app launches correctly when sending test push notification from firebase console

No response

[fullflash]

if some one can explain what is the reason of this error. if message is receiving on target device that means no problem with configuration also if app launches by firebase console test message but causing this error when sending using firebase admin sdk.

Hi @fullflash, I'm unable to reproduce this issue. Have you tested with other Android devices?

I've having the same issue, from what I can see the background handler works the very first time (on a fresh install). Using Postman I notice the message ID is always the same, so it seems Android/Flutter isn't clearing the message ID or fully receiving it, so as a result when tapping the icon nothing happens (well it launches the app but doesn't fire the on tap logic).

The pay load I'm using is from their docs:

{
"message": {
"token": "e1wAoS4JTh64NNKPG-Rsw3:APA91bEkMLHpt9I_zUSBEnWMyYeOQPE8y8svNDGxReehZyK_Jjk9aUulfuTJymqLy7K6QUJqje2L7ddv0xms6ijoGGDEfcX1IVwdfi0xS9Vm_qCd8aRaSxg",
"notification":{
"title":"Portugal vs. Denmark",
"body":"great match!"
},
"data" : {
"Nick" : "Mario",
"Room" : "PortugalVSDenmark"
}}
}

and the same message ID is always returned. I have tried the specific Android properties too and the click_action etc, to no avail. The FCM console works every time.

the solution was to removing click_action: 'FLUTTER_NOTIFICATION_CLICK' from json payload that you are sending from backend.

 {
        notification: {
            title: pushTitle,
            body: pushBodyMsg,
            image:pushImgUrl
            // click_action: 'FLUTTER_NOTIFICATION_CLICK' //remove this line
        },
        data:pushData,
        tokens:deviceTokensArray
    };
