Android studio building signed APK error on "Type of anim"

I trying to build singed apk with Android Studio.

when i press button to create signed apk i get this error :

Error: Expected resource of type anim [ResourceType]

And this line of my java code show's up

LayoutAnimationController lac = new LayoutAnimationController(AnimationUtils.loadAnimation(Employment.this,
R.animator.grow_from_bottom), 0.8f);

I do'nt have any problem to create Unsigned apk. just in singed apk.

Please help me.

thank you.
