ne prendra pas ces informations d'identification en tant que paramètres. Comment pourrais-je être en mesure d'envoyer ce message réussi à la classe intéressée. Pourriez-vous s'il vous plaît expliquer avec un exemple de code. @Gabe Sechan – Arun
Regardez dans BroadcastReceivers. Ou un bus d'événement. Ou un RxJava observable. Ou juste un service lié avec un rouleau votre propre système de rappel. Il existe des dizaines de façons d'alerter les activités d'un Service, de faire des recherches. –
Ohh d'accord .. Merci @Gabe Sechan – Arun
