Named Spawn eggs when dispensed are dispensed unnamed

First of all, all I know about my tablet is its a tablet from andriod. Next I don't know whether this belongs in dispencers or spawn eggs. Anyway, I was creating a minigame, and for decoration, I wanted to add named mobs. Because you can't spawn named mobs with commands I tried naming mobs and putting it in dispencers. But when I activate the dispencers, it just says "Skeleton"
