How the fuck you define a prototype in Android development?

Is it something like "here is the design showing all possible working and functionality, make a working app with all cloud calls integration in 7 days.

If its working as expected, we will just do some ui enhancements, replace your testing firebase with our own broken cloud, replace default pickers with some library or our own broken pickers and spend 30 days on all this plus the testing"

Is this what you define as a prototype? Like yeah the new intern will do the heavy lifting in all his prototype and then we will start the work on our end, in the meantime giving the intern another new prototype idea and scolding him for delay?
