Troubleshoot Cordova / Phonegap Dependencies conflict with Android – MOCA Platform

SYMPTOM

You receive the following error message at compile time:

:transformClassesWithDexForDebug
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/internal/zzr;

SOLUTION

MOCA Plugin for Cordova / PhoneGap requires the following dependencies on Android:

Google Play Services (GPSS) - Cloud Messaging (GCM)
GPSS - Location Services
GPSS - Ads
MessagePack

If you are using other plugins within your project, it is common that some of these plugins rely also on GPSS for some functionality. The problem arises when any of these libraries use a different version of GPSS.

MOCA Plugin expects at least GPSS version 8.3. We provide you the plugin with this version in the plugin configuration, so you can have predictable builds in the future.

In order to fix this issue, please use one of the following solutions:

Option A:

Change the mocabuild.gradle file within the plugin folder and change all the versions to the latest one, bear in mind that your other plugins should also use the same version.

Option B:

Create a file called build-extras.gradle in the following folder your_app_name > platforms > android and paste the following code there.

build-extras.gradle

// When set, this function allows code to run at the end of `build.gradle`
ext.postBuildExtras = {
    configurations.all {
    resolutionStrategy {
        //Google Cloud Messaging
        force 'com.google.android.gms:play-services-gcm:+'
        
        //Google Location, Activity Recognition, and Places
        force 'com.google.android.gms:play-services-location:+'

        //Google Mobile Ads
        force 'com.google.android.gms:play-services-ads:+'
    }
  }
}

If there is any other plugin that uses any part of GPSS, you should include it here as well, and remember: All GPSS dependencies must use the same version, otherwise you will get errors at Compile or at RunTime.

Below you will find a list of possible GPSS dependencies
