Java.util.zip.ZipException: duplicate entry: android / support / v7 / graphics / drawable / DrawableUtils.class

I just updated my support library from 23.0.0 to 23.1.0, and now when I create the project, I get this error:

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. > com.android.build.transform.api.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v7/graphics/drawable/DrawableUtils.class

Here is my build.gradle application level:

 buildscript { repositories { maven { url 'https://maven.fabric.io/public' } } dependencies { classpath 'io.fabric.tools:gradle:1.+' } } apply plugin: 'com.android.application' apply plugin: 'io.fabric' apply plugin: 'com.google.gms.google-services' android { compileSdkVersion 23 buildToolsVersion "23" defaultConfig { applicationId 'com.galleri5.android' multiDexEnabled true minSdkVersion 16 targetSdkVersion 23 versionCode 6 versionName "0.6" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } repositories { mavenCentral() mavenLocal() jcenter() maven { url 'https://maven.fabric.io/public' } } dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile 'com.android.support:appcompat-v7:23.1.0' compile 'com.android.support:support-v4:23.1.0' compile 'com.squareup.picasso:picasso:2.5.2' compile 'com.android.support:design:23.1.0' compile 'com.facebook.android:facebook-android-sdk:4.3.0' compile 'com.etsy.android.grid:library:1.0.5' compile 'com.squareup.okhttp:okhttp:2.4.0' compile 'com.squareup.okhttp:okhttp-urlconnection:2.4.0' compile 'com.android.support:recyclerview-v7:23.1.0' compile 'com.android.support:cardview-v7:23.1.0' compile 'com.squareup.retrofit:retrofit:1.9.0' compile 'com.jakewharton:butterknife:7.0.1' compile 'com.github.clans:fab:1.6.1' compile 'uk.co.chrisjenx:calligraphy:2.1.0' compile 'com.google.android.gms:play-services-analytics:8.1.0' compile('com.crashlytics.sdk.android:crashlytics: 2.5.2@aar ') { transitive = true; } }

What will I get this error? I want to use the latest support library. How can I fix this problem? I read this SO thread and this solution did not work. This gave more errors in my code base. In addition, I do not use JAR. Any help would be greatly appreciated. Thanks.

I ran into the same issue in my Android React Native project, and this made it work for me:

 cd android ./gradlew clean

You need to add an exception group: to your V7 support, like this one:

 compile ('com.android.support:appcompat-v7:19.+' ) { exclude group: 'org.apache.httpcomponents', module: 'httpclient' exclude group: 'com.android.support' }
