I am getting the below exception on app launch.

java.lang.RuntimeException: Unable to get provider com.google.firebase.provider.FirebaseInitProvider: java.lang.ClassNotFoundException: Didn't find class "com.google.firebase.provider.FirebaseInitProvider" on path: DexPathList[[zip file "/data/app/com.vfirst.ifbagro-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.vfirst.ifbagro-1, /vendor/lib, /system/lib]]

Here is the the app level build.gradle

apply plugin: 'com.android.application'
apply plugin: 'android-apt' 

android {
compileSdkVersion 24
buildToolsVersion "24.0.1"

defaultConfig {
    applicationId "com.vfirst.ifbagro"
    minSdkVersion 17
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

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


compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.android.support:design:24.2.1'
compile 'com.android.support:support-v4:24.2.1'
compile 'com.google.android.gms:play-services-gcm:9.4.0'
compile 'com.google.android.gms:play-services-location:9.4.0'
compile 'com.android.support:multidex:1.0.1'
compile 'com.google.firebase:firebase-messaging:9.4.0'
compile 'com.google.android.gms:play-services:9.4.0'
testCompile 'junit:junit:4.12'
}

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

This is my application level build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
repositories {
    jcenter()
    mavenCentral()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.2.0'
    classpath 'com.google.gms:google-services:3.0.0'
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    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
}
}

allprojects {
repositories {
    jcenter()
}
}

task clean(type: Delete) {
     delete rootProject.buildDir
}

How to solve the issue?
