Android Question Clicking the notification only opens the app when the app has been manually opened at least once.

    If StartingIntent.IsInitialized Then fm.HandleIntent(StartingIntent)
    Sleep(0) ' i Testet whitout this line
    Service.StopAutomaticForeground 'remove if not using B4A v8+.
End Sub

This code is not relevant. Where is the code that creates the notification?

How are you testing it? Are you explicitly killing the app?

 

[Alankoba]

Firebase creates a notification automatically, even without any code in fm_MessageArrived. When the app is open (showing on screen) then the fm_MessageArrived event is fired, and a msgBox is displayed.

Sub fm_MessageArrived (Message As RemoteMessage)
    Log("Message arrived")
    Log($"Message data: ${Message.GetData}"$)
    CallSub3(Main, "msgPush", Message.GetData.Get("title"), Message.GetData.Get("body"))
End Sub

After 45 seconds of clicking (approximate time) the app opens correctly. Can this be something with the foreground?

CallSub3(Main, "msgPush", Message.GetData.Get("title"), Message.GetData.Get("body"))

You need to first check if the Activity is active before using CallSub3. A better way would be to use CallSubDelayed3. See https://www.b4x.com/android/forum/t...teract-between-activities-and-services.18691/

No it doesn't. You are probably seeing the automatic foreground notification.

The only way to start an activity from a service, while the app is in the background, is by calling StartActivity.
