Hi,

B4X: 
Sub Process_Globals
    Private listener As NotificationListener
    

Sub Service_Create
    listener.Initialize("listener")
    
Sub Service_Start (StartingIntent As Intent)
    If listener.HandleIntent(StartingIntent) Then
        Return
    End If

I don't know what is wrong and my app crash when this happens

I think that I find out what is wrong

B4X: 
Sub Listener_NotificationPosted (SBN As StatusBarNotification)

    Dim jno As JavaObject = SBN.Notification
    Dim extras As JavaObject = jno.GetField("extras")

        If OsVersion.SdkVersion >= 19 Then
            If SBN.IsInitialized Then
                extras.RunMethod("size", Null)

I was trying to get SBN.Notification before check if SBN was initialized, correct?
