Correct. But this is not where the crash is.

Precisely - only there does it receive location - otherwise it remains null
(the default for an object) and you don't check for null in your draw()
call. Thus, unless you set a valid Location object in your main activity,
your internal location will remain null and you will crash and burn as you
have already seen when your position overlay goes to draw.
