If you have applied proguard rules then add below line in ProGuard Rules

-keep class com.google.firebase.provider.FirebaseInitProvider

and its solve my problem.

I too faced the same issue and finally solved it by disabling Instant Run in an android studio      Settings   Build  Execution  Deployment   Instant Run and uncheck Enable Instant Run   Update   There is no Instant Run option available in latest Android Studio 3 5   It should be applicable only for older versions

When your app and the libraries it references exceed 65 536 methods  you encounter a build error that indicates your app has reached the   limit of the Android build architecture      To avoid this limitation you have to configure your app for multidex   If your minSdkVersion is set to 21 or higher  all you need to do is  set multiDexEnabled to true in your module-level build gradle file  as  shown here    android       defaultConfig                       minSdkVersion 21          multiDexEnabled true                       Else  if your minSdkVersion is set to 20 or lower  then you must  use the multidex support library as follows      1 Modify the module-level build gradle file to enable multidex and add the multidex library as a dependency  as shown here   android       defaultConfig                       minSdkVersion 15          multiDexEnabled true                   dependencies           implementation  com android support multidex 1 0 3          2 Depending on whether you override the Application class  perform one of the following          If you do not override the Application class  edit your manifest file to set android name in the  tag as follows                 lt application         android name  android support multidex MultiDexApplication   gt                   lt  application gt           Else If you do override the Application class  change it to extend MultiDexApplication  if possible  as follows               public class MyApplication extends MultiDexApplication                  Else you do override the Application class but it s not possible to change the base class  then you can instead override the   attachBaseContext   method and call MultiDex install this  to enable   multidex               public class MyApplication extends SomeOtherApplication         Override      protected void attachBaseContext Context base            super attachBaseContext base           MultiDex install this

I had the same issue and solved just add a piece of code  If you are getting this issue means you had already completed all the steps that need to use Firebase  You just need to create a class that extends the Application  public class Application CrashReport extends Application   and add this class in mainifest file and In that class just override the  below method      Override protected void attachBaseContext Context base        super attachBaseContext base       and add  MultiDex install this   in that method means     Override protected void attachBaseContext Context base        super attachBaseContext base       MultiDex install this       Note  - Don t forget to follow above steps

If you have   20 minsdkversion  you need to use the latest Firebase Auth version i e       implementation  com google firebase firebase-auth 18 1 0    and no need to setup multi-dex if you don t actually need it   I encountered this issue when I ve used 16 0 5 from the Firebase helper but was able to fix it when I ve updated to 18 1 0

First add the following into build gradle Module app ----   defaultConfig     multiDexEnabled true          Then in same file add the following  dependencies      compile  com android support multidex 1 0 1            Then in AndroidManifest xml write the following   lt application     android name  android support multidex MultiDexApplication                       lt  application gt    That s it  It will definitely work

If you re using Xamarin Forms you might want to check out Didn  39 t find class  quot com google firebase provider FirebaseInitProvider quot   as this captures the issue with the dex error with google firebase on startup  unresolved at this time    I ve reverted to using no shrinking in the short-term and plan to use ProGuard until R8 is more stable

I had the same problem in my  YouTube player project     and the following solved the problem for me    Add this code into your build gradle  module  app  inside defaultConfing   defaultConfig                         multiDexEnabled   true    Add this code into your build gradle  module  app  inside dependencies   dependencies       compile  com android support multidex 1 0 1                         Open AndroidManifest xml and within application    lt application     android name  android support multidex MultiDexApplication                       lt  application gt    or if you have your App class  extend it from MultiDexApplication like   public class MyApp extends MultiDexApplication            And finally  I think you should have Android Support Repository downloaded  in the Extras in SDK Manager

Enabling multidex is not a good solution because multidexhave another usage in android see this answer what is multidex   The solution is disabling instant run as  Shylendra Madda said     Settings   Build  Execution  Deployment   Instant Run and uncheck Enable Instant Run   I think the reason of this problem is when instant run is enabled  Android Studio don t put libraries such as firebase into generated apk to decreasing project build time because firebase  library and other libraries such as maps and others is exist in play services and play services is installed on android device so if instant run enabled don t need to put them in generated apk to make build time faster   So when you extract apk and install it on another device you will see this exception

