Integration with Google Play Game Services fails because "Play Games callback indicates connection failure."

I have included Google Game Services in my NDK game using minimalist code example.

When launching the application, authentication fails with an error in the logs:

V/GamesNativeSDK( 7212): Play Games callback indicates connection failure.
I/GamesNativeSDK( 7212): UI interaction required to connect to Google Play.
I/TeapotNativeActivity( 7212): Sign in finished with a result of -3
I/biplane ( 7212): OnAuthActionFinished
I/biplane ( 7212): You are not logged in!
I/TeapotNativeActivity( 7212): Fetching all blocking
I/TeapotNativeActivity( 7212): --------------------------------------------------------------
I/TeapotNativeActivity( 7212): Fetching all nonblocking
I/TeapotNativeActivity( 7212): --------------------------------------------------------------
I/TeapotNativeActivity( 7212): Achievement response status: -3

      

        
        
        
      

    

I followed all the steps outlined in the online documentation, including:

• Created a game service in the Google Play developer console and linked the two apps.
• Associated app with debug key
• Linker app with Release key
• Took app id from linked apps (same id for both linked apps) and put it in res / values ​​/ ids.xml
• Created leaderboards and put their ids in res / values ​​/game-ids.xml
• Added a tag for my AndroidManifest.xml with name = "com.google.android.gms.games.APP_ID" and value = "@ string / app_id"
• The latest Game Services app update has been downloaded.
• Listed myself as a test user.

I'm not sure which message is the original error and which is the symptom. "Connection error" or "User interface interaction required".

Note that in the Developer Console, two related applications are listed as Ready to Publish.

The source code I am using is a verbatim copy of StateManager.cpp from the C ++ code examples, and in my android_main I also copied the example code snippet:

// gpg-cpp:  Here we create the callback on auth operations
auto callback = [&](gpg::AuthOperation op, gpg::AuthStatus status) {
    LOGI("OnAuthActionFinished");
    if (IsSuccess(status)) {
        LOGI("You are logged in!");
    } else {
        LOGI("You are not logged in!");
    }
    //engine.animating = 1;
};

if (state->savedState != NULL)
{
    // We are starting with a previous saved state; restore from it.
    engine.state = *(struct saved_state*)state->savedState;
    LOGI("Restored state");
}
else
{
    LOGI( "No saved state to restore." );
    gpg::AndroidPlatformConfiguration platform_configuration;
    platform_configuration.SetActivity(state->activity->clazz);
    // Now, create the game service (see StateManager.cpp) and pass in callback
    StateManager::InitServices(platform_configuration, NULL, callback);
}
