Failed to sign in. Please check your network connection and try again

Question

I am trying to make simple game with Google Play Games Services, but I failed to sign in to Google Play Games.

I get this error:

Failed to sign in. Please check your network connection and try again.

I have MainActivity, and three fragmenets (MainFragment, GameFragment and ResultFragment).

MainFragment is fragment for main menu, where use have button to click to start the game.

Authorization?

I have linked and authorized my game with SHA-1 in Google Play Developer Console.

As I use Android Studio my package name looks something like: aplikacijezaandroid.thebuttonchallenge, and I added two app version in linked apps on Google Play Developer Console.

So I have com.aplikacijezaandroid.thebuttonchallenge, and aplikacijezaandorid.thebuttonchallenge

App ID?

I added app id, and leaderboard id into strings.xml and I added meta tag to Android Manifest.

I have added Internet permission in AndroidManifest.xml

Testing?

I test and debug app from Android Studio with physical device and ofc there is my own gmail added as test user in Google Play Developer Console.

Here is my AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="aplikacijezaandroid.thebuttonchallenge" >

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
   <meta-data android:name="com.google.android.gms.games.APP_ID" android:value="@string/app_id"/>
   <meta-data android:name="com.google.android.gms.version" 

  android:value="@integer/google_play_services_version"/>
  </application>

Here is MainActivity class:

Answer 1

I have solved this problem, so I will post the answer.

I have moved app id and leaderboard id from strings.xml to ids.xml in values folder.

I have deleted all client ids and add again client ids for debug keystore and release keystore.

Answer 2

If you haven't published your app/game: After you done every usual step, make sure you test your app/game with a device has only the test account/s. I checked every step a few times and ended with this weird problem. Lastly i tested my app with a device has only test account i added on Developer Console. It worked. Hope, this helps someone else.

Answer 3

In my case the problem was one of gmail accounts (out of two) was not added to the testers accounts at the play store and was the default account for my device.

I removed the account to make the other account (testers account at playstore) default and added it back again, and it started working
