FIleheaders are 56.3% (356.8 mb) of my android apk.

  • I do not have any files in a resource or prefab folder.
  • I have tried unchecking Lightmap static on the files where it was checked, like is suggested on this forum in a couple of places
  • I am not using the Unity terrain system

I do have a lot of assets in the scene. I am not sure how to get around this problem, any info would help.
Thank you.

Problem kind of solved. It seems the issue has to do with light baking. I created a new project and re-imported everything as a prefab and the size is down from 200mb to less than 35mb. So I guess I am not supposed to light bake android games?
