getting an issue while archiving opentok audio/video chat

Question

I am trying to configure audio/video chat and archive audio/video chat with OpenTok API. I have successfully configure audio/video chat with OpenTok but unable to perform archive.

Getting following issue:

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

java.util.zip.ZipException: duplicate entry: org/apache/commons/collections/ArrayStack.class

This is my library:

Following are my dependencies:

dependencies {

    //compile project(':androidConferenceWebRTC')
    compile project(':countryPicker')
    compile project(':customEmoji')
    compile project(':sugar')
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile('com.crashlytics.sdk.android:crashlytics:2.2.3@aar') {
        transitive = true;
    }
    compile('com.twitter.sdk.android:twitter:1.3.2@aar') {

    }

Replace:

compile 'com.tokbox:opentok-server-sdk:2.3.2'

With:

compile group: 'com.tokbox', name: 'opentok-server-sdk', version: '2.2.0'

and Rebuild. This Should Solve your problem.

Also, add this in your build.gradle file, if you have not already added them.

packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'        
        exclude 'META-INF/ASL2.0'
    }

I hope you have this already in your build.gradle, if not than include it too

        **multiDexEnabled true**

And compile 'com.android.support:multidex:1.0.0' in Dependencies.
