realm-js: UnsatisfiedLinkError when trying to load RealmReactModule

For those who wonder, I had the same issue (RN 0.58.6, Realm 2.25.0) and solved it with

defaultConfig{
        ndk {
            // Tells Gradle to build outputs for the following ABIs and package
            // them into your APK.
            abiFilters 'x86', 'armeabi-v7a'//, 'x86_64', 'armeabi'
        }
}

And also:

• def versionCodes = ["armeabi-v7a": 1, "x86": 2/*, "arm64-v8a": 3*/]
• include "armeabi-v7a", "x86"//, "arm64-v8a" // uncommented coz realm does not support 64 bit yet

Edit: use this only if you’re not planning on releasing a 64 bits version of your app

Still got the error on latest version React Native (0.59.1), Realm 2.25.0. A crash app on some Android devices.

I solve the issue with, using the latest realm 2.22.0 enableProguardInReleaseBuilds = false

@kneth crashes on 2.12.0 and 2.13.0.

java.lang.UnsatisfiedLinkError: couldn't find DSO to load: librealmreact.so

Edit: as @abury said, downgrading to 2.2.8 resolved the issue.

@martnst Yes, the explanation is dlopen failed: "/data/data/com.rntestapp/lib-main/librealmreact.so" is 32-bit instead of 64-bit lib and the fix is using abiFilters. For 64 bit support, see #2221.

@brayanL The solution above requires that all your libraries come in 32 bit versions. And that you only use the 32 bit versions (even if a 64 bit version exists).

The same crash occurred to my app after rebuilding it from scratch with React Native 0.58. Comparing the android/app/build.gradle with my old repo, I noticed that the abiFilters was not present anymore. Thanks @tomas-paronai for you comment.

I was able to reproduce it.

Steps to reproduce this:

• $ react-native init RNTestApp
• $ cd RNTestApp
• $ yarn add realm
• $ react-native link
• run via Android Studio

@AlexandreRozier Many places 🤔. Thanks for the update.
