适用于 Unity 的 Facebook Audience Network SDK

Question

我将 Unity Audience Network SDK 5.4.1 包导入统一，任何版本，它给了我这个错误：

Assets\AudienceNetwork\Editor\AudienceNetworkPostprocess.cs(25,23)：错误 CS0234：命名空间“UnityEditor”中不存在类型或命名空间名称“iOS”（您是否缺少程序集引用？）

如果我删除 ios 部分并尝试仅在 android 上工作 - 没有任何效果，我尝试播放奖励场景并收到此错误：

NullReferenceException：对象引用未设置为对象的实例 AudienceNetwork.Utility.AdUtility.IsInitialized ()（在 Assets/AudienceNetwork/Library/AdUtility.cs:50） RewardedVideoAdScene.Awake ()（在 Assets/AudienceNetwork/Scenes/RewardedVideo/RewardedVideoAdScene.cs:21）

有没有办法让它工作？我做错了什么或错过了什么？ 以前的插件有效吗？有任何链接吗？ 谢谢。

Answer 1

在不知道你删除了什么的情况下，第二个问题很难解决......

我们只能说它指的是51这一行

 AndroidJavaObject context = currentActivity.Call<AndroidJavaObject>("getApplicationContext");

如果在 PC 上执行，currentActivity 最有可能是 null，因为之前的行 50

AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");

在这种情况下可能不起作用。

第一个听起来像一个“错误”。

您可以使用#if pre-processors 和UNITY_IOS 作为修补程序，至少可以让编译器错误消失

但不保证这能解决您的所有问题。

Google Ads 有类似的错误并使用了相同的修补程序。

否则您可能需要考虑安装 IOS 构建支持，我猜这也会使错误消失（但如果您只想为 Android 构建，当然会不必要地填充磁盘空间）

Answer 2

解决方案：在 AdUtility.cs 添加：

"#if UNITY_ANDROID && !UNITY_EDITOR" 

internal static bool IsInitialized()
    {
#if UNITY_ANDROID && !UNITY_EDITOR
        AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
