The idea is, teachers just send any message in the app and hit send. I want it to save into database using PHP. After that, whenever the students are connected with network, I want to make it automatically get the message sent by teachers and notify the students through notification bar.
I think it is possible but I don't know what is the correct term to google the tutorial. Any suggestion? I just want to make it simple. Teachers only send message and students only get message. Nothing much.
