Why hello world is 2.16MB?

Question

Android

Each of us does hello world in his first application, I also did everything following the instructions, but one thing confused me - why does an application that simply displays this line take as much as 2.16 MB? I've seen a lot of good apps that take up less than 2 MB, so I'm interested in this question.

Answer 1

Because in ancient computers you simply output Hello World to the current black and white, character terminal, and now you allocate memory, create an object, start a process, create a dialog box, display text in it in a certain font, and then clean it all up after yourself , and close the window.
All this is done by the libraries that you have connected to your program.

Answer 2

Most likely, standard libraries are stuffed there in their entirety + information for debugging (it can inflate the size of simple programs ten times). Check your compiler settings, Debug or Release build you are doing.

Answer 3

remove unnecessary libs
