1) Set this attribute:
#StartCommandReturnValue: android.app.Service.START_STICKY
see: https://www.b4x.com/android/forum/t...-long-running-background-tasks.27065/#content

2) Start service with:
Service.StartForeground

3) Add Notify

 

[taylorw]

If i don't want notify can do this?

 

[Star-Dust]

Try. But I'm not sure you can not kill unless you put a notify ... even empty

But you can try it

 

[DonManfred]

If i don't want notify can do this?

Then you can not use a Sticky Service.
A Sticky service must show a Notificationicon (as far as i know). The Sticky prevents Android from killing your Service.

 

[taylorw]

Oh i see, thank you Star-Dust and DonManfred.
I will try it.

 

[taylorw]

I already try, but when i clear ram the notify will be close.
This is where i put START_STICKY, is it correct?

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

 

[Star-Dust]

Did you do something like that in the service?

Dim n As Notification
   
Sub Service_Create
  n.Initialize
  n.Icon = "icon"
  n.Vibrate = False
  n.Sound = False
  n.Light = False
  n.OnGoingEvent=True
  n.SetInfo("", "",Main)
  n.Notify(1)
  Service.StartForeground(1, n)
End Sub

 

[taylorw]

Yes, i have do it.

Dim n1 As Notification
            n1.Initialize
            n1.Icon = "icon"
            n1.Vibrate = False
            n1.Sound = False
            n1.Light = False
   
            n1.SetInfo("VegeTrade", "", Me)
            Service.StartForeground(1,n1)

 

[Star-Dust]

It seems all right

 

[taylorw]

Yes i think so, but why it will be close?

 

[Star-Dust]

At the moment I have no answer. In the afternoon I can take a look, unfortunately now I have to go ...

 

[taylorw]

It's okay, thank you Star-Dust.

 

[taylorw]

This is my sample project.

 

[Star-Dust]

But what is the program to clean the ram?
In my devices does not disappear ..

What device do I use and what version of Android?

 

[taylorw]

Sorry about i just saw your reply.
I clear ram not using app to clear.
Like this original clear.

My phone model number is <PLK-L01>, android version 6.0

 

[DonManfred]

This is a task-killer
