ECS subscene can't work on android?,subscene can't run on android

It works on PC.when i use the subscene.
but when i build it on android.
I can’t see any subscene.
,I open the sample ecs project and build the subscene sample scene in android
but it turns out that
I can’t see the subscene on android device.

I’m guessing it’s because you needed to add the android platforms package. If you update to ecs 0.5+ the platforms are all combined and you simply need to add the platforms package.
