I receive push notifications on ios but not on Android

Question

I need help with notifications on a project of xamarin.forms on the android platform.

The OnTokenRefresh method works well. I create the token correctly and send it to my server, but the problem is that it never enters the OnMessageReceived method when I send a push. In IOS everything is working correctly.

My manifest > receiver =>

<?xml version="1.0" encoding="utf-8"?><manifest

My FirebaseInstanceIdService implementation =>

[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);
        Helper.Settings.PlatformSNS = refreshedToken;
    }
}

My FirebaseMessagingService implementation =>

[Service]
[IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]
public class MyFirebaseMessagingService : FirebaseMessagingService
{
    const string TAG = "MyFirebaseMsgService";
    public override void OnMessageReceived(RemoteMessage message)
    {
        base.OnMessageReceived(message);
        Log.Debug(TAG, "-------------------------------ES UN MENSAJE-------------------------------");
        Log.Debug(TAG, "From: " + message.From);
        Log.Debug(TAG, "Notification Message Body: " + message.GetNotification().Body);
        
    }
}

Solved

The problem was (or I think it is) in the package name. old => com.mycompany.Company. New => com.mycompany.company.

With the new package everything works fine.

So, what is it? The title says Android works. In the question it says Android doesn't work. — Gerald Versluis, Jul 12 '18 at 13:27

I followed that implementation guide. OnTokenFresh works well but not OnMessageReceived — Miguel Angel Muñoz, Jul 13 '18 at 06:37

Try this in your manifest.

  <?xml version="1.0" encoding="utf-8"?><manifest

          <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
          <category android:name="yourAplicationName" />
        </intent-filter>
      </receiver>
    <provider android:name="android.support.v4.content.FileProvider"

        <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
        <category android:name="${applicationId}" />
      </intent-filter>
    </receiver>

I tried but he didn't compile me. He shows me an error and I don't know why he does it. https://imgur.com/a/zJFuTIQ . I've changed companyname to the name of my package but it's still the same. — Miguel Angel Muñoz, Jul 13 '18 at 13:33
you need to change "${applicationId}" for your project name. — Rafa Vieira, Jul 13 '18 at 14:24
I've already changed it but it's still the same. What is the ApplicationId exactly? The package? my package is not com.companyname.OtherName but com.otherName.OtherName. can that be the problem? — Miguel Angel Muñoz, Jul 16 '18 at 07:00
Yes, you need have the same package name, in application and Firebase. — Rafa Vieira, Jul 16 '18 at 08:18
Can you update your manifest on your question. I'll try to repair the code. — Rafa Vieira, Jul 16 '18 at 08:49
I've updated the manifest. I tried all the possibilities I could think of but it didn't work. I really appreciate your help. — Miguel Angel Muñoz, Jul 16 '18 at 09:30
What a frustration I have. I will have some small line wrong but I can't find it. Would you give me your github user? I have prepared an example that should work with the same Package but still the same, thank you very much Rafa. — Miguel Angel Muñoz, Jul 16 '18 at 13:21
