I recommend you to start with B4X programming language guide: https://www.b4x.com/android/documentation.html

You don't need to know visual basic in order to develop with B4X (and there is no reason to learn it).

What is your 'senior's program' ?

As an unlicensed member you don't have access to additional libraries.
My advice for you is to make some apps which don't need libraries. For example: hello world, guess the number, a countdown timer, etc.
