In this article, I will cover how we connected to our Android project, shared (between iOS and Android) library written in C++. If you don't know anything about Android NDK (native development kit) or C++, you can still learn from this article the overall method. That could help your team write logic once and share it. So let’s begin from the library file structure. In the image below we can see that we have three subfolders in our library.

One of the major advantages of Python over other programming languages is its concise, readable code. Even within the Python language itself, though, there are ways to write code that is more elegant and achieves the same end result more efficiently.
