Android game does not work with prefab and works without it

Hi. I have android 2d game and have a problem with one prefab(i have more). This prefab is a object with animation.I made APK, and when i started the game on my phone, i seen Unity screen and then game close without any error messeges.I tried to change compression format on animation's sprites, and other comression and quality stuff, nothing helped me. Also I look at logcat and didn't finded something important. And the most interesting thing i created empty project copy my to it, and everything works.I don't have any script which doing something with this prefab, just prefabs which stay in scene and load when game started and work after.Please help me.
