Bug: [V4 Beta] Build failed on Android with Expo

[leoboyerbx]

Bug description

When trying to build an Expo app for android with latest beta (beta.8), even with a correct expo plugin (see #880), we get a build error. It seems that some step is trying to build for armeabi-v7a even if we removed the wrong arch from gradle.properties.

The error:

> Task :react-native-mmkv:configureCMakeDebug[armeabi-v7a] FAILED
C/C++: [PROJECT]/node_modules/react-native-mmkv/android/CMakeLists.txt debug|armeabi-v7a : com.google.prefab.api.NoMatchingLibraryException: No compatible library found for //mmkv/mmkv. Rejected the following libraries:

[Incubating] Problems report is available at: [PROJECT]/android/build/reports/problems/problems-report.html

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':react-native-mmkv:configureCMakeDebug[armeabi-v7a]'.
> [CXX1210] [PROJECT]/node_modules/react-native-mmkv/android/CMakeLists.txt debug|armeabi-v7a : No compatible library found [//mmkv/mmkv]

How to reproduce ?

I've made a repro repo from a fresh Expo 54 Beta template: repo

Steps to reproduce

1. Clone the repro repo and checkout the correct branch

git clone https://github.com/leoboyerbx/rn-repros && cd rn-repros && git checkout issue/android-arch-error

2. install dependencies

bun i

3. Prebuild

bunx expo prebuild -p android

4. You can verify that the android/gradle.properties includes the correct reactNativeArchitectures=arm64-v8a,x86_64 (around line 30)
5. Try to run on a real device

bun run android --device

The error should show up.

Note: setting up a local environment that can build Android locally is needed to use the repro

It seems that some step is trying to build for armeabi-v7a even if we removed the wrong arch from gradle.properties.

Did #880 fix the issue for that? Then we can close this issue once I do a release.

[leoboyerbx]

Unfortunately no...
#880 was there to fix the expo plugin crashing and not outputing the correct gradle.properties. This issue is reproductible even with #880 merged, that's where my skills in Android building fall short.

This issue happens even with this requirement satisfied.

[mrousavy]

For me it doesn't. CI also builds.
You can try cleaning cache and doing a sync + rebuild, but that should normally work

+1 on this. I tried it two weeks ago when expo 54 was still in beta. And i tried it now after release again.
I'm still getting the same issue.

[JeremyPercy]

#880 fixed it for me!

[mrousavy]

Thanks for testing @JeremyPercy! Released it under 4.0.0-beta.9! :)

[mrousavy]

Can anyone look into creating a CI test for this so this plugin won't break again in the future? I don't use react-native-mmkv in Expo so I can't test this myself.

[leoboyerbx]

@mrousavy sure, I am away from a computer for one more week, but plan to do it when I come back.

[madflanderz]

I tried 4.0.0-beta.9 and still had local build issues when i figured out, that my Expo.dev build was running fine. So the problem seems to be only on my local computer.

But after these steps it was finally working:

• cd android && ./gradlew --stop
• rm -rf ~/.gradle/caches
• rm -rf ./node_modules
• npx expo prebuild --platform android --clean
• npm install
• npx expo prebuild --clean
• npx expo run:android

It's still not building for me, even with beta 9, same error as OP
