Google Play游戏服务集成失败,"Play游戏回调表示连接失败".

Question

我使用极简主义代码示例将Google游戏服务与我的NDK游戏集成在一起.

启动应用程序时,身份验证在日志中失败:

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

我已执行在线文档中列出的所有步骤,包括:

• 在Google Play开发者控制台中创建了一个游戏服务,并链接了两个应用.
• 使用Debug键链接应用程序
• 链接器应用程序与释放键
• 从链接的应用程序(两个链接的应用程序的相同ID)中获取app-id并将其放在res/values/ids.xml中
• 创建排行榜,并将其ID放在res/values/game-ids.xml中
• 添加了标签到我的AndroidManifest.xml,名称="com.google.android.gms.games.APP_ID"和value ="@ string/app_id"
• 下载最新的Game Services应用程序更新.
• 将自己列为测试用户.

我不确定哪条消息是原始错误,哪个是症状."连接失败"或"需要UI交互".

请注意,在开发者控制台中,两个链接的应用程序列为"准备发布".

我使用的源代码是来自c ++代码示例的StateManager.cpp的逐字副本,在我的android_main中我也复制了示例代码片段:

// 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);
}

因此,事实证明这种行为是有意的:如果您之前从未登录过,则自动登录(在服务启动时)应该会失败.

您需要首先执行用户启动的登录,其中包括:

game_services_->StartAuthorizationUI();

...之后的自动登录将成功.

另请注意,控制台上存在很多错误,这似乎不会影响Google Play游戏服务的正常运行.

最后一点:奇怪的是,我在尝试登录而没有网络连接时也看到了"需要用户交互"错误.
