*project.properties: *

# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
proguard.config=proguard.cfg

# Project target.
target=android-17
android.library.reference.1=..\\librarySlideMenu
android.library.reference.2=../google-play-services_lib

Расскажите, пожалуйста, о том, как решить эту проблему, и как выполнить настройку proguard.

Заранее спасибо.
