Google Play游戏Unity SDK无法创建GameServices对象

Question

我无法使用Google Play Unity插件登录，此代码之前正在运行，现在它无效。

PlayGamesPlatform.Activate ();
PlayGamesPlatform.Instance.localUser.Authenticate (success => {
if (success) {
    LoginType = LoginType.Google;
    StartCoroutine( WaitForEmail());

} else {
    Debug.LogError ("Cannot Login with Gmail");
    return;
}
});

我更新了Google Play服务库。

这是Adb logcat输出：

感谢。

Answer 1

根据此Github，消息：InvalidOperationException: There was an error creating a GameServices object. Check for log errors from GamesNativeSDK通常表示Android SDK太旧了。您应该更新Google Play服务，Google Repository，Android支持库和Android支持存储库组件。

问题的另一个原因是版本8.4.0与Play服务API版本9.8.0不兼容

以下是Google Play services API的更新版本列表。

这对我有帮助。

可以确认此方法有效

body {
    scroll-snap-type:y mandatory;
}

body.fix {
    display:inline-block;
    width:100%;
}

<script>
    document.body.classList.add('fix');
    setTimeout(function() { document.body.classList.remove('fix'); }, 0);
</script>

是的，更正后，我收到了错误“身份验证失败” 。

但这是SHA-1的问题。我决定这样做的时间：

open template-AndroidManifest.txt
"\ APP_ID" to "\u003__APP_ID__"
setup GPGS from Unity (press Window/Google Play Services/Setup)

然后在应用程序设置的https://console.developers.google.com/apis/credentials中放入正确的SHA-1。
