Internal Memory Size of Delphi Android app

I am using Delphi 10.1.2 Berlin. I need to determine the size of the internal memory in a Delphi Android application project, but I have not found an example even though I searched on Google. I need your help in this regard.

USE GOOGLE "size of the internal memory in a Delphi Android application" - the universe is your limit!
