Android Question Trying out Firebase Cloud Messaging

microbox · Sep 12, 2016

Hi, I'm trying to learn how the Firebase cloud messaging works...but not really sure what to do next.
So far this is what done so far.

1. Open Android SDK Manager and install the latest versions of:

- Android Support Repository
- Google Repository

2. Register with Firebase and create a new project: https://firebase.google.com/docs/
Make sure that the package name matches your app's package name.

3. Download google-services.json and put it in the projects folder (folder of the b4a file).

4. Add the manifest snippets to the manifest editor based on the services that you need.

Below is what I have in my manifest file.

B4X:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: https://www.b4x.com/forum/showthread.php?p=78136

    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")

I hope someone can tell What will be next step(s)?

Kind regards,

You also need Google Play Services.

Hi Pendrush, Thanks..just updated my manifest and added the Google Play Services.

Maybe my next question is how can I use it in my app?

Thanks again for the time,
Joe

Follow the tutorial. In your reciever app you want to add the firebase service and maybe a notification to show it.
Then you need a sender. You can send the push from the firebase console, but the recommended way is to use an API call which you can do with a b4j or b4a app.

Hi An Schi... I'm really new to this

is the code below what I need for testing?

B4X:

Sub Process_Globals
   Private fm As FirebaseMessaging
End Sub

Sub Service_Create
   fm.Initialize("fm")
End Sub

Public Sub SubscribeToTopics
   fm.SubscribeToTopic("general") 'you can subscribe to more topics
End Sub

Sub Service_Start (StartingIntent As Intent)
   If fm.HandleIntent(StartingIntent) Then Return
End Sub

Sub fm_MessageArrived (Message As RemoteMessage)
   Log("Message arrived")
   Log($"Message data: ${Message.GetData}"$)
   Dim n As Notification
   n.Initialize
   n.Icon = "icon"
   n.SetInfo(Message.GetData.Get("title"), Message.GetData.Get("body"), Main)
   n.Notify(1)
End Sub

Sub Service_Destroy

End Sub

Thanks,
Joe

Yes. That's the firebase service you need in your reciever app. Add a new service module to your project and copy & paste this into it.
For the first tests you can use the firebase console to push.

I think I'm still lacking something. After compiling and sending test message from firebase console, I did not receive any yet.

An Schi · Sep 12, 2016

Follow the tutorial!
It says:

2. Add a Service named FirebaseMessaging to your app (must be this name):

You didn't name your service like this.

Hey An Schi...thanks

I think I'm receiving the notification. But I have another question if you don't mind.

How can I see the content message?

microbox · Sep 12, 2016

I finally got it...at first it was showing null...but after several attempt messages arrived. Thanks Pendrush and An Schi

- Android Support Repository
- Google Repository

Update the repos to the newest release!

microbox · Sep 13, 2016

Thanks DonManfred I updated Google Repository.

I tried my demo application today but no messages arrived

I use firebase console. Any idea what I'm missing?

You should use the B4J code to send requests: https://www.b4x.com/android/forum/t...s-firebase-cloud-messaging-fcm.67716/#content

microbox · Sep 13, 2016

Hi Erel, I placed my API Key but I'm not receiving any message. Probably I'm still missing something in the B4J code.
Debug output:

B4X:

Waiting for debugger to connect...
Program started.
[jobname=fcm, success=true, username=
, password=, errormessage=, target=class b4j.example.main
, taskid=1, req=anywheresoftware.b4h.okhttp.OkHttpClientWrapper$OkHttpRequest@70f11, tag=java.lang.Object@16e523d
, httputils2service=null]
{"message_id":7907454354097248626}
Program terminated (StartMessageLoop was not called).

Erel · Sep 13, 2016

Make sure to follow the exact steps from the tutorial: https://www.b4x.com/android/forum/t...s-firebase-cloud-messaging-fcm.67716/#content

It will work once everything is configured correctly.

microbox · Sep 23, 2016

Just want to ask when to use "Web API Key" and "Server key"?

Erel · Sep 24, 2016

As written in the tutorial you need to use the server key. There is also a screenshot.
