App crashing with proguard enabled in react-native 0.57.X - couldn't find DSO to load: librealmreact.so

Goals

Trying to build a production ready apk (Android).

Actual Results

App crashes if proguard is enabled (def enableProguardInReleaseBuilds = true).

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

It crashes no matter if you split in several apks or only one.

This is my proguard config:

# Disabling obfuscation is useful if you collect stack traces from production crashes
# (unless you are using a system that supports de-obfuscate the stack traces).
-dontobfuscate

Hi, I add “-keep class io.realm.react.**” into the file proguard-rules.pro. Now it runs well

react-native : “0.59.3” Adding : ndk { abiFilters "armeabi-v7a", "x86" } To build.gradle defaultConfig fixed it for me.
