Android design support library and proguard

Question

I'm using CoordinatorLayout (and other new widgets in android design library) in my project, But when I want to create a signed APK it gives me CoordinatorLayout errors.

Should I do some changes in my proguard?

Answer 1

Just add these two lines to your progaurd-project.txt file:

-keep class android.support.design.widget.** { *; }
-keep interface android.support.design.widget.** { *; }
