Unable to merge android manifests

C:\Users\abdullah\Documents\Unity Projects\The Cartel\Temp\StagingArea\AndroidManifest-main.xml:32:67-97 Error:
Attribute meta-data#com.google.android.gms.games.APP_ID@value value=(@String/app_id) from AndroidManifest-main.xml:32:67-97
is also present at AndroidManifest.xml:19:13-46 value=(\u003148048280396).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest-main.xml:32:5-100 to override.

UnityEngine.GUIUtilityrocessEvent(Int32, IntPtr)

 

I get these types of errors frequently with Google Play Games Services. What is probably happening is one plugin or another (perhaps GPGS itself) has a manifest file that is conflicting with another. I'd start by comparing all the AndroidManifest files and figure out whats conflicting (hard to say for sure what it is from these vague errors). Make sure android min versions match, for starters.

Similar problem here:

Search all of the AndroidManifest.xml files in your project for this element: com.google.android.gms.games.APP_ID
There can only be one of these (especially since it is probably defined more than once, with different values).
