[0.60.3] App crash on startup when enabling Hermes (enableHermes: true)

[bhaskarGyan]

App is crashing when I enable Hermes in android/app/build.gradle. App is working fine with react-native 0.60.3 with enableHermes: false

Error:

Steps To Reproduce

1. Follow the steps mentioned in hermes
2. react-native run-android --variant release

Describe what you expected to happen:
App should not crash

The same thing is happening to me, the build is successful, but:

1. The metro bundler doesn't start up
2. I have this error

[benoitdion]

you'll need to add

def enableHermes = project.ext.react.get("enableHermes", false);

at the top of your build.gradle file and

  if (enableHermes) {
    def hermesPath = "../../node_modules/hermesvm/android/";
    debugImplementation files(hermesPath + "hermes-debug.aar")
    releaseImplementation files(hermesPath + "hermes-release.aar")
  } else {
    implementation jscFlavor
  }

in your dependencies.

Should we move those bits of configuration to react.gradle?

[mjmasn]

If you have additional build types those will need to be added too, e.g.

    integrationImplementation files(hermesPath + "hermes-release.aar")
    stagingImplementation files(hermesPath + "hermes-release.aar")

Because we have a few build types, and apart from debug they should all be in release mode, I also had to add some react.gradle fixes. We have a custom react.gradle so this wasn't too much trouble. Basically changing targetName.toLowerCase().contains("release") to !targetName.toLowerCase().contains("debug").

if (!targetName.toLowerCase().contains("debug")) {
    // Can't use ?: since that will also substitute valid empty lists
    hermesFlags = config.hermesFlagsRelease
    if (hermesFlags == null) hermesFlags = ["-O", "-output-source-map"]
} else {
    hermesFlags = config.hermesFlagsDebug
    if (hermesFlags == null) hermesFlags = []
}

and

// Delete the VM related libraries that this build doesn't need.
// The application can manage this manually by setting 'enableVmCleanup: false'
//
// This should really be done by packaging all Hermes releated libs into
// two separate HermesDebug and HermesRelease AARs, but until then we'll
// kludge it by deleting the .so files out of the /transforms/ directory.
def isRelease = !targetName.toLowerCase().contains("debug")

Also added a quick fix for #25609

ant.move(
    file: jsBundleFile,
    tofile: "${jsBundleFile}_temp"
);
commandLine(getHermesCommand(), "-emit-binary", "-out", jsBundleFile, "${jsBundleFile}_temp", *hermesFlags)

In my case I saw this crash when:

1. I first build release with enableHermes: false
2. Change enableHermes: true
3. Build release

all while

def enableHermes = project.ext.react.get("enableHermes", false);

and

if (enableHermes) {
    def hermesPath = "../../node_modules/hermesvm/android/";
    debugImplementation files(hermesPath + "hermes-debug.aar")
    releaseImplementation files(hermesPath + "hermes-release.aar")
  } else {
    implementation jscFlavor
  }

were present.

Crash disappears after cleaning the build:
cd android && ./gradlew clean

[Villar74]

@dov11 cleaning build doesn't help with that for me
P.S. I want to use hermes, so i set it to true

[qadratic]

I, following the guide set enableHermes to true but cant see any global variable named HermesInternal.

same issue here it builds fine but crashes on start up

[Jalson1982]

Same issue after setting:
project.ext.react = [
entryFile: "index.js",
enableHermes: true // clean and rebuild if changing
]
App build fine but crash on startup :
