Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat

Question

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

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dx.util.DexEx         


        

Answer 1

Deleting all files from Gradle cache fixed my problem.

on Linux:

rm -rf ~/.gradle/caches/*

Answer 2

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).

Answer 3

I started getting this error when upgrading to ButterKnife 8.5.1. None of the other answers here worked for me.

I used gradle -q :app:dependencies to see the tree, and then looked through jar files until I found the conflict. The conflict was that butterknife's dependency on com.android.support:support-compat:25.1.0 contains a version of the accessibility class, and com.android.support:support-v4:23.1.1 also contains the class.

I solved it by changing my dependency from this:

compile 'com.jakewharton:butterknife:8.5.1'

to this:

compile('com.jakewharton:butterknife:8.5.1') {
    exclude module: 'support-compat'
}

It doesn't seem to affect ButterKnife's operation so far.

Edit: There is a better solution, which was to upgrade my android support libraries to match ButterKnife's:

compile('com.android.support:appcompat-v7:25.2.0')
compile('com.android.support:design:25.2.0')
compile 'com.jakewharton:butterknife:8.5.1'

Answer 4

In case anyone finds out that the answer from CommonsWare could not be applied to android library project, here is the snippet to fix

compile (project(':yourAndroidLibrary')){ exclude module: 'support-v13' }

You will find problems

Unsupported Gradle DSL method found: 'exclude()'

if you use compile project(':yourAndroidLibrary'){ exclude module: 'support-v13' }

The differences are the bracelet "(" and ")" before "project".

Answer 5

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')

}

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.
