I got this message, during the export signed application package.
[2013-11-11 12:54:26 - Game] Proguard returned with error code 1. See console
[2013-11-11 12:54:26 - Game] Warning: com.threed.jpct.BufferUtilNative: can't find referenced class com.badlogic.gdx.utils.BufferUtils
Shouldn't be a problem. That happens because no libgdx can Bd bound in the path. There's an option to add it and use it for faster buffer uploads on old devices.
I solved it by these lines
-dontwarn com.badlogic.gdx.**
-dontnote com.badlogic.gdx.**
It's just a warning. Does this cause any problem except for a cosmetic one?
Yes, warnings seem to be treated as fatal errors in Proguard, at least when executed from Eclipse.
They just do what Thomas. suggested in the post above. I can do nothing about this except to remove support for Libgdx...which maybe i should do because it's rather pointless on current devices anyway.
Ok, i decided to remove it for the next release. Nobody is using it anyway as far as i know.
