It\'s the first time I am using Proguard, I\'ve noticed that if you add many custom rules to proguard-project.txt it takes obviously much more time for building
proguard-project.txt
Fixed, I read all the others forum posts about the problem but no one said how to fix it on Eclipse. I found the fix here
EDIT: in case the link becomes dead, here's what you can do. Edit "eclipse.ini", and set something like that:
-XX:MaxPermSize=1024m -Xms512m -Xmx1024m
