Android Question Problem with FirebaseMessaging

[pacpinto]

Hi,

I'm having trouble getting Firebase notifications working. On iOS I was able to do it without much issues, but on Android I'm at a loss.
I followed the tutorial at https://www.b4x.com/android/forum/t...-messages-firebase-cloud-messaging-fcm.67716/ but when I try to send a notification, my app crashes with these messages written to the log:

FirebaseMessaging not found.
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String java.lang.Class.getName()' on a null object reference
    at android.content.ComponentName.<init>(ComponentName.java:132)

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:980)

The app compiles and runs without any issue except when a notification is sent.
Any help would be greatly appreciated.

Thanks!

Have you added a service named FirebaseMessaging?

Hi Erel,

Yes I did:

Sub Process_Globals
    'Firebase
    Private fm As FirebaseMessaging
End Sub

and then

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

I went through the tutorial several times already, updated the android SDK, and installed the latest version of B4A...

Thank you

Yes I did

and this code is in a service named FirebaseMessaging? It is mandatory that the service has THIS name!

Oooops! Sorry, this was indeed my mistake. Such a basic thing... all solved now.
Thank you for your help.
