Android : Android : How to give permission to certain users to start Activity on Parse user type property?

assume that i have two types of users: students and instructors.

ObjectID    UserName   Password    Type
-------     --------   --------   ------
8uJ03j7     user#1      ***        student
2835ruJ     user#2      ***        instructor
2835JhL     user#3      ***        student

Every time a user enter username and password and click log in i want to check their Type. For example if user is student to Start new intent and open activity for student , same thing for Instructor.

I know how to make intent just need to check their type .
