this. However I have a very similar approach on another activity with
text and it works great. I probably will want to look into your
suggestion later on. But for now im simply looking to see what i'm
doing wrong with my current code. At least for now, so i can get some
peace of mind. Looking at it I see nothing wrong. Neither does
eclipse.
Lets just forget about the button, say i literally did just want a
different image to come up whenever the page was visited. Anyone see
the error? This has been bugging me for days.
