Android Question Keeping the foreground service alive

[Silkowner]

I have a program and it needs to always be running in the foreground. Do you think the following code is sufficient?

#Region  Service Attributes
    #StartAtBoot: True
    #ExcludeFromLibrary: True
    #StartCommandReturnValue: android.app.Service.START_STICKY
#End Region

Sub Process_Globals
    Private n As Notification
    Dim awak As PhoneWakeState
    Dim pd As PersianDeviceInfo
    Private channelId As String = "ServiceChannel"
    Dim phone As Phone
    Public IsRunning As Boolean = False
    Private snotif As PhoneEvents
End Sub

Sub Service_Create
    snotif.Initialize("ScreenEvents")
    
    CreateNotificationChannel
    Dim n As Notification
    n.Initialize2(n.IMPORTANCE_LOW)
    n.Icon = "icon3"
    n.Sound = False
    n.Vibrate = False
    n.Light = False
    n.Insistent = False
    n.AutoCancel = False
    n.OnGoingEvent = True
    n.SetInfo("بروزرسانی در دسترس است", "", "")
    
    Service.StartForeground(1, n)
    
    awak.PartialLock
    awak.KeepAlive(False)
    IsRunning = True
    CallSubDelayed(FirebaseMessaging, "SubscribeToTopics")

End Sub

Sub CreateNotificationChannel
    Dim importance As Int = 2
    pd.initialize("")
    If phone.SdkVersion >= 26 Then
        Try
            Dim channel As JavaObject
            channel.InitializeNewInstance("android.app.NotificationChannel", Array(channelId, "Service Channel", importance))
            channel.RunMethod("enableLights", Array(False))
            channel.RunMethod("enableVibration", Array(False))
            
            Dim manager As JavaObject
            manager.InitializeContext
            manager = manager.RunMethod("getSystemService", Array("notification"))
            manager.RunMethod("createNotificationChannel", Array(channel))
        Catch
            Log("Error creating notification channel: " & LastException)
        End Try
    End If
End Sub

Sub Service_Start (StartingIntent As Intent) As Int
    Try   
        CreateNotificationChannel
        Dim n As Notification
        n.Initialize2(n.IMPORTANCE_LOW)
        n.Icon = "icon3"
        n.Sound = False
        n.Vibrate = False
        n.Light = False
        n.Insistent = False
        n.AutoCancel = False
        n.OnGoingEvent = True
        n.SetInfo("بروزرسانی در دسترس است", "", "")
        Service.StartForeground(1, n)
        IsRunning = True
        CallSubDelayed(FirebaseMessaging, "SubscribeToTopics")
    Catch
        Log("Error in Service_Start: " & LastException)
    End Try

    Return 1
End Sub



Sub Service_TaskRemoved
    IsRunning = False
    StartServiceAt(RestartService, DateTime.Now + 1000, False)
End Sub



Sub Service_Destroy
    Try
        awak.ReleasePartialLock
    Catch
        Log("kir to akuma(shirin)")
    End Try
    
    IsRunning = False
    
    StartServiceAt(RestartService, DateTime.Now + 1000, False)
End Sub


Sub ScreenEvents_ScreenOn (Intent As Intent)
    Try
        If IsRunning = False Then
            StartServiceAt(RestartService, DateTime.Now + 1000, False)
        End If
    Catch
        Log("fack you sector")
    End Try
End Sub

There are many mistakes in this code. Remove the START_STICKY.

Use NB6 or the built-in notification object.
Set Service.AutomaticForegroundMode to NEVER.
