GLView crashing in bare project

Environment

Expo CLI 2.11.9 environment info: System: OS: Windows 10 Binaries: Yarn: 1.5.1 - C:\Program Files (x86)\Yarn\bin\yarn.CMD npm: 6.9.0 - C:\Program Files\nodejs\npm.CMD IDEs: Android Studio: Version 3.1.0.0 AI-173.4907809

Target

A real Android Pie device

Steps to Reproduce

1. expo init --template bare-minimum
2. yarn add expo-gl, yarn add expo-gl-cpp
3. Adding GLPackage to MainApplication.java
4. Adding GLView from expo-gl to the app component
5. yarn android

Expected Behavior

App should not crash and show at least a black box.

Actual Behavior

App crashes and closes immediately after opening. Just got a very short glimpse at the black box. This happens always - even if I don’t pass the onContextCreate param or trying to paint a black box on the canvas.

The debug log from Android Studio says:

E/SoLoader: couldn’t find DSO to load: libexpo-gl.so caused by: dlopen failed: “/data/data/com.chllng/lib-main/libexpo-gl.so” is 32-bit instead of 64-bit E/AndroidRuntime: FATAL EXCEPTION: mqt_js Process: com.chllng, PID: 16188 java.lang.UnsatisfiedLinkError: couldn’t find DSO to load: libexpo-gl.so caused by: dlopen failed: “/data/data/com.chllng/lib-main/libexpo-gl.so” is 32-bit instead of 64-bit

If I add ndk.abiFilters "armeabi-v7a", "x86", this error goes, but I got:

A/libc: Fatal signal 7 (SIGBUS), code 1 (BUS_ADRALN), fault addr 0x2e in tid 25832 (mqt_js), pid 25760 (com.chllng)

Any ideas how to solve this?

Hello there, I spent some time removing all the company-specific code and created a demo. Repo can be seen here: https://github.com/reimertz/expo-three-demo

You are a life saver!!! I’m not really sure what was much different from my project to yours other than I started with an Expo Bare project, but yours was clearly a conversion from a basic React Native project. I took that path and now everything seems to be working, which leads me to believe the issue is with the Expo package itself.

Thank you so much for providing that repo, @reimertz !
