Problem with android Proguard.

[kiffa]

For some reason, i need obscure my code by using Proguard.

And when i do this, there was an error:

[2012-09-17 11:26:12 - AndroidDog] Proguard returned with error code 1. See console

Seems jPCT-AE.jar referenced the class  com.badlogic.gdx.utils.BufferUtils, does this class be useful? If so, how to import it?

[EgonOlsen]

That class is part of libgdx. jPCT-AE can make use of it if libgdx is in the classpath. Just download libgdx and adds it to the classpath when running proguard. You don't have to use in your actual project though. It can be useful on older Android version but on current ones, it's not really needed to bother with it unless you are animating large objects in which case it might help with performance.
