Answer 1

In Android Studio 1.1.0, navigate to :

File --> Other Settings --> Default Settings --> Compilers --> Android Compilers

You will find the check-box to Add "--core-library" flag, but this does not seem to be working.

Instead editing the file app/build.gradle

Disabling pre-dexing inside android {} using

dexOptions {
    preDexLibraries = false
}

and modifying Dex task using

project.tasks.withType(com.android.build.gradle.tasks.Dex) {
    additionalParameters=['--core-library']
}

solves the problem.

Edit: Full contents of app/build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "appId"
        minSdkVersion 19
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    dexOptions {
        preDexLibraries = false
        javaMaxHeapSize "4g"
    }

    project.tasks.withType(com.android.build.gradle.tasks.Dex) {
        additionalParameters=['--core-library']
    }

    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/MANIFEST.MF'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE.txt'
        // more exclude files here if conflicts
    }
}
