android-ndk - Google Play 游戏服务集成失败， "Play Games callback indicates connection failure."

Question

我使用极简代码示例将 Google 游戏服务与我的 NDK 游戏集成。

启动应用程序时，身份验证失败并在日志中显示:

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

我已经执行了在线文档中列出的所有步骤，包括:

在 Google Play Developer Console 中创建了一个游戏服务并链接了两个应用程序。

带有调试 key 的链接应用程序

带有释放键的链接器应用程序

从链接的应用程序中获取应用程序 ID(两个链接的应用程序的 ID 相同)并将其放入 res/values/ids.xml

创建排行榜，并将其 ID 放在 res/values/game-ids.xml

使用 name="com.google.android.gms.games.APP_ID"和 value="@string/app_id"在我的 AndroidManifest.xml 中添加标签

下载了游戏服务应用程序的最新更新。

将自己列为测试用户。

我不确定哪个消息是原始错误，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被列为“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);
}

所以，事实证明这种行为是为了:
如果您以前从未登录过，自动登录(在服务启动时)应该会失败。

您需要先进行用户发起的登录，使用:

game_services_->StartAuthorizationUI();

...在随后的自动登录成功之前。

另请注意，控制台上有很多错误，它们似乎不会干扰 google play 游戏服务的正常运行。

最后一个注意事项:奇怪的是，当我尝试在没有网络连接的情况下登录时，我还看到了“需要用户交互”错误。