I had the same error and I solved it with MultiDex  like described on this link    https   developer android com studio build multidex html    Sometimes it is not enough just to enable MultiDex      If any class that s required during startup is not provided in the primary DEX file  then your app crashes with the error java lang NoClassDefFoundError    https   developer android com studio build multidex keep   FirebaseInitProvider is required during startup   So you must manually specify FirebaseInitProvider as required in the primary DEX file   build gradle file  android       buildTypes           release               multiDexKeepFile file  multidex-config txt                                       multidex-config txt  in the same directory as the build gradle file   com google firebase provider FirebaseInitProvider class

This issue occurred when I switched to Android Studio 3 4 with Android Gradle plugin 3 4 0  which works with the R8 compiler   The Android Gradle plugin includes additional predefined ProGuard rules files  but it is recommended that you use proguard-android-optimize txt  More info here   buildTypes       release           minifyEnabled true         proguardFiles getDefaultProguardFile             proguard-android-optimize txt                 List additional ProGuard rules for the given build type here  By default               Android Studio creates and includes an empty rules file for you  located              at the root directory of each module              proguard-rules pro

1  Go to the gradle enable multiDexEnabled and add the multidex library in the dependencies   android             defaultConfig         multiDexEnabled true                   dependencies        add dependency    implementation  com android support multidex 1 0 1      2  Go to the Manifest file and write android name   MyApplication   Class name MyApplication  is optional you can write whatever you want          lt application         android name   MyApplication          android allowBackup  true          android icon   mipmap ic launcher          android label   string app name          android supportsRtl  true          android theme   style AppTheme  gt                                                         lt  application gt    3  As you wrote android name   MyApplication  Inside Application at Manifest file  it will give you an error because you didn t create MyApplication class  Create MyApplication Class extend it by  application  class or Simply click on MyApplication  a small red balloon appear on the left side of a syntax click on it  you will see  create MyApplication class  in the menu  click on it and Include below Method Inside that class       public class MyApplication extends Application         Override      protected void attachBaseContext Context base            super attachBaseContext base           MultiDex install this            If you want to get more information then Click on this Link  https   developer android com studio build multidex html   Hopefully  It works for you

As mentioned previously  this is a problem with multidex  you should add implementation to your build gradle and MainApplication java  But what you add really depends on whether you support AndroidX or not  Here is what you need to solve this problem    If you support AndroidX   Put these lines of code into your build gradle  android app build gradle    defaultConfig     applicationId  com your application    versionCode 1   versionName  1 0          multiDexEnabled true     lt -- THIS LINE           dependencies           implementation  androidx multidex multidex 2 0 1      lt -- THIS LINE           Put these lines into your MainApplication java  android app src main java     MainApplication java    package com your package   import androidx multidex MultiDexApplication      lt -- THIS LINE         public class MainApplication extends MultiDexApplication             lt -- THIS LINE    If you don t support AndroidX   Put these lines of code into your build gradle  android app build gradle    defaultConfig     applicationId  com your application    versionCode 1   versionName  1 0          multiDexEnabled true     lt -- THIS LINE           dependencies           implementation  com android support multidex 1 0 3      lt -- THIS LINE           Put these lines into your MainApplication java  android app src main java     MainApplication java    package com your package   import android support multidex MultiDex       lt -- THIS LINE         public class MainApplication extends MultiDexApplication             lt -- THIS LINE

This is a bit late for those coming in  but check your proguard rules  I wasted a lot of time on this  Your proguard rules could be changing the names to important firebase files  This really only proves a problem in production and instant run     proguard-rules pro  -keep class com google firebase           -keep class com firebase           -keep class org apache           -keepnames class com fasterxml jackson           -keepnames class javax servlet           -keepnames class org ietf jgss           -dontwarn org apache    -dontwarn org w3c dom
