Build issues

[Becca]

Hi,

I'm following the "Getting Started" instructions to get zxing set up
on my android phone, and I keep getting a build error about
inconsistencies and recompiling. I originally ran into a build error
about classes.dex and found a post with a new dx.bat file that's
supposed to fix the issue. Now whenever I run the ant command though,
I get the error below (with or without the dx.bat fix). I've tried
removing the zxing directory and re-compiling, but same error. Is
there something else I need to re-do?

Thanks,

Becca

Try "ant clean" first. It's trying to recompile against heavily-
modified bytecode output by Proguard and that doesn't work. I have the
same issue. I bet there is a better way to do this but I just "clean"
first if I've already built the code before.

That did the trick. Thank you!
