Answer 1

You will have to exclude libraries which are causing this issue. For Example: -

compile('org.simpleframework:simple-xml:2.7.+'){
    exclude module: 'stax'
    exclude module: 'stax-api'
    exclude module: 'xpp3'
}

Answer 2

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
    }
}

Answer 3

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

does not work proper,and get the error:

Could not get unknown property 'com' for object of type com.android.build.gradle.AppExtension.

I solve the problem by adding this to android block.

dexOptions {
    preDexLibraries = false
    additionalParameters=['--core-library']
}

Hoping this is helpful to you!

Answer 4

I think we cannot enable --core-library via dexOptions.

We know that dexOptions delegated to a com.android.build.gradle.internal.dsl.DexOptions object, which implements com.android.builder.core.DexOptions.

From the source code, we know it doesn't support --core-library.

From Issue 79280: dexOptions in gradle plugin don't support coreLibrary

You can do it manually by

• disable pre-dexing (this is because our cache would have issues if we allow adding extra params)
• modify the Dex tasks to add --core-library as an extra parameters.

Answer 5

I solved this problem! Unfortunately I solved it only by installing version Android Studio 0.4.2.... Other methods didn't help... Probably, later, it is better to configure project for new version of Android Studio.

Answer 6

Hi I have the same problem and I resolved it by checked the box "Add --core-library" in /Preferences/Compiler/Android Compilers
