Hi Evollu,

I'm having a new issue with the component that crashes the Android app. The fatal error displayed on Logcat when this occurs is:

06-05 18:49:14.678 5460-5460/airix.mobile I/zygote: Rejecting re-init on previously-failed class java.lang.Class: java.lang.IllegalAccessError: Class com.google.android.gms.internal.zzbfm extended by class com.google.firebase.messaging.RemoteMessage is inaccessible (declaration of 'com.google.firebase.messaging.RemoteMessage' appears in /data/app/airix.mobile-cCi2-cSxqp3WdSwbOUicpg==/split_lib_dependencies_apk.apk)

I've checked and all the imports seem to be as suggested by you on your readme. Would you have any ideas or any clues? I'm not finding similar errors online anywhere.

Thanks very much.

Sorry, this is actually my bad. It was related to not importing a non-deprecated version of firebase cloud messaging. Very confusing stuff.

@404sand808s, Can you mention the correct imports?

[jamesjara]

4 days reading gradle, updating dependencies like a crazy, my solution if it works for anybody there @ruk91
android/build.gradle

buildscript { 
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.1'
        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

android/app/build.gradle

dependencies { 
    // ....

    // Push notifications FCM
    compile project(':react-native-fcm')
    // Firebase dependencies <HERE>
    implementation "com.google.android.gms:play-services-base:15.0.1"
    implementation "com.google.firebase:firebase-core:15.0.2"
    implementation "com.google.firebase:firebase-messaging:15.0.2"

    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "com.android.support:appcompat-v7:26.0.1"
    compile ('com.facebook.react:react-native:0.46.4') { force = true } // super hack! From node_modules
}
