Hi everyone,
I am working on my graduation project which is developing android application.
The application will be LMS learning management system.
It will be for a school and the teachers and students will use it.
My doctor asked me to draw a sequence diagram ,, note that I did not start coding and implementation phase yet. How can I draw this diagram and how can I specify the objects of my app to start drawing?

What I have tried:

I tried to specify the objects ..
User , log in interface , database , android app
I am not sure if this is right or not.

"My doctor asked me"
What's your doctor doing here?

Why aren't you asking your teacher this? Break down your requirements. The nouns in your requirements are *generally* your objects. The verbs in your requirements become your methods.

First you should draw the class diagram. Using the class diagram you can identify objects.

Sequence diagrams shows objects interactions, message flow between objects. As you are developing a LMS possible objects might be Student , Course , Assignment , Subjects etc..
