FirebaseInitProvider: FirebaseApp initialization unsuccessful

What does this mean? What are we doing wrong?

Would assume, that the authentication did not succeed.

a) the buildscript repositories and dependencies for the project level build.gradle:

buildscript { repositories { google() jcenter() } dependencies { // Android Gradle Plugin classpath "com.android.tools.build:gradle:3.3.2" // Google Services Plugin classpath "com.google.gms:google-services:4.2.0" } } 

b) the dependencies for the module level app/build.gradle (the Android Intel x86 images may still have a previous version of the Google Play Services installed, eg. 10.2.0 runs on the current x86 emulator, while eg. 11.8.0 runs on my physical ARM device). referencing play-services and firebase-core will include all of their modules, unless excluding some them. update: one has to reference all the libraries individually now. referencing com.google.android.gms:play‐services and com.google.firebase:firebase-core does not work anymore since 15.0.0.

android { ... buildTypes { debug { // suffixing the package name for debug builds, // in order to partially mute the crash-reporting // is an *optional* configuration (see below): applicationIdSuffix ".debug" } } } dependencies { // Google Play Services // https://developers.google.com/android/guides/releases implementation "com.google.android.gms:play-services-base:15.0.1" implementation "com.google.android.gms:play-services-auth:16.0.0" implementation "com.google.android.gms:play-services-identity:15.0.1" // Google Firebase // https://firebase.google.com/support/release-notes/android implementation "com.google.firebase:firebase-core:16.0.1" implementation "com.google.firebase:firebase-auth:16.0.3" implementation "com.google.firebase:firebase-config:16.0.0" implementation "com.google.firebase:firebase-storage:16.0.1" implementation "com.google.firebase:firebase-database:16.0.1" implementation "com.google.firebase:firebase-messaging:17.3.0" implementation "com.google.firebase:firebase-appindexing:16.0.1" implementation "com.google.firebase:firebase-functions:16.1.0" implementation "com.google.firebase:firebase-invites:16.0.1" // implementation "com.google.firebase:firebase-crash:16.0.1" implementation "com.google.firebase:firebase-ads:15.0.1" implementation "com.google.firebase:firebase-firestore:17.0.4" implementation "com.google.firebase:firebase-perf:16.0.0" // the inapp messaging may cause dependency conflicts: // implementation "com.google.firebase:firebase-inappmessaging:17.0.0" // implementation "com.google.firebase:firebase-inappmessaging-display:17.0.0" } 

c) the bottom line of mobile/build.gradle should be:

// apply the Google Services Plugin apply plugin: "com.google.gms.google-services" 

d) make sure to have the (downloaded) credentials available at app/google-services.json; on the Firebase Console, one has to add both SHA1 (or SHA256) hashes, of the debug and the release keys, in order to have both builds authenticating properly; once it all matches, it should report:

I/FirebaseInitProvider: FirebaseApp initialization successful 

It's all well documented, just see Setup Google Play Services, Firebase Quickstart or Crash Reporting; while I find this article on the Firebase Blog quite useful: Organizing your Firebase-enabled Android app builds, because it explains how to partially mute the crash-reporting. The release notes always announce the updates & changes.

It happens when you dont have apply plugin: 'com.google.gms.google-services' in your app/build.gradle. Try adding it.

Also make sure you have Google Play services SDK installed in Android SDK Manager.

The first thing I would advice you to check on is:

1) Have you included the <uses-permission android:name="android.permission.INTERNET" /> in your Manifest ?

Make sure you have added this line to App level build.gradle file

apply plugin: 'com.google.gms.google-services' 

I too was facing a similar issue. I had imported my Google developer project to Firebase and had done all the steps as given in the instructions in the Android studio app and Firebase console i.e. adding the dependencies, google-services.json file and building again.

It still would not send data to the Firebase console. So, while going through the logcat, Firebase was unable to initialise as the google_app_id seemed to be missing.

After a lot of trial and error, I had to add a new string resource in my res/values/strings.xml file.

 <string name="google_app_id">YOUR_GOOGLE_APP_ID</string> 

The Google App ID is available in the google_services.json file that you have downloaded from the Firebase console under the heading mobilesdk_app_id.

"client": [ { "client_info": { "mobilesdk_app_id": "SOMETHING" } . . . 

Copy the mobilesdk_app_id and paste it into your string resource inside res/values/strings.xml file with the name google_app_id.

Rebuild the code and it should work. :)

Whole problem occure because of two reason:

1. You have not taken permision in mainfest

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <uses-permission android:name="android.permission.INTERNET" /> 

[enter image description here][1]

2. your gradle build version have bug- project level dependency

classpath 'com.google.gms:google-services:4.1.0'

replace with

classpath 'com.google.gms:google-services:4.0.1'

In my case, I did all the things in Gradle properly. Even though it showed FirebaseApp initialization unsuccessful

I added com.google.android.c2dm.permission.RECEIVE permission in manifest which solved my problem.

 <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <uses-permission android:name="android.permission.INTERNET" /> 

In my case I was trying to Selectively compile Google play Services. Instead of using

compile 'com.google.android.gms:play-services:9.4.0' 

as described at: https://developers.google.com/android/guides/setup#ensure_devices_have_the_google_play_services_apk

I manually added maps and some other dependencies module from Google Play Services as

compile 'com.google.android.gms:play-services-maps:9.4.0' compile 'com.google.android.gms:play-services-places:9.4.0' 

Unfourtunately Firebase stoped working after this.

As a result I had to rollback and return to use

compile 'com.google.android.gms:play-services:9.4.0' 

instead of selectively.

I got the same Logcat output.

Fixed it by updating my Google Play Services Dependency to 9.0.0 in my app/build.gradle

and updating

buildScript { //... dependencies { //... classpath 'com.google.gms:google-services:3.0.0' } } 

in my project build.gradle to 3.0.0

In the build.gradle (project level)

change

 classpath 'com.google.gms:google-services:4.1.0' 

to this

 classpath 'com.google.gms:google-services:4.0.1'
