The number of method references in a .dex file exceed 64K

Question

Currently working on my android application after including play services and firebase library in my project I'm getting this error and unable to run my code

:app:prePackageMarkerForDebug :app:transformClassesWithDexForDebug To run dex in process, the Gradle daemon needs a larger heap. It currently has approximately 910 MB. For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB. To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties. For more information see https://docs.gradle.org/current/userguide/build_environment.html Error:The number of method references in a .dex file cannot exceed 64K. Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html :app:transformClassesWithDexForDebug FAILED 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.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/bin/java'' finished with non-zero exit value 2

My build.gradle file is here :

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "xyz.in.network"
    minSdkVersion 16
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        shrinkResources true
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        multiDexEnabled true
    }
}
}

dependencies {
   compile fileTree(dir: 'libs', include: ['*.jar'])
   testCompile 'junit:junit:4.12'
   compile project(':libs:ViewPagerIndicator')
   compile 'com.google.android.gms:play-services:9.0.0'
   compile 'com.android.support:appcompat-v7:23.4.0'
   compile 'com.android.support:design:23.4.0'
   compile 'com.google.android.gms:play-services-maps:9.0.0'
   compile 'com.google.android.gms:play-services-location:9.0.0'
   compile 'com.android.support:cardview-v7:23.4.0'
   compile 'com.getbase:floatingactionbutton:1.10.1'
   compile 'com.squareup.picasso:picasso:2.5.2'
   compile 'com.android.volley:volley:1.0.0'
   compile 'com.google.firebase:firebase-messaging:9.0.0'
   compile 'com.android.support:multidex:1.0.1'
   }

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

And my manifestfile is here

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:name="android.support.multidex.MultiDexApplication"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
<activity android:name=".Util.DisconnectedNetwork"
        android:screenOrientation="portrait"
        android:theme="@style/Theme.Transparent"></activity>

    <service android:name=".FCM.FirebaseMessagingHandler">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT"/>
        </intent-filter>
    </service>

    <service android:name=".FCM.FirebaseRegistrationTokenHandler">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
        </intent-filter>
    </service>

    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

</application>

After increasing the heap size to 2048M. Gradle give this 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.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536

I follow all the instruction given on android developer site but still got this problem. How to solve this problem?

Answer 1

You need to enable multidex in the android default config then:

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.3'

    defaultConfig {
        applicationId "com.example.case"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 43
        versionName "4.0.13"

        // Enabling multidex support.
        multiDexEnabled true
    }

When you are building you application in a daily routine, you normally use the debug default flavor. So if you application has more than 65k method, you need ot enable it on all flavor.

As a side note, you may want to use Proguard on the debug build so you won't have to enable multiDex on it.

Full app/build.gradle (documentation)

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.0"

    defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

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

Last part: add the MultiDex application in the manifest (or as a parent of your own Application

<?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>
