I want to develop an app which broadcast messages which can be viewed only through this app. so, it can be used by teachers to broadcast instructions which students with this app (or a reciever app) can access. Can anyone help me with ideas to implement this?

You need to have external server which will store the messages. Your client app will then connect to the server and pull new data.

Personally, I'd go with PHP website for the server, as it can be implemented quickly.

Try to have a look on the http://www.parse.com API to implement User access and Push easily. It's really awesome !

You can create a free account and use it until 1 000 000 request by month, which can be enough I think...
