In my android app teacher will add students to a course which I will stored in a SqlLite database...Now, when students install that app he will be notified if he was added to that course or not...and he can give attendance for that course...now I want to know how students will be notified for that add course though the database is only saved on teachers devices storage? how to implement that...plz help

I've tried SqlLite database and I'm expecting that it can be also used for student.. but the problem is that the data are being stored in the local storage of teachers device..
