Answer 1

enable multidex as following:

android {    
    defaultConfig {
        // Enabling multidex support.
        multiDexEnabled true
    }  
}
dependencies {
    // add dependencies for multidex
    compile 'com.android.support:multidex:1.0.1'
}

create one class like this

public class Multi_Dex extends Application {
    @Override
    protected void attachBaseContext(Context context) {
        super.attachBaseContext(context);
        MultiDex.install(this);
    }
}

now in your manifiest file add this

<application
    android:name=".Multi_Dex" <!-- this line enable multi-dex application -->
    android:allowBackup="true" <!-- rest of them doesen't matter to enable multi-dex -->
    android:icon="@drawable/logo"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

Answer 2

There was no issue with MultiDex library support. The main problem was with version of google.gms play-services.

compile 'com.google.android.gms:play-services-analytics:11.0.1'
compile 'com.google.android.gms:play-services-gcm:11.0.1'

which made the app to crash. All I had to was to update my google services via the android sdk manager. Then change the version number from 11.0.1 to 11.0.4. This was just the plugin version issue which crashed the app and muddled error messages.
