Notifications and PushNotifications do not work :(

I saw there is a method " onPushNotificationEvent" but is never called, same for normal notifications.

Is this feature (notifications) not implemented yet?

Btw, awesome project, I like how you structured it :D and it worsk very good, just the issue with the notifications.

EDIT:
I get the next error from the notification builder when I send a message :

E/FcmNotificationBuilder: onResponse: {"multicast_id":8285779204958253584,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MissingRegistration"}]}

MissingRegistration.... what could it mean?
EDIT2:
The first edit was my fault, passed an empty string token as parameter when I start ChatActivity.

Now I pass the correct string token of the user I want to recive the notification. This token, transformed to String looks like com.google.android.gms.tasks.zzh@4221a2f8 so I pass as parameter something like this.

But I get again an error:

E/FcmNotificationBuilder: onResponse: {"multicast_id":5901028783144837003,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}

I have no idea why...

EDIT3:
I have tryed to store the tokens in my personal database, but it looks like this token change every time I call getToken(true/false).
Anyway, it didn't make work the notifications.

Thank you for your time.

EDIT4:
I finaly get how works the registration tokens. Actualy I made work the push notifications with FCM

Unable to open the tutorial link and also the app in Android studio

Hey,
I'm unable to open the app in AS it says some files are missing from the directory. May I know how to build the directory and the DB structure?
Can you provide me any tutorial kind of reference for the same?

app crashes at login

this similar to a previously created and "closed" issue without provision of any actual solution: Login and Registrations are happening and are also being reflected in the Console. But the issue is that after the login when app goes to the screen where it will display the users available, there the app is getting crashed.

only one device can access DB

If any user tries to send a message there was nothing and if I sign on my device with this user this user can send or receive messages.

Chat notifications aren't being displayed!!

Hello,
The chat notifications for new message in the status bar when the app is in the background isn't being displayed. May I know what should be done for this?

FirebaseMessagingService Never Called either app in foreground or background, No notification received for messages sent when app closed

The FirebaseMessaging service is not working and onMessageReceived is never called regardless of app in background or foreground. Due to this the notification is also not working. Tried putting log for data received in onMessageReceived, but no logs came, which indicated the service not working. Any idea how to solve this?

Why using EventBus when Realtime database is used

If we are using firebase realtime database it will automatically update the new message in onDataChanged() method if the chatActivity is open, then why the need of eventBus there to pass that a new message came

App is force closing!!

Hey, I followed your instructions from your updated Readme file. Login and Registrations are happening and are also being reflected in the Console. But the issue is that after the login when app goes to the screen where it will display the users available, there the app is getting crashed.
