[Crash] can't find libhermes.so in certain cases (64bit?)

[MayrPatrick]

Context:

we're having a hybrid app (native + RN), that is using React Native 0.60.4 and Hermes for the RN part.

Current behavior/problem:

the release build (universal APK) that incorporates the Hermes "adaptions" (= switch) is working fine for a big chunk of our userbase but crashes for the others.

crashMessage:
mostly: couldn't find DSO to load: libhermes.so,
whereas other users have a slightly different message:

couldn't find DSO to load: libhermes.so caused by: couldn't find DSO to load: libc++_shared.so caused by: dlopen failed:"/data/data/.../lib-3/libc++_shared.so" is 32-bit instead of 64-bit

(could also be lib-1, lib-2, ...).

Additional info:

• crashLocation: SourceFile line 738 in com.facebook.soloader.SoLoader.ॱ
• crashException: java.lang.UnsatisfiedLinkError

What we did:

a.) switching the "enableHermes" flag from false to true

b.) add a couple of pickFirst entries to the build.gradle file

packagingOptions {
        pickFirst 'lib/x86/libc++_shared.so'
        pickFirst 'lib/arm64-v8a/libc++_shared.so'
        pickFirst 'lib/x86_64/libc++_shared.so'
        pickFirst 'lib/armeabi-v7a/libc++_shared.so'
    }

(similar to what facebook/react-native#25601 (comment) suggested/did)

c.) we had to order the dependencies within the dependencies.gradle file as follows (excerpt)

dependencies {
	api 'com.facebook.react:react-native:0.59.10'
	// Workaround for using Hermes as JS engine
	api fileTree(dir: 'libs', include: '*.aar')
	api 'com.facebook.react:react-native:0.60.4'

Maybe your project has different so files between 32 bit and 64 bit.

they seem to be correct :-/

I pulled the (installed) apk from a phone via adb pull ... and after unpacking it, compared the libs with the ones from the hermes-release.aar package. They are identical and therefore I'm thinking that those are fine.

I'm facing a similar situation. I'm using react native 0.62.0 and in my app/build.gradle I had to set those pickFirst to solve some linking problems:

packagingOptions {
        pickFirst 'lib/x86_64/libjsc.so'
        pickFirst 'lib/x86/libjsc.so'
        pickFirst 'lib/arm64-v8a/libjsc.so'
        pickFirst 'lib/armeabi-v7a/libjsc.so'
        pickFirst "lib/armeabi-v7a/libc++_shared.so"
        pickFirst "lib/arm64-v8a/libc++_shared.so"
        pickFirst "lib/x86/libc++_shared.so"
        pickFirst "lib/x86_64/libc++_shared.so"
    }

I correctly published my app on the store and now I'm getting crash on some devices with android 5 and android 6.

Interestingly enough, all the devices I got the error with were running an Intel Atom chipset (not sure if relevant).

The error:

java.lang.UnsatisfiedLinkErrorSoLoader.java:789
couldn't find DSO to load: libhermes.so caused by: APK was built for a different platform

Any updates herE?
