Android Multiple dex files define Lcom/google/android/gms/common/api/zza

Question

Building project and deploying app to the emulator with API level 22 or 25 goes ok, but when i try to build APK or deploy app to my real device with API level 16 i get the following error:

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/common/api/zza;

My project build.gradle file:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'me.tatarka:gradle-retrolambda:3.3.0-beta4'
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

My app build.gradle file:

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'me.tatarka.retrolambda'
apply plugin: 'com.google.gms.google-services'

    compileSdkVersion 25
    buildToolsVersion "25.0.1"

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

}

dependencies {

    final LEAKCANARY_VERSION = '1.4'
    final FIREBASE_VERSION = '10.0.0'
    final FIREBASE_UI_VERSION = '1.0.0'

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

    compile "com.jakewharton.timber:timber:$TIMBER_VERISON"

    debugCompile "com.squareup.leakcanary:leakcanary-android:$LEAKCANARY_VERSION"

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    testCompile 'junit:junit:4.12'
}

Note: if i add the "multiDexEnabled true" line to my defaultConfig i'll get the following error:

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.

Answer 1

Move this:

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

to the bottom of your app/build.gradle file.
