[firebase] Unable to get provider com.google.firebase.provider.FirebaseInitProvider

I am testing the new Crash tool: https://firebase.google.com/docs/crash/

After going through the steps, the app launches and it crashes saying:

I've got this error just on devices with API lower that 21. In my case, I have had to work with a project where multiDexEnabled option in build.gradle was already set to true. I checked dex file from APK and referenced methods number was less than 64k, so project doesn't need to be a multidex one, therefore I set multiDexEnabled to false. This solution worked for me.

Go to android studio setting (by pressing Ctrl+Alt+S in windows), search for Instant Run and uncheck Enable Instant Run.

By disabling Instant Run and running your application again, problem will be resolved.

For react native app, the error was java.lang.RuntimeException: Unable to get provider com.google.firebase.provider.FirebaseInitProvider: java.lang.ClassNotFoundException: Didn't find class "com.google.firebase.provider.FirebaseInitProvider" It was only getting for devices with Android Version < ~4.4

Solved it by just replacing Application in MainApplication.java with MultiDexApplication

NOTE: import android.support.multidex.MultiDexApplication;

I added the following code in proguard file.

-keep public class * extends android.app.Activity_x000D_
-keep public class * extends android.app.Application

and it worked in my case.

In my case, the problem was solved by adding this line to the module build.gradle:

// ADD THIS AT THE BOTTOM

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

Source

Mine was because Firebase SDK in Gradle file was set to a wrong number version.

I removed the Firebase debs from Gradle and re-installed them again using Firebase Assistant

I had the same problem in Pre Lollipop devices. To solve that I did as follows. Meantime I was using multiDex in the project.

1. add this for build.gradle in module: app

multiDexEnabled = true

dexOptions {
    javaMaxHeapSize "4g"
}

2. add this dependancy

compile 'com.android.support:multidex:1.0.1'

3.Then in the MainApplication

public class MainApplication extends MultiDexApplication {

private static MainApplication mainApplication;

@Override
public void onCreate() {
    super.onCreate();
    mainApplication = this;
}

@Override
protected void attachBaseContext(Context context) {
    super.attachBaseContext(context);
    MultiDex.install(this);
}


public static synchronized MainApplication getInstance() {
    return mainApplication;
}
}

4.In the manifests file

<application
    android:allowBackup="true"
    android:name="android.support.multidex.MultiDexApplication"

This works for me. Hope this Helps you too :)

you should be sure

to add this line at your manifest

https://developer.android.com/studio/run/index.html#instant-run

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.multidex.myapplication">
    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>
</manifest>

In my case the problem happened after we migrated to AndroidX. For some reason, app was calling MultiDex.install() with reflection:

    final Class<?> clazz = Class.forName("android.support.multidex.MultiDex");
    final Method method = clazz.getDeclaredMethod("install", Context.class);
    method.invoke(null, this);

I changed package from android.support.multidex.MultiDex to androidx.multidex.MultiDex. It worked.

The accepted answer didn't solve my problem.

If you are using Multidex, your Application should extends MultiDexApplication instead of Application.

MyApplication.java

public class MyApplication extends MultiDexApplication{
     ...
}

AndroidManifest.xml

<application
      android:name="your.package.name.MyApplication"
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      ...
      />

Hope it helps.

Instead of manually adding the package name on the build.gradle, you can do it this way:

first add this line at the beggining

import java.util.regex.Pattern

Then add this on the defaultConfig

android {
    ...
    defaultConfig {
        ...
        applicationId = doExtractStringFromManifest("package")
        ...
    }
    ...
}

And finally add the doExtractStringFromManifest method

def doExtractStringFromManifest(name) {
     def manifestFile = file(android.sourceSets.main.manifest.srcFile)
     def pattern = Pattern.compile(name + "=\"(\\S+)\"")
     def matcher = pattern.matcher(manifestFile.getText())
     matcher.find()
     return matcher.group(1)
}

As there are a lot of Cordova comments on the answer, if you are working with Cordova, you shouldn't really edit the build.gradle yourself, it has a comment at the beggining that say

// GENERATED FILE! DO NOT EDIT!

So, if you are using a Cordova, the best thing you can do is to update to cordova-android 5.1.0 or greater where this changes are already present.

If you get the same problem but already have the applicationId set in build.gradle, you can also try the following:

• in Android Studio: Build > Clean Project
• in other IDEs: Clean, Rebuild, whatever...

I was with the same problem in devices with SDK < 22, but for me the reason is the MultiDex, the MultiDex.install must be in the attachBaseContext method.

If you are using MultiDex, try this:

public class YourApplication extends Application {

    @Override
    protected void attachBaseContext(Context context) {
        super.attachBaseContext(context);
        MultiDex.install(this);
    }
    @Override
    public void onCreate() {
        super.onCreate();
        Realm.init(this); //initialize other plugins 

    }
}

app/build.gradle:

android {

    compileSdkVersion 24
    buildToolsVersion "24.0.2"

    defaultConfig {
        applicationId "com.test.app"
        minSdkVersion 16
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        multiDexEnabled true

    }

    dexOptions {
        javaMaxHeapSize "4g"
    }

....
}

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])

        compile 'com.android.support:appcompat-v7:24.2.1'
        ...
        compile 'com.google.firebase:firebase-messaging:9.6.1'
        compile 'com.google.android.gms:play-services:9.6.1'
        compile 'com.android.support:multidex:1.0.1'

    }
...

Don't include the whole play services library but use the one that you need.Replace the line in your build.gradle:

compile 'com.google.android.gms:play-services:9.6.1'

with the appropriate one from Google Play Services APIs,like for example:

compile 'com.google.android.gms:play-services-gcm:9.6.1'

This should works:

Step1:

defaultConfig {
    applicationId "service.ingreens.com.gpsautoon"
    minSdkVersion 17
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

Step 2:

compile 'com.android.support:multidex:1.0.1'

Step 3: Take another class

public class MyApplication extends MultiDexApplication {
}

Step 4: Add this line on manifest

<application
    android:name="android.support.multidex.MultiDexApplication">
</application>

Add this to your module-level build.gradle :

android {               
defaultConfig {
    ....
    multiDexEnabled true
}
...
}

dependencies {
    compile 'com.android.support:multidex:1.0.1'
    .........
}

If you override Application class then extend it from MultiDexApplication :

YourApplicationClass extends MultiDexApplication

If you cant extend it from MultiDexApplication class then override attachBaseContext() method as following :

protected void attachBaseContext(Context base) {
     super.attachBaseContext(context);
     Multidex.install(this);
  }

And dont run anything before MultiDex.install(this) is executed.

If you dont override the Application class simply edit your manifest file as following :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    .......>
     <application
         ......
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>
    ......
</manifest>

in my case, I forget to add (or deleted accidentally) firebase core in build gradle

implementation 'com.google.firebase:firebase-core:xx.x.x'

I had the same issue and fixed by using project level crashlytics gradle version 2.1.1

classpath 'com.google.firebase:firebase-crashlytics-gradle:2.1.1'
