Missing api_key/current key with Google Services 3.0.0

Question

Since I upgraded the project with the latest version of google services and libraries (9.0.0), I have this strange issue :

Grade console :

Answer 1

First in your JSON file

Replace

"api_key": []

with

"api_key": [{ "current_key": "" }]

Then the gradle build will be successful but when you run your application you may get errors like the following..

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/LICENSE
    File1: C:\Users\bucky\.gradle\caches\modules-2\files-2.1\com.fasterxml.jackson.core\jackson-core\2.2.2\d20be6a5ffffd6f8cfd36ebf6dea329873a1c41f1b\jackson-core-2.2.2.jar

    File3: C:\Users\bucky\.gradle\caches\modules-2\files-2.1\com.fasterxml.jackson.core\jackson-annotations\2.2.2\285cb9c666f0f0f3dd8a1be04e1f457eb7b15113\jackson-annotations-2.2.2.jar

To fix this issue you can add the following to your app.gradle file.. It worked for me.

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'
    }

Edit: It showed me some error later while building the apk file. So I had to download the json file again. After 2 trial I got the json file with a valid api key.
