Multiple dex files define Landroid/support/v4/acce

Question

If I run gradle assembleDebug from the command line, I am suddenly getting this error:

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dx.util.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

If I grep for v4 I see two files inside my build folder.

Binary file build/pre-dexed/debug/support-v4-19.0.0-2ba5fdd60a6c3836b3104a863fe42897da1fa9d1.jar matches
Binary file build/pre-dexed/debug/support-v4-r7-227d905d79b23b20866531d4f700446c040a2ccb.jar matches

My gradle file includes only this support library:

compile 'com.android.support:support-v13:19.0.0'

I am stumped as to how the r7 library is included somehow. I've run gradle clean and it always appears there when I rerun assembleDebug.

If I grep for r7 inside the build directory, I see it inside the file:

Binary file build/exploded-bundles/ComGoogleAndroidGmsPlayServices4030.aar/classes.jar matches

If I don't include v13, then other things don't compile.

But doesn't v13 include v4 support library?

Is this an incompatibility between play services AAR bundle and the v13 library?

I grabbed the gradle file from gradleplease.appspot.com.

Removing play services does not fix it; same error.

My dependencies inside build.gradle:

 dependencies {


 // Google Play Services
//compile 'com.google.android.gms:play-services:4.0.30'

// Support Libraries
//compile 'com.android.support:support-v4:19.0.0'
///compile 'com.android.support:appcompat-v7:19.0.0'
//compile 'com.android.support:gridlayout-v7:19.0.0'
compile 'com.android.support:support-v13:19.0.0'
compile 'org.eclipse.mylyn.github:org.eclipse.egit.github.core:2.1.5'
compile 'commons-codec:commons-codec:1.9'
compile 'com.madgag:markdownj-core:0.4.1'
compile 'com.wu-man:android-oauth-client:0.0.2'
compile 'com.google.http-client:google-http-client-jackson2:1.17.0-rc'
compile 'org.apache.commons:commons-lang3:3.2'
compile 'com.google.code.gson:gson:2.2.4'
}

Answer 1

I solved similar error by adding following piece of code to my build.gradle file inside the android block.

android {
    dexOptions {
        preDexLibraries = false
    }
}

Answer 2

I had the same error on a legacy project. My fault was that the support-library was included twice: Once inside google-play-services lib, and another as standalone.

This is how I fixed it:

BAD build.gradle:

dependencies {
   compile files('libs/android-support-v4.jar') 
   compile files('libs/core-2.2.jar')
   compile files('libs/universal-image-loader-1.8.5-with-sources.jar')
   compile 'com.google.android.gms:play-services:3.2.65'
}

GOOD build.gradle:

dependencies {
   // compile files('libs/android-support-v4.jar')  // not needed 
   compile files('libs/core-2.2.jar')
   compile files('libs/universal-image-loader-1.8.5-with-sources.jar')
   compile 'com.google.android.gms:play-services:3.2.65'
}

Hope it helps someone :-)

Answer 3

I'm using com.google.android.gms:play-services-analytics:8.3.0 and android-support-v13.jar and could not get exclude module: 'support-v4' to work.

What worked for me was using the android-support-v13 artefact rather than the android-support-v13.jar file.

I.e. instead of

dependencies {
compile ('com.google.android.gms:play-services-analytics:8.3.0')
compile files('libs/android-support-v13.jar')

}

I used

dependencies {
compile ('com.google.android.gms:play-services-analytics:8.3.0')
compile ('com.google.android:android-support-v13')

}

Also to note you can see your android dependencies, by going to your Android Studio Gradle view, and selecting the target "androidDependencies".

One more tip: I was having this issue, until I removed the v4 support lib from the libs folder in both the project and my related module/library project(s).

A similar dex issue resolved method

gradle.build was containing:

compile files('libs/httpclient-4.2.1.jar')
compile 'org.apache.httpcomponents:httpclient:4.5'
compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'

The issue was resolved when i removed

compile files('libs/httpclient-4.2.1.jar') 

My gradle now looks like:

apply plugin: 'com.android.application'

android {

compileSdkVersion 24
buildToolsVersion "24.0.3"

defaultConfig {
    applicationId "com.mmm.ll"
    minSdkVersion 16
    targetSdkVersion 24
    useLibrary  'org.apache.http.legacy'
}

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

dependencies {

compile 'com.google.android.gms:play-services:6.1.+'
compile files('libs/PayPalAndroidSDK.jar')
compile files('libs/ksoap2-android-assembly-3.0.0-RC.4-jar-with-dependencies.jar')
compile files('libs/picasso-2.1.1.jar')
compile files('libs/gcm.jar')
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'org.apache.httpcomponents:httpclient:4.5'
compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'
}

There was a redundancy in the JAR file and the compiled gradle project

So keenly look for dependency and jar files having same classes.

And remove redundancy.
This worked for me.

Answer 6

I've had the same issue. In my project, I had the following dependencies :

• appcompat-v7
• android-support-v13

For legacy reasons, the appcompat was fetched from the Google Maven repo, whereas the android-support was a local .jar.

When I figured out this, and replaced this local reference with a maven reference, it just solved my build issue.

Here's the diff of my app/build.gradle :
