Android Question Anyone have a working example of how to collect token and use firebase push messages?

You need to somehow map the tokens or unique topics to the users. The common way to implement it is with a server that received the user's token and some other identifier.

I use this sub


In the FirebaseMessaging module receiver, to get a unique token from users and store it in my online database the rest is done in the host by PHP.

If you do not want to do this in receiver you can create a sub in one of your pages like


And change the Sub fm_TokenRefresh (Token As String), so can be used everywhere like this:

The simplest way I implemented in my apps is to use the login information of the User. Example if the user registers with phone number or email, it means you already have these information on your database online.

So when the user login to your app, and it is successful, you just use his phone number or email or user id and subscribe that to your topic.

B4X:

Public Sub SubscribeToTopics
    fm.SubscribeToTopic("general") 'you can subscribe to more topics
    Sleep(0)
    fm.SubscribeToTopic("USERS-INFO-EXAMPLE-PHONE-NUMBER")
End Sub

sounds like a security hole if you use the email or phone number for this. It is safer to use a GUID and store it on the device and an online database in case the app is uninstalled and reinstalled later.
