مشکل در obfuscate کردن پروژه (حل نشده)

زمانی که در مرحله آخر finish رو میزنم با ارور زیر مواجه میشم و از لایبرری v4 هم استفاده میکنم فقط

 [2014-12-30 18:35:36 - VideoPlayer] Proguard returned with error code 1. See console

# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
-dontoptimize
-dontpreverify

# If you want to enable optimization, you should include the
# following:
# -optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*
# -optimizationpasses 5
# -allowaccessmodification
#
# Note that you cannot just include these flags in your own
# configuration file; if you are including this file, optimization
# will be turned off. You'll need to either edit this file, or
# duplicate the contents of this file and remove the include of this
# file from your project's proguard.config path property.
