Android Question fm_MessageArrived is not raised if an app is in background

[b4auser1]

How to resolve this issue ?

 

[An Schi]

Do you send the push from firebase console or via http request of a b4j/a app.
The console is known to cause such issues and it is recomnended to use b4j.

I use firebase console now. I will try to send message programmatically.

Firebase console is for testing. Never trust it. Use b4j instead or b4a as well.

When I sent message programmatically app fm_MessageArrived was raised in background.

I have found the explanation why fm_MessageArrived is NOT raised in background when it is initated from Firebase console.
Firebase console sends always Display message (more details below).

There are two types of messages in FCM (Firebase Cloud Messaging):
Display Messages: These messages trigger the onMessageReceived() callback only when your app is in foreground
Data Messages: Theses messages trigger the onMessageReceived() callback even if your app is in foreground/background/killed
Firebase team have not developed a UI to send data-messages to your devices, yet.

NOTE: Be sure you're not adding JSON key notification

Display Messages

    "notification": {
        "title" : "title text",
        "body" : "body text"
     },

Data Messages

    "data": {
        "my_custom_key" : "my_custom_value",
        "other_key" : true
     },
