Why is my filesize so big?
I'm working on an android app for my school, and they want the filesize to be pretty small. I'm somehow getting 22.5 MB total for the build. I have 4 image files, each less than 230 KB before being brought into Unity, and all the other files under assets are either scripts or a custom binary file, which is only 19 KB. I've opened the editor log, but it's not making any sense. The percentages don't add up to 100%:
Build Report
Uncompressed usage by category:
Textures 10.7 mb 29.0%
Meshes 0.0 kb 0.0%
Animations 0.0 kb 0.0%
Sounds 0.0 kb 0.0%
Shaders 13.1 kb 0.0%
Other Assets 4.6 kb 0.0%
Levels 81.2 kb 0.2%
Scripts 624.7 kb 1.7%
Included DLLs 3.9 mb 10.7%
File headers 9.1 kb 0.0%
Complete size 36.7 mb 100.0%
What's all this unaccounted for space? How do I compress this more? If anyone needs more info, like the whole build log, or something else, I would be happy to oblige (To an extent). I'm just not sure how much is important.
I'm usually don't worry much about filesize, so this is all pretty new to me. Thanks in advance for any help!
