Implementando las características de USSD. Enlace de un servicio a PhoneUtils sin reiniciar el teléfono en cada actualización
Estoy tratando de implementar una aplicación para enviar, recibir y analizar códigos USSD en Android. Hasta ahora he usado el código enhttp://commandus.com/blog/?p=58 con el fin de obtener esta funcionalidad. Para que el servicio funcione, es necesario reiniciar el teléfono. Esto no sería un problema la primera vez que el usuario instala la aplicación, pero lo que he notado al probar el emulador es que el teléfono requerirá un reinicio en cada actualización, incluso si no hay nada nuevo en el servicio. Lo que me gustaría saber es lo siguiente:
¿Podría haber alguna distancia para que PhoneUtils se una a mi servicio sin reiniciar? ¿Al menos en tiempo de actualización?En caso de que no haya manera de hacerlo, estoy pensando en crear 2 aplicaciones, una que es la aplicación normal con la que el usuario interactuaría y otra separada que contiene mi servicio. En este caso, se le pedirá al usuario que ejecute la primera ejecución, en caso de que él / ella requiera alguna de las funciones de ussd, para instalar la segunda aplicación. Me preocupa que esto sea molesto para el usuario. ¿Cuál crees que sería la mejor manera de abordar este enfoque?Para referencia, he incluido el código que utilicé para el servicio, ya que la parte de la interfaz es diferente a la publicada en el sitio web original.
