[android-developers] Re: glGenTextures going crazy on actual device

Lance, (and everyone)

Thank you so much! That was exactly it. All I had to do was rename
my drawables folder to drawables-nodpi (and I did a full rebuild just
to be nice) and now everything is back to normal, with api 4 in place.

Of course, now I have to decide if I want to support higher rez
screens at the expense of frame rate or not. It's so PRETTY, but it's
at least 50% slower. :)

Again, I was really pulling my hair out on this. Of course it might
have been NICE if the GL Error Check actually mentioned it didn't feel
the texture was a power of two. I, of course, just knew that it was,
so I never logged a getWidth() on it. It's still a little odd that
some textures were happier than others, but I imagine that is
something to do with which wrong-sized-texture stepped on the memory
of which other. :-)

Once again, thank you!

- Dan
