Google Play Services official plugin from Google missing manifest element

I've tried using https://github.com/playgameservices/play-games-plugin-for-unity to implement in my game, but after doing all the steps and trying it out I get the following error in my logs:

I/Unity (18399): AndroidJavaException: java.lang.IllegalStateException: A required meta-data tag in your app's AndroidManifest.xml does not exist. You must have the following declaration within the element: @integer/google_play_services_version" />

Anyone else experience this issue?

 

I've been trying to deal with this issue as well. I see several answer explaining that you should add the following code to your AndroidManifest.xml

Code (csharp):

1. <application
2. <meta-data
3.     android:name="com.google.android.gms.version"
4.     android:value="@integer/google_play_services_version" />
5. </application>

When I do this, I no longer get the error you also mentioned. However the game seems to just crash as soon as I attempt to authenticate the user. Anybody having the same problem?

Edit: Found another plugin that simply worked after 3 simple steps. https://github.com/faizann/UnityGPGPlugin
