I've tried a lot of solutions but nothing helped.

Answer 1

changed latest firebase-messaging google dependencies and modified other dependencies also in a same version in app gradle file. working fine now

dependencies version detail you can refer here

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
    implementation 'com.google.firebase:firebase-auth:17.0.0'
    implementation 'com.google.firebase:firebase-messaging:18.0.0'
}

Answer 2

There is probably some problem with the dependencies involved.

In my case, making the following changes worked perfectly in the app level build.gradle

dependencies{
     implementation 'com.google.firebase:firebase-auth:17.0.0'
     implementation 'com.firebaseui:firebase-ui-database:6.0.2'
     ...
}

Answer 3

In my case I forgot to comment Database Package in MainApplication.java

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
        new MainReactPackage(),
            new AsyncStoragePackage(),
            new RNCameraPackage(),
            new VectorIconsPackage(),
            new RNGestureHandlerPackage(),
        new RNFirebasePackage(),
        // add/remove these packages as appropriate
        //new RNFirebaseAdMobPackage(),
        new RNFirebaseAnalyticsPackage(),
        //new RNFirebaseAuthPackage(),
        // new RNFirebaseRemoteConfigPackage(),
        new RNFirebaseCrashlyticsPackage(),
        // new RNFirebaseDatabasePackage(), <==== Comment this package
       // new RNFirebaseFirestorePackage(),
        // new RNFirebaseFunctionsPackage(),
        new RNFirebaseInstanceIdPackage(),
       // new RNFirebaseInvitesPackage(),
        new RNFirebaseLinksPackage(),
        new RNFirebaseMessagingPackage(),
        new RNFirebaseNotificationsPackage(),
        new RNFirebasePerformancePackage()
       // new RNFirebaseStoragePackage()
      );
    }

Answer 4

Faced the same issue. Then I found out that I missed an important set of instructions to integrate Firebase with Android project: https://firebase.google.com/docs/android/setup#add_firebase_to_your_app

Here is the summary of the steps in that documentation that helped in my case:

1. Generate google-services.json and put it to your android/app/ directory.
2. Add classpath 'com.google.gms:google-services:4.1.0' to buildscript -> dependencies section of your root-level build.gradle config; add google() to allprogects -> repositories section of the same file.
3. Add implementation 'com.google.firebase:firebase-core:16.0.3' to dependencies section of your app module's build.gradle file; add apply plugin: 'com.google.gms.google-services' at the very bottom of the same file.
4. Sync and rebuild. Now it should work.

Answer 5

I have faced the same issues. You have to change the react-native-firebase version in pakage.json file. I found the solution from here

here

Answer 6

In the gradle.properties file, try adding::

android.enableJetifier = true
android.useAndroidX = true
