Much of that is because the android tools are absolutely horrid, they tried to make things simple but ended up making them insanely complicated. Compare a hello world tutorial for android (http://www.tutorialspoint.com/android/android_hello_world_ex...) with one for the desktop (https://developer.gnome.org/gtk-tutorial/stable/c39.html#SEC...) to get an idea of just how crazy android is.
