如何知道是否通过Android上的通知启动了应用/游戏？

Question

I'm making a game in Unity for Android. I have implemented a notification system. Notifications show and clicking on them opens the game. The thing I'm stuck on is how to know if the game/app is launched by tapping the notification?

Here is the java code for the notification plugin I'm using https://github.com/GoShikhar/unity-android-notifications/blob/master/PluginSrc/app/src/main/java/net/agasper/unitynotification/UnityNotificationManager.java

This is my manifest https://github.com/GoShikhar/unity-android-notifications/blob/master/UnityProject/Assets/Plugins/Android/AndroidManifest.xml

In my unity start scene I use this to check for intent messages.

void Start(){
 AndroidJavaClass unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
 var activityObject = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity");
 AndroidJavaObject intent = activityObject.Call<AndroidJavaObject>("getIntent");
 int NotificationID = intent.Call<int>("getIntExtra", "id", -1);
 print("NOTIFDICATION ID " + NotificationID);
 bool hasExtra = intent.Call<bool>("hasExtra", "arguments");
 string arguments = null;
 if (hasExtra)
 {
    AndroidJavaObject extras = intent.Call<AndroidJavaObject>("getExtras");
    arguments = extras.Call<string>("getString", "title");
    print("title : " + arguments);
    arguments = extras.Call<string>("getString", "message");
    print("message: " + arguments);
 }

 if (arguments != null)
 {
        print("App opened via notification");
 }
}

This not working. The default notification ID is being printed ie -1. Also title and message are null. Even though the notification has the title and message parameter.

I have seen lots of examples for Android Studio but not for Unity. So any help will be appreciated.

Thanks in advance.

Do you mean deep linking? Perhaps this Github project would be helpful: https://github.com/TROPHiT/UnityDeeplinks .
