Hey guys, I wanna ask something about APK build size from unity
so I have 2 projects and the one with more textures size have smaller apk size rather than the one with less textures, and the difference is big. Am I doing something wrong here? these 2 projects are completely different but both are 2D game. Both are build only for Arm CPU. Not development build, nothing in resources and streaming folder.
below is the log screenshoot
I’d guess that the textures you used in your 2nd project are much more compressible in a ZIP file. APK files are just JAR files which themselves are just ZIP files. The uncompressed file size of something doesn’t have much to do with how well that file can be compressed. For example if you included a text file in your build with a trillion of the same character, that would show as quite large in that Build Report, but would compress to almost nothing when it gets into the APK.
For more information, research how file compression works, specifically how it applies to ZIP files.
I see, is there anyway to know the size after compress for each image? I’m trying to find what’s causing the big file size, and I always thought the editor log is the way to go
Hi! Youre “Build Report” not include sizes of included files?
Usually im look Editor.log file after Build and find “Used Assets and files from the Resources folder, sorted by uncompressed size”. There will be a list like this:
It can help to find much problem and big textures.
What’s actually happening is that in one project you set your textures to compress, and in the other you didn’t, if you look at the textures properties in unity you can setup this stuff for each texture/platform, you can also lower their resolution and get even more compression.
There’s also the issue where you might have created sprite packs, which might also save space.
