UnsatisfiedLinkError when calling Realm.open

[MSVhora]

How frequently does the bug occur?

Sometimes

Description

I have setup realm in one of our module. For some of our users, we are getting this error in our Firebase Crashlytics. App crashes because of this error. I haven't been able to reproduce the issue on my test devices. Although the occurrence of this issue is smaller in number, but app crashes because of it.

I have setup realm with Hilt.

@Provides
@Singleton
fun providesRealm(): Realm {
    return Realm.open(
        configuration = RealmConfiguration.Builder(
            schema = setOf(
                Data::class,
            )
        ).apply {
            schemaVersion(2)
            deleteRealmIfMigrationNeeded()
        }.build()
    )
}

App crashes when app tries to open Realm.

For the error it seems that the native component has not been loaded by when you try to initialize the Realm.

I understand that this error appeared when you introduced this new module. Could you share some details on how this module is set up or, even better, a sample project with a setup similar to yours?

[MSVhora]

Its a usual android multi module setup.

• Startup Initializers are setup in the project
• Realm is being used in one of the module, its instance is provided via Hilt

Will create a sample project with similar setup once I get some free time

[clementetb]

This report, similar to this one, has been fixed with this workaround.

@MSVhora Could you try adding the following snippet in your App onCreate lifecycle callback?

AppInitializer.getInstance(this)
    .initializeComponent(RealmInitializer::class.java)

[MSVhora]

Sorry for the late response, I have tried this as well, but still seeing crashes

[clementetb]

The issue is with the initializers. Your app is trying to perform some operations on Realm and Realm not being initialized.

Please check the component initialization order. You might find more info in this issue comment.
