this is my service_start code
B4X: 
Sub Service_Start (StartingIntent As Intent)
    If StartingIntent.Action = "android.provider.Telephony.SMS_RECEIVED" Then
        Log("sms received")
        Dim p As Phone
        Dim status As Int = p.GetRingerMode
        sms_analize(status)
    else If StartingIntent.Action = "android.intent.action.PHONE_STATE" Then
        Log(StartingIntent.GetExtra("state"))
        Select StartingIntent.GetExtra("state")
            Case "IDLE"
                NativeMe.RunMethod("stop",Null)
                reset_flash_status
            Case "OFFHOOK"
                NativeMe.RunMethod("stop",Null)
                reset_flash_status
            Case "RINGING"
                Dim p As Phone
                Dim status As Int = p.GetRingerMode
                call_analize(status)
        End Select   
    End If
End Sub
