Twitter Fabric +MultiDex causes NoClassDefFoundError

Question

I have enable Multidex support in my project and it was working fine on Android 5.0 and above, But when I started testing my app with Android 4.3 and below it start giving me NoClassDefFoundError for TwitterConfig.

I can't disable my Multidex support. I am not getting why I am getting this issue. Tried to find out solution on net but didn't help.

Here is Exception which I am getting.

    buildscript {

    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
 }

    apply plugin: 'com.android.application'
    apply plugin: 'io.fabric'

  repositories {

        transitive = true;
    }
    compile('com.twitter.sdk.android:twitter:1.8.0@aar') {
        transitive = true;
    }
}

Here is my Twitter Code in MyApplication class.

@Override
public void onCreate() {
    super.onCreate();

    //Configure twitter using Twitter key and Secret Key
    TwitterAuthConfig authConfig =
            new TwitterAuthConfig(TWITTER_KEY,
                    TWITTER_SECRET);

    // add functionalities which we are using with Fabric
    Fabric.with(this, new Crashlytics(), new Twitter(authConfig));

    FacebookSdk.sdkInitialize(getApplicationContext());
    // Initialize the SDK before executing any other operations,
    // especially, if you're using Facebook UI elements.

}

Even i tried this solution too but didn't help.

Any hint or reference appreciated.

Multidex support for Android 5.0 and higher

Android 5.0 and higher uses a runtime called ART which natively supports loading multiple dex files from application APK files. ART performs pre-compilation at application install time which scans for classes(..N).dex files and compiles them into a single .oat file for execution by the Android device. For more information on the Android 5.0 runtime, see Introducing ART.

That means your app would working fine on API level 21 or above.

Multidex support prior to Android 5.0

Versions of the platform prior to Android 5.0 use the Dalvik runtime for executing app code. By default, Dalvik limits apps to a single classes.dex bytecode file per APK. In order to get around this limitation, you can use the multidex support library, which becomes part of the primary DEX file of your app and then manages access to the additional DEX files and the code they contain.

So, Firstly making sure you have imported correct dependency, which It seems you did it.

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

In your manifest add the MultiDexApplication class from the multidex support library to the application element.

<?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>

Alternative to that, If your app extends the Application class, you can override the attachBaseContext() method and call MultiDex.install(this) to enable multidex.

public void onCreate(Bundle arguments) {
    MultiDex.install(getTargetContext());
    super.onCreate(arguments);
    ...
}

Finally, you will need to update your build.gradle file as below by adding multiDexEnabled true :

defaultConfig {  
        applicationId '{Project Name}'  
        minSdkVersion 15  
        targetSdkVersion 23  
        versionCode 1  
        versionName "1.0"  
        multiDexEnabled true  
    }  

I hope it will help you out.

I've solved the problem by setting fabric gradle plugin version manually to lower version '1.21.6'. Probably there was some issue with the latest one, which in my case was '1.23.0'. (Fabric plugin version history)

So I set

dependencies {
        classpath 'io.fabric.tools:gradle:1.21.6'
    }

instead of

dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
