org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':transformDexArchiveWithExternalLibsDexMergerForDebug'

Question

I have exported my Unity project to Android Studio project. I wanted to add Firebase Messaging to my project through Studio, since Firebase Messaging implemented in unity was not working.

So I added the following code to my app/build.gradle which is causing me all these problems.

dependencies {
.
.
.
compile('com.google.firebase:firebase-messaging:11.8.0') {
    exclude module: 'support-v4'
  }
}

buildscript {
.
.
.
dependencies {
   .
   .
   .
   classpath 'com.google.gms:google-services:3.1.1'
}

apply plugin: 'com.google.gms.google-services'

I have added google-services.json file to app directory.

If I comment most of the aar dependencies from build.gradle, the app will build successfully without any errors. But the Firebase analytics which I am using in my project won't work.

While building the app I am getting following errors.

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':transformDexArchiveWithExternalLibsDexMergerForDebug'.

Message{kind=ERROR, text=Program type already present: com.google.android.gms.measurement.AppMeasurementContentProvider, sources=[Unknown source file], tool name=Optional.of(D8)}

I believe this is happening due to duplication of dependencies. I don't have enough knowledge on gradle to find out that particular package and exclude from building. Any help is greatly appreciated. Thanks.

My build.gradle is as given below:

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN
buildscript {

Can you change this and try

android {
  compileSdkVersion 27
  buildToolsVersion '27.0.3'

  defaultConfig {
    targetSdkVersion 27
    applicationId 'applicationId'
    multiDexEnabled true
  }

  lintOptions {
    abortOnError false
  }

  aaptOptions {
    noCompress '.unity3d', '.ress', '.resource', '.obb'
  }


  buildTypes {
    debug {
      jniDebuggable true
    }
    release {
      // Set minifyEnabled to true if you want to run ProGuard on your project
      minifyEnabled false
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt'
    }
  }
}

to

android {
  compileSdkVersion 27
  buildToolsVersion '27.0.3'

  defaultConfig {
    targetSdkVersion 27
    applicationId 'applicationId'
  }

  lintOptions {
    abortOnError false
  }

  aaptOptions {
    noCompress '.unity3d', '.ress', '.resource', '.obb'
  }


  buildTypes {
    debug {
      jniDebuggable true
      multiDexEnabled true
    }
    release {
      // Set minifyEnabled to true if you want to run ProGuard on your project
      multiDexEnabled true
      minifyEnabled false
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt'
    }
  }
}

Then, on the AndroidManifest.xml add this

<application
    android:debuggable="true"
    android:name="android.support.multidex.MultiDexApplication">
...
</application>
