java.exe" exited with code 1

Question

Hi,

I'm trying to use notifications through Firebase, but an error appeared when I created the myfirebaseiidservice class
(java.exe" exited with code 1)

This code and the packages I use

using Android.App;  
using Android.Content;  
using Android.OS;  
using Android.Runtime;  
using Android.Views;  
using Android.Widget;  
using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
  
using System;  
using Android.App;  
using Firebase.Iid;  
using Android.Util;  
  
namespace notifi.Droid.Model  
{  
   
    [Service]  
    [IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]  
    public class MyFirebaseIIDService : FirebaseInstanceIdService  
    {  
        const string TAG = "MyFirebaseIIDService";  
        public override void OnTokenRefresh()  
        {  
            var refreshedToken = FirebaseInstanceId.Instance.Token;  
            Log.Debug(TAG, "Refreshed token: " + refreshedToken);  
            SendRegistrationToServer(refreshedToken);  
        }  
        void SendRegistrationToServer(string token)  
        {  
            // Add custom implementation, as needed.  
        }  
    }  
}

Hello,

You used Xamarin.Firsbase.lid 121.1.0.7, it depends on the android version is 12.
You need to edit [Services] to [Services(Exported = true)] for android 12 or later,

Please notice: firebaseinstanceidservice is deprecated

You could use FirebaseMessagingService.

   public class MyFirebaseIIDService : FirebaseMessagingService  
       {  
     
          public override void OnNewToken(string token)  
           {  
               base.OnNewToken(token);  
           }  

Best Regards,

Leon Lu
