Something funny that I don't know why

yes, just very funny about this problem well, I just make five sprites with same animation. They work fine in the Unity Editor Environment, yes, no problem. But when I build my project and output the apk file then install on my real android phone for a test, there's a problem! One of the sprites animation can't play! Yes, four works fine but one can't do the animation! They all just work fine on UnityEditor!
