Message et Transfert de Fichiers via Bluetooth sur android

Je développe une application dans laquelle nous devons d'abord trouver et se connecter disposition des appareils Bluetooth appariés. J'ai fait jusqu'à la connexion. Mais après ce que j'ai mis un écran qui vous demande de choisir entre le Texte et le transfert de fichiers. Lorsque je sélectionne du texte, puis un autre écran s'ouvre dans laquelle il y a edittext et bouton. Quels que soient les types d'utilisateurs dans edittext et clique sur le bouton qui devraient être transférés connecté en BT appareil comme BT application de chat. Je suis passé par BT application de chat, mais il est complexe à comprendre. Je veux une autre fonction qui ne le transfert tâche. Ci-dessous mon code de connexion.
