you can now reduce the app size by up to 10x by using EAS Build for managed apps in SDK 41+! https://blog.expo.io/eas-build-april-preview-update-ebd7dff9dd25

Google Sign-in fails if "enableDangerousExperimentalLeanBuilds" : true is set in app.json
I have tried on Android 9, 10 and 11.
After clicking on button, the account selection popup/screen doesn't shows up.

Any news on the ios version?
Brent Vatne
Steve Moretz: EAS Build is the way forward here: https://blog.expo.io/expo-application-services-eas-build-and-submit-fc1d1476aa2e
we'll release a beta of managed support in the coming weeks
Steve Moretz
Brent Vatne: When I heard about that EAS build it already blew my head.Didn't know that can support the size reduction as well!
That is just staggering!
Will it be free?
For building once in a week maybe for example?
That is a game changer.
I have a hackintosh it is on my lenovo laptop, apple introduced the new cpus they built and they're going to that gradually.
Meaning every one like me or with old macs using intel cpus will get totally screwed if they can't afford to buy a new mac!
EAS can save our lives!
THANKS MAN

Michael Wood: So none of EAS build/EAS Submit/EAS Update will have a free tier?That is disappointing!
At least developers should be able to make the apps for free with EAS build and then for EAS Submit and EAS Update it is logical to pay.
Michael Wood
Steve Moretz: I think you misread! It says at the bottom "these services will be available under the free plan"
Steve Moretz
Michael Wood: My apologies, I just saw the ticks of the features under free plan, under comparison table.Thanks for clarification.
Ibrahim Arif
Michael Wood: no sir whole thing is a paid service.
Michael Wood
Ibrahim Arif: Please understand that "After graduating from preview" and "will be" means "in the future". They are still working out some issues. When they have done so it will be available as part of the free plan.
Ibrahim Arif
Michael Wood: oh ok.. I didn't read that. Thanks man.

We've designed EAS to be optional and independent from Expo. Making apps with Expo doesn't require EAS. It's for developers who want a cloud service for builds, updates, submissions, team coordination, and other parts of their development workflow.
One reason we've designed Expo to be independent from EAS is that we believe that making Expo free and open source is one of the best ways to make Expo succeed. You can use your own computer to build your apps and your own server to host your updates (it's kind of like the web in this way). Or you can build and set up a workflow on servers from the cloud provider of your choice like AWS or EAS. EAS is designed and run by the Expo team for making Expo apps.
We understand that customers need time to develop the first version of their app and want to try out EAS to see how it works for them. To help small customers become big ones, we want to offer a level of free usage that's useful for starting out before they're ready for production.

I just wanted to give "enableDangerousExperimentalLeanBuilds" : true a shot to see how much it cuts from the size, but my apk build failed.
[stderr] /app/turtle/workingdir/android/sdk40/android-shell-app/app/src/main/java/host/exp/exponent/generated/AppConstants.java:8: error: package expo.modules.splashscreen does not exist
I just thought to report it. Btw, what's the preferred way of reporting issues like this so that it get the attention of the dev team? Would a link to the log file in my account would work? Thanks!
Esther Amara
Behnam Kamrani: Hello, did you fix this issue? I'm also experiencing this
Behnam Kamrani
Esther Amara: sorry; I did not!
Nathanael Martins
Esther Amara: "enableDangerousExperimentalLeanBuilds" : true fails in sdk40 but works in 39. I tried all I could but to no avail. I had to downgrade to sdk39
Esther Amara
Nathanael Martins: I think I fixed it, kinda. I had to download expo-splashscreen package, and it worked.
Nathanael Martins
Esther Amara: Wow! okay. Definitely trying it right now
Edit: It worked. You're a life saver Esther. My app size went from 53 to 31.4 MB
From your name, you're Nigerian. Do you mind if we connect? I'm in search of a smart React Native developer from Nigeria. Here is my Telegram handle https://t.me/nate_martins

Sascha Reuter
Hey folks - Any update on this one? Is https://docs.expo.io/build/introduction/ the planned solution for this?
Michael Wood
Sascha Reuter: Yes, EAS Build is the planned solution:
"The goal for managed projects with EAS Build is to remove the limitations commonly encountered with the expo build service: it will produce smaller binaries by only including the dependencies you need[...]"

Hi, Expo projects are really large for a normal android app. It's hard to download and keep in your phone. I wish there was feature in which we could remove all unused libraries like those in react. Also exclude some unnecessary libraries to reduce size.

https://medium.com/@aswinmohanme/how-i-reduced-the-size-of-my-react-native-app-by-86-27be72bba640 Can this be achieved directly from expo I really feels the app size is very high for expo
Nathanael Martins
When I set "enableDangerousExperimentalLeanBuilds" : true in app.json and try to submit to play store, I get this error/warning:
"This App Bundle contains native code, and you've not uploaded debug symbols. We recommend you upload a symbol file to make your crashes and ANRs easier to analyze and debug."
How do I fix this? Thanks.
Summer Syed
Nathanael Martins: I am getting this warning in play console on my managed flow app too generated on sdk-38.
Nathanael Martins
Summer Syed I just ignored the warning for now while anticipating the Expo team to come up with a better way to reduce app size. At least the Play Store does not prevent the app from being served.
Nathanael Martins
This doesn't work anymore if you're using sdk40. Expo team, kindly fix this Michael Wood
Edit: For future readers, to get it to work, you have to install expo-splash-screen before building.
