[Android] Couldn't find DSO to load crash in release build and hermes is enabled

Description

Hermes is enabled with following packaging options in android.

packagingOptions { if (enableHermes) { // For Hermes, delete all the libjsc* files exclude "/libjsc*.so" if (taskName.contains(“Release”)) { // Reduce size by deleting the debugger/inspector exclude '/libhermes-inspector.so’ exclude ‘/libhermes-executor-debug.so’ } else { // Release libs take precedence and must be removed // to allow debugging exclude '/libhermes-executor-release.so’ } } else { // For JSC, delete all the libhermes* files exclude “**/libhermes*.so” } }

Getting this crash on release build.

Hello, for people who just migrated to RN 0.69.+ and are facing this issue too on Android, you should update android/app/build.gradle with the following code as Hermes now comes bundled with React Native accordingly to the official documentation :

dependencies {
    // ...

    if (enableHermes) {
+       implementation("com.facebook.react:hermes-engine:+") {
+           exclude group:'com.facebook.fbjni'
+       }
-       def hermesPath = "../../node_modules/hermes-engine/android/";
-       debugImplementation files(hermesPath + "hermes-debug.aar")
-       releaseImplementation files(hermesPath + "hermes-release.aar")
    } else {
        implementation jscFlavor
    }
}

This resolved the issue for me, hope it can help a few of you.

Best regards.

This worked for me

This is also happening in my Android environment. I’m working on bumping from 0.63.2 to 0.67.1, and the application in the release build crashes immediately before the splash screen.

Multiple logs of couldn't find DSO to load can be seen in the adb log output. An excerpt is below.

#33065, #33079 also looks like a very similar Issue. However, each seems to have a different version of RN. Is there a widespread impact on the release build?

※This problem did not occur in the debug build
