如何在unity使用Firebase Messaging的功能?

1. 在Unity Assets中create C# script (ex.FBS)
   

2. 在FBS中，寫入下方的code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Firebase.Extensions;

public class FBS : MonoBehaviour
{
    public void Start()
    {
        Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(task => {
            var dependencyStatus = task.Result;
            if (dependencyStatus == Firebase.DependencyStatus.Available) {
                // Create and hold a reference to your FirebaseApp,
                // where app is a Firebase.FirebaseApp property of your application class.
                Firebase.FirebaseApp app = Firebase.FirebaseApp.DefaultInstance;

                // Set a flag here to indicate whether Firebase is ready to use by your app.
    } else {
        UnityEngine.Debug.LogError(System.String.Format(
        "Could not resolve all Firebase dependencies: {0}", dependencyStatus));
        // Firebase Unity SDK is not safe to use here.
    }
    });

    Firebase.Messaging.FirebaseMessaging.TokenReceived += OnTokenReceived;
    Firebase.Messaging.FirebaseMessaging.MessageReceived += OnMessageReceived;

    }

    public void OnTokenReceived(object sender, Firebase.Messaging.TokenReceivedEventArgs token) {
        UnityEngine.Debug.Log("Received Registration Token: " + token.Token);
    }

    public void OnMessageReceived(object sender, Firebase.Messaging.MessageReceivedEventArgs e) {
        UnityEngine.Debug.Log("Received a new message from: " + e.Message.From);
    }

}

3. 按左上角File -> Build setting -> Build (APK檔)
   
4. 開啟Firebase專案，按Messaging
   
5. 按建立第一個廣告活動
   
6. 按firebase通知訊息(只要有安裝APP，都會收到訊息，不用打開APP)
   
7. 寫下要通知的標題和內容
   
8. 在Unity的player setting -> player -> package name，在下方照片位置寫入
   
9. 設定想要傳送訊息的時間
   
10. 按下一步(如果沒有重要事件)
    
11. 設定到期時間以及音效，最後按審查
    
12. 按發佈
    
13. 可以看到訊息正在傳送當中
    
14. 可以看到傳送的次數
    
15. 在手機上收到訊息
    

可能遇到的問題
按發佈之後，手機沒有收到訊息，為甚麼?

1. 網路的問題，可能要等3-5分鐘之後，就會收到了
2. 可能package name寫錯了要回去檢查一下
