Question

I am using external libraries payu money sdk and linkedin-sdk, both uses volley libraries, which while compiling project gives duplicate entry of AuthFailureError.class

Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'.

java.util.zip.ZipException: duplicate entry: com/android/volley/AuthFailureError.class"

i have also added following code to exclude module, but still same error

configurations{ all*.exclude module: 'com.android.volley' }

please help

Answer 1

I stumbled upon this same error, and after reading this, I was able to solve it.

Try adding this line inside your app dir build.gradle file -

android{
configurations {
    all*.exclude group: 'com.android.volley'
}}

Hope this helps.

Answer 2

I had this problem when I tried to generate the APK (release) and I solved it changing the linkedin-sdk build.gradle:

From:

dependencies {
    compile 'com.android.support:support-annotations:20.0.0'
    compile 'com.android.support:support-v4:21.0.+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile files('libs/volley.jar')
    androidTestCompile('junit:junit:4.12') }

To:

dependencies {
    compile 'com.android.support:support-annotations:20.0.0'
    compile 'com.android.support:support-v4:21.0.+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.volley:volley:1.0.0'
    androidTestCompile('junit:junit:4.12') }

Add multiDexEnabled true in the defaultConfig section of your gradle file

Then,

compile 'com.android.support:multidex:1.0.1' in your dependencies

Finally add below in your application class:

 @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }

Also, check if you are using volley.jar in your libs folder. If so, delete that jar file, and compile again. Sometimes, jar dependencies conflicts with those compiled using remote source.

Answer 4

just remove the duplicate jar file(note:use new version,delete old version) for importing "com.android.volley.AuthFailureError" in build.gradle. Then clean project and rebuild project and then run you will get result.

Answer 5

This is an example how to exclude classes in dependencies when there is duplicate entry in gradle.

 compile ('com.google.api-client:google-api-client-android:1.17.0-rc') {
    exclude module: 'httpclient'
 }

or try with your way just add some more text

configurations {
     all*.exclude group: 'com.android.support', module: 'support-v4'
}

So, now what you have to do is

Search CTRL+SHIFT+N in android studio for the class AuthFailureError.class See which jar contains this and remove it like above (This is just as an example/You have to figure out the duplicate class and manually remove it)

Answer 6

I had the similar issue while making build on Jenkins, weirdly it was working fine on my local machine. After adding below exclude it worked both on local machine and Jenkins.

android{
configurations {
    all*.exclude group: 'com.android.volley'
}}

I have added configurations block to my app's build.gradle inside android section.

If it matter's Compile SDK version is 22 and Build Tools version is 25.0.0

This worked like a charm.

Answer 7

Okay I got my answer

On mac instead of control n, it is command 0 and the command i needed was

configurations { all*.exclude module: 'volley-release' }

Answer 8

Just remove your volley library from dependancy. Try clean and rebuild project it works for me. Ex. payusdk are also implementing volley library so that is the reason exception shows duplicate entry. I hope it works. because i also found this error and i do these things it works. Thanks.

Answer 9

Use the below command in Android studio terminal to get the dependency conflict data - [Replace with your app Name]

./gradlew -q :<app>:dependencyInsight --dependency volley --configuration compile

If you are using latest Volley library from android [https://github.com/google/volley/releases], add below two lines in your build.gradle file under each of the compile library entries that has conflict.

Ex:

compile('com.xyz:abc:1.1.0-RELEASE') {
        exclude module: 'library'
        exclude group: 'com.mcxiaoke.volley'
}
