Question Build size increase when updating to IAP 4.2+

Hi,

Due to Google Play Billing Library 4.0 being enforced, I have updated to from IAP 4.1.3 to IAP 4.4.0. I understand that now the Analytics library is being added to my project as a dependency. In my case this comes with a 5MB increase in build size(see file sizes before and after update). The previous version (4.1.3) was just ~1MB in my build, and now I get 5MB of extra stuff that I don't need. On top of that, I have also an Instant version of my game, and the challenge there is to be under 15 MB core size. Before updating my build sizes were ~14MB, and after update I'm above 16MB which will prevent me from rolling out future updates.

Is there a way to get rid of the new Analytics from my build and just stick with the IAP?

Sorry cause it's irrelevant but does IAP 4.4.0 solves the google play billing version 4 error only play console. and also mention your unity version. your response is highly appreciated. Thank you

 

I did not go productive with 4.4.0, I rolled back to 4.1.3, so I do not know about the play console message. In theory it should dissapear.

I'm on 2020.3.33

 

it worked for me but not my admob ads aren't showing up.. i guess it would be an sdk issue

 

Thanks Jeff for clarifying.

 

Hi Jeff,
Is there anything we can edit/remove/tweak ourselves to avoid those few megabytes?

 

hopes intensify...

 

Here it is. I added the "txt" extension so it can be uploaded here.

 

Hi Jeff, Even we are concerned about the increase in 5MB build size due to IAP 4.4.0+ upgrade . Any reduction in size is highly appreciated.

 

We have added IAP 4.4.0+ and it has increased our size by 5.5 mb. I am amazed why such a small package is taking so much size.

Does unity even test before publishing package? Is the size aspect even taken into consideration?

Overall the package size should be reduced, on top of that there should be an option to choose purchasing platform if anyone chooses only 1 platform then it should reduce the size even further.

 

Hi Jeff,

Any help regarding how we can reduce the size with latest IAP 4.4.0+ plugin?

Earlier it used to take less than a mb but now it is taking 5.5+ mb in build size.

 

Thanks for the reponse. Meanwhile is there anything else we can do to reduce size manually ?

 

Jeff, I've been browsing through the discussions on this sub-forum and correct me if I'm wrong, but all these extra dependencies are added so that revenue is reported via the new Analytics?

 

Hi Jeff,

I can see that 4.5.0 has been released, has the issue been addressed in it?'

Also is that any page/forum where we can check to see if there are any updates about this issue ?

 

Thanks for the response

 

Hi Jeff,
Thanks for checking this, I’m not sure how this thread didn’t get more responses.

We spend literally weeks of work trying to shave a few KB from the build, by optimizing code, graphic assets, using special algorithms just so we can remove certain libraries and even not adding new features that will take too much space,

And then all of a sudden we get this mandatory 4-5 MB increase just to force us to use Unity Analytics.

From this thread (Q: Why does the IAP SDK depend on the UGS Analytics SDK?)
https://forum.unity.com/threads/faq-for-iap-4-2-and-adoption-of-ugs-analytics.1327011/
It seems that it was done for “ C# compilation expediency and performance efficiency”,
Honestly, we would do fine without this efficiency, instead, we could add tons of new features to the game that will cost 4-5 MB

I’m not really sure what are our options, we can try and learn how to implement IAP with native code, it’s something we never had to deal with because Unity covered those parts so far...

 

@JeffDUnity3D Any update form the engineering team? Build increase around 5.1 mb. We can add many features and assets in this 5 mb. Which is taken by IAP plugin. Please update about the issue.

 

Hi agorain,
Is there any way to implement IAP without the unity package? (and preferably without resorting to native code)
Google used to have their own implementation, but it doesn't support Google Play Billing 4
https://developer.android.com/google/play/billing/unity
And I guess most asset store assets use Unity IAP behind the scenes.

 

I'm using EasyIAP in my project and that's just a wrapper.

@comixplay if you do find alternatives, please share

 

Updating to IAP package 4.4.1 increased my generated symbols file by around 500mb - even after stripping and rezipping, I'm still at 330mb (an increase of 90mb from previous build) which is above store limit. Any solution?

 

I have made a sample project which has only these SDKs: IAP + Firebase + Admob.
And these are the size stats.



Note: this project is on IL2CPP with both architectures.

Please find the attached project.

In symbols folder, delete all the files with extension : dbg.so
Zip the remaining, this will decrease your symbols size. We do the same when i have this issue.

 

How long we have to wait for this?
Play console requirement is to update all games IAP 4+. And it is increasing build size of all games. This is not fare at all.

 

Okay Thanks

 

Unfortunately this makes android instant games impossible as it makes even an empty project's build go past the 15.7mb limit

 

I removed IAP's altogether from my instant build. Instead of the purchase workflow I just pop up a message "please install the game". It's stupid and it's sad, but it's better than not being able to update the game at all.
