Unable to retrieve application from network while i try to connect with google play games services.

Hello everyone,

I recently developed an android game using Unity 5.5.4p4, now im triying to integrate achivements with google play games plugin made from unity.

I already configured step by step the plugin as explained in the documentation. I also have an closed Alpha version of the game uploaded into my google play console just for testing, signed with the sha1 generated in the keystote from player settings in Unity.

So my problem comes now, when my app runs, it try to connect with google play services using this method:

 public bool GoogleLogin(){
         
         bool resp = false;
 
         Social.localUser.Authenticate((bool success) => {
             resp = success;
         });
 
         return resp;
     }

In runtime, the modal of the connection appears but after a few seconds it closes and i get this two errors into my android device monitor:

 10-15 16:30:21.346: E/GameAgent(10854): Unable to retrieve application xxxxxxxxxxxx from network
 10-15 16:30:21.347: E/GameAgent(10854): Application xxxxxxxxxxxx is not associated with package com.mypackage.name. Check the application ID in your manifest.

I know unity detects other manifest files from other plugins and then merge it to generate a final one that is stored in projectFolder/Temp/StaginArea/AdroidManifest.xml.

Aplication xxxxxxxxxxxx is the ID asociated to my app in the google play console, and it match with the ID that i have in my final manifest in this metadata:

 <meta-data android:name="com.google.android.gms.games.APP_ID" android:value="\ xxxxxxxxxxxx" />

The package name that appears in the manifest is the same package i have asociated in google play console > games services > My game

I attach my manifest file with hidden app ID in case it could be useful:

If anyone could help me I would be very grateful, I have been stuck for several days and it's very frustrating.

Things i already doublecheck:

• I have reinported the plugin from unity

• I deleted the AndroidMAnifest.xml to regenerate it

• I have made sure that the SHA1 key is the same as the google play console key and google API console Key

• I'm testing the alpha version with the correct google account that i previously activated in google play console.

• I create a brand new project in Google play console to configurate all the things again from cero.
