Bug APK size increased in 2021.2

I am making a VR game for the Oculus Quest, only based on the XR management, without other plugins.
My game was 27MB previously. I upgraded to 2021.2 and not my apk is 45MB.

Am I the only one and are there things to look at?

 

Yep, there are different and bigger files in 2021. Assets are slightly smaller and lib has a decent difference
Left if 2021:

 

Made a bug report: Case 1377938

 

I have the same problem after upgrading the project to 2021.2.5. Is there any progress on this problem?

 

Not yet, no reply to my bug report either

 

Thank you for your reply, please let me know if there is a result, thank you!

 

I have the exactly same problem. Is there an any progress?

 

The reply I got was simple that the build process changed and that a small increase can be the result. In the build logs you can find where a lot of the storage is going

 

Thank you for the reply. I'm gonna investigate apk more but I have a +20mb on the build.

 

Any update on this? Upgraded from 2019.4 to 2021.3 and our APK went from just over 1GB to 3GB. This is unacceptable.

 

Maybe check build logs?

 

Anything in particular to look out for in the build logs?

 

What takes up space

 

my apk size increased from 82 to 96 MB when I upgraded from 2020.3 to 2021.3

 

Can you give a link?

 

It wasn't made into a case, but here is the reply:
Hi Dylan,

Thanks for reporting the issue.

I have checked the project you provided and the size increased by 10 megabytes when upgrading from 2020.3 to 2021.2, this however, is not the case with a completely new project where the size increased only by a few megabytes. So the increase in size is more related to the project rather than upgrading Unity, however, keep in mind that with every new main Unity version e.g 2021.X and 2022.X new features are added and functionalities are slightly changed/modified.

You can check here on how to reduce the size of your builds: https://docs.unity3d.com/Manual/ReducingFilesize.html

I checked the build files. The 2021.3 update increased the size of the libil2cpp.so file.

 

Yep, that be unity stuff. You can increase il2cpp code striping in player settings and put the builds at faster (smaller) builds im build settings

 

Same happened to me. Is there any progress?

 

same Problem,, anyone have solution ??

 

Uninstall any unused packages and build for small size

 

My previous build (it should be build with 2019) is 52.5 Mb(.aab) file. When i uncompress total folder size is 225.6 Mb.
My new build(2021.3.10f1) is 105.6 Mb(.aab) file. Uncompressed size is 194 Mb.(Compression method Default or LZ4HC not changed this numbers too much).

Uncompressed sizes almost same but compressed .aab files has huge difference. Even i compressed both folders still 2021 build has double size. I don't know the logic on compressing progress but somehow Unity 2021 build files for Android could not be compressed as good as 2019 build files.

 

.aab file : base/assets/bin/Data

Unity 2021 has one file data.unity3d
Unity 2019 has a lot of file for data.

data.unity3d -> might have some kind of compression and second compression on this file might not work well.

 

Tried removing unnecessary packaged and enabled shader striping etc?
If so, maybe make a bug report and attatch this post

 

My build have slightly different but i think it's clear that new Data folder is not good for compressing.

When i compressed Data folder inside aab file:
Unity 2019 : 153 Mb(Uncompressed) -> Compressed : 27 Mb
Unity 2021 : 88Mb(Uncompressed) -> Compressed : 67 Mb

 

I know. My reply stays the same

 

Ok, here is my fault

1 - In 2019 i was using old sprite packer and when i ported my project to 2021 sprite packer wasn't active.
2 - data.unity3d : This file is only creating when i select compression method on build settings other then default.

2019 aab file size was 52.5
2021 aab file size is now 61 Mb which is acceptable (this might be because of my update)

DevDunk thanks for your interest and time.

 

Guys! I had similar issue, AAB file size increased from 135MB to 178MB. BUT Google Play allows to upload bigger AAB files!

Hi!
After upgrading from 2020.3.41 to 2021.3.21 I managed to decrease assets size. And lib folder is less. But the resulting .apk size increased.

 

any updates here? My build size increases almost twise after upgrade! What happens?

 

any update on this bug? I can find the issue on unity's issue tracker
