Firebase onMessageReceived not called when app in background

Question

I\'m working with Firebase and testing sending notifications to my app from my server while the app is in the background. The notification is sent successfully, it even appe

Answer 1

The backend I'm working with is using Notification messages and not Data messages. So after reading all the answers I tried to retrieve the extras from the bundle of the intent that comes to the launched activity. But no matter which keys I tried to retrieve from getIntent().getExtras();, the value was always null.

However, I finally found a way to send data using Notification messages and retrieve it from the intent.

The key here is to add the data payload to the Notification message.

Example:

{
    "data": {
        "message": "message_body",
        "title": "message_title"
    },
    "notification": {
        "body": "test body",
        "title": "test title"
    },
    "to": "E4An.."
}

After you do this, you will be able to get your info in this way:

intent.getExtras().getString("title") will be message_title

and intent.getExtras().getString("message") will be message_body
