I have studied this link appcompat-v7 v21.0.0 causing crash on Samsung devices with Android v4.2.2 very similarl to my problem. but can't make it.

Steps to fix this: Add the following lines to the proguard file:

-keep class * extends android.support.v7.internal.view.menu.MenuBuilder
-keep class * implements android.support.v7.internal.view.menu.MenuBuilder
-keep class android.support.v7.internal.view.menu.MenuBuilder

Then, refresh the build in your IDE, and build the APK again.

"Why is this happening?" Well, NoClassDefFoundErrors happen when a class went missing at runtime, but was compiled.

I hope I helped you!
