in just a simple "hello world" example

the string "hello world" is contained in an xml file "strings"

this seems overly complex .. why isn't "hello world" in the program code (say main is it?)

I just don't understand why. Is it because strings may be different (unicode) between devices?

also anyone know any fast track tutorials for java/eclipse/android .... many tutorials out
there are far too ponderous for my tastes -- need stuff that gets right to core issues fast
