Android NDK example

Machine code, also known as native code, is a program which is written in machine language . Machine code is usually considered the lowest level of code for a computer, that, in its lowest level form, is written in binary (0s and 1s), but is often written in hexadecimal or octal to make it a little easier to handle.
