You have a bad proguard.jar file, you need to replace this .jar by a correct version. The steps below describing how to do that. Some colleagues had the same problem here.

• Go to Preferences => SDK locations and copy the Android SDK location.
• Go to that folder (mostly /Users/USERNAME/Library/Developer/Xamarin/android-sdk-macosx) and go to the folder tools/proguard/lib.
• Here you find a proguard.jar.
• Rename this to proguard_OLD.jar.
• Download the last proguard file (like this one https://sourceforge.net/projects/proguard/files/)
• Unzip and place the proguard.jar in the tools/proguard/lib folder
• Rebuild your Project

Everything should be fixed!
