Google Play Services "Failed to sign in. Please check your network connection and try again"

Question

This question has been asked multiple times, yet no answer have worked for me.

Here's some insight :

• I am using BaseGameUtils

• In my logs I am getting You have wrong OAuth2 related configurations, please check. Detailed error: UNREGISTERED_ON_API_CONSOLE

• In my manifest file I have inside the application item I have <meta-data android:name="com.google.android.gms.games.APP_ID" android:value="@string/app_id"

• I have added my email as a tester account

• The game is a draft on the google console API

• I have added INTERNET AND ACCESS_NETWORK_STATE permissions

• I have generated credentials using keytool on the debug.keystore file and copied to SHA-1 result to credentials in the Google Console API

• I have deleted debug.keystore to regenerate a SHA-1 key as shown here

My manifest file looks like this :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.martenscedric.hexpert"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="15" android:targetSdkVersion="23" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/GdxTheme" >
        <meta-data android:name="com.google.android.gms.games.APP_ID" android:value="@string/app_id" />
        <activity
            android:name="com.martenscedric.hexpert.AndroidLauncher"
            android:label="@string/app_name" 
            android:screenOrientation="landscape"
            android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

The implementation looks like this :

private GameHelper gameHelper;
@Override
protected void onCreate (Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    gameHelper = new GameHelper(this, GameHelper.CLIENT_GAMES);
    gameHelper.enableDebugLog(false);

    GameHelper.GameHelperListener gameHelperListener = new GameHelper.GameHelperListener() {
        @Override
        public void onSignInFailed() {

        }

        @Override
        public void onSignInSucceeded() {

        }
    };

    gameHelper.setup(gameHelperListener);

    AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
    initialize(new Hexpert(this), config);
}


@Override
protected void onStart() {
    super.onStart();
    gameHelper.onStart(this);
}

@Override
protected void onStop() {
    super.onStop();
    gameHelper.onStop();
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    gameHelper.onActivityResult(requestCode, resultCode, data);
}

@Override
public void signIn() {
    try
    {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                gameHelper.beginUserInitiatedSignIn();
            }
        });
    }catch (Exception e)
    {
        e.printStackTrace();
    }
}

@Override
public void signOut() {
    try
    {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                gameHelper.signOut();
            }
        });
    }catch (Exception e)
    {
        e.printStackTrace();
    }
}

Answer 1

Turned out it was a refactoring problem. When I refactored the project's name from A to B, I did change the manifest to com.me.B, but not in Gradle.
