Android symbols.zip is too big

Hey all,

there was a thread that is somehow related, but it is unfortunately not followed anymore, so I decided to start another one.

I have the option "Create symbols.zip" enabled but the generated zip size is too big > 400MB whereas Google Console accepts only up to 300MB.
StackTrace Log Type is set to ScriptOnly. Looking inside the archive I can see that there are 2 symbols - one for each selected architecture (ARMv7 and ARM64).

What to do in this case? Such archive is not accepted by Google Play Console.

Unity 2019.4.3

P.S.
I'm not alone with this issue, somebody asked the same question on SO also

 

Did you try rezipping the content with maximum compression level?

 

Hey @kaarloew , thanks for suggestion, that helped to reduce the size to ~120MB !
I hope Unity devs will see this and apply better compression for the generated symbols.zip

 

That helped reduce the file size, but now you cannot upload it:

"The native debug symbols contain an invalid directory my_app.symbols. Only Android ABIs are supported."

 

Previously re-zipping worked without an issue, but now its throwing invalid error!

 

@carbon_studios
U need to unzip it, go to the folder, zip the contents, not the folder itself.

 

My team also has this issue in all our projects. Our games are quite small in fact, but the native debugging symbols zip is way above the Google Play upload limit of 300 MB.

The workaround to unzip and rezip works fine. We've also automated this in our custom build pipeline, but please Unity, just fix this in your code. I don't know how it's possible to even create such a large zip in the first place, but for me, it's a one-liner with the NetStandard2.0 ZipFile library and it does a much better job at compressing the file. Zipping also only takes a fraction of a second, so I don't think there's any reason to prefer less compression. The Google Play upload works fine as well.

 

Here to support this request for better compression of the symbols .ZIP file. Just unzipped the contents and rezipped using .7z and went from 360MB to 92MB. The contents themselves are 360MB uncompressed, so it would appear the "zipping" that unity does doesn't involve any compression at all.

 

In my case symbols.zip is almost 2 GB. When rezipping it I get 500 MB which is still too much. Are there any other suggestions?

 

I've got the same problem

 

Check this:

And also what helped me at the end was deleting the debug files and renaming the others to libil2cpp.so then zipping them again. Other way with the dbg. files it always goes over 300mb

 

Same problem. My symbols are about 1.5GB when rezipping I get around 400mb. How can this be solved? Somebody found out?

And why are those symbols so big anyways in the first place?

 

Most likely because you have so many plugins in your project.

 

Same problem on Unity 2019.4.22f1. My debug symbol folder is 1.6GB after re-zipping it reduces to ~450mb. I tried swift -d command to remove symbol table and also DWARF debugging info as per this documentation but no luck.

How can I further reduce it below 300mb?

 

Nope

 

I've got the same problem
nothing works to reduce it repacking to below 300mb

Any solutions?

 

Nice, re-zipping in 7zip "Ultra" compression level brought mine down from about 750 MB to 189 MB. And my game is very simple and small although it does have a big size if I zip up the project directory (for like a backup), partially due to the cache but also I have unneeded assets in there that I should probably delete.

 

Please fix in LTS! Is this bug being tracked?

 

When you're building an App Bundle with multiple architectures, is the symbols.zip file still conformant? I see folders for multiple architectures inside the zip archive. Does Google know how to parse this?

 

Fantastic!

Off topic question, does Google provide an API to upload both app bundles and symbols? Or are there so many manual steps to create a release anyway, that it makes more sense to manually upload to the Google Play portal? Just hoping to avoid building an API upload if it turns out that it's not workable and someone else already knew.

 

Google has API for uploads, but it is not trivial to use it since it requires service account creation
