Android Question Ruining in background

Use a service in b4a don't do it in Starter I think. You can tell the service to be sticky or set to foreground.

The B4i version receives the messages even if the application is running in the background and no messages are lost

There is no such thing. The OS will kill your app after a few minutes.

You should use a foreground service with a partial lock.

Hi Erel,

I am using the foreground services as below code, but the application loses messages during it is in the background.


Private Sub client_MessageArrived (Topic As String, Payload() As Byte)


If IsPaused(Chat)=True Then

snotif.Initialize
snotif.Icon = "logo.png"

snotif.Sound = False
snotif.Vibrate=False
snotif.OnGoingEvent=False
snotif.Notify(1)
Service.StartForeground(1,snotif)
snotif.AutoCancel = True
.....


....

The whole point of push notifications is that you don't need to run your app for the message to arrive. The app will start automatically (the relevant service).

If it doesn't work for you then you haven't configured it correctly.
