When to use Enum / Int Constants

Question

I have a question that when should we use Enum and when should we use a final constants?

I know that it has been discussed at Enums and Constants. Which to use when? tho

Answer 1

Basically the Android core is C/C++ code. This works with integers. So when using enums in Java every value had to be "translated". This would cost CPU time and memory. Both are rare on embedded systems.
