U puede enviar y recibir mensajes utilizando la clase SMSMAnager. U puede implementar Receptor personalizado que en msg recibido notificará al usuario que ha llegado el mensaje .. Aquí estoy adjuntando el código que he escrito para enviar y recibir mensajes usando el receptor de difusión personalizada, podría serle útil. Nota: Esto es para la versión 1.6 anterior. Por lo tanto, asegúrese de hacerlo en 2.0 o 2.2 preferiblemente.
pasar por ella y tratar de ponerlo en práctica ..
