Hi Van, thanks!
In theory, if it works when the App is opened, it should also work when it’s closed.
Some OEM devices put restrictions on background services causing them to not work properly.
If there is something like the phone’s battery optimization On, turn that off and check for background restrictions put by the device.
See here, how it varies by device:
I don’t have a BTC account now, I have PayPal:
I am now working on a thing that makes calling procedures possible from a background (foreground) service 
Did a few tests yesterday, got them working 
Do upload it on github also please. 
Almost done
Some beta testing and few more tests remaining 
You can count with me to help with the tests. Just send me the aix and tell me what you want me to do and I will be glad to help
Version 4.0 is launched!
A guide that explains the use of procedures for downloading a photo from the internet in the foreground mode.
version 4.0
We create a procedure that will download a photo from the argument.
Currently, if the app closes, events won’t work except for others.
In the event Initialized, we have set the property “Procedures” so that the extension can keep track of the procedures even when the app goes off.
Now we have to create tasks and start them.
We create a component named #Fun here.
It is an inbuilt component.
Then we create a function with a block named “Invoke”.
It is a function that will call our download procedure.
For the values, we have to give it two inputs, the first one will be the procedure name we are calling and the second element are the args in a form of a list, in which there is an image URL.
When the Procedure is invoked completely, an event of name “Processed” will be called, then the function with component “self” and block “stop” is invoked that will stop the service itself.
The last step is to start the service, we define latency and properties accordingly. foreground should be checked to be true for our procedure to work.
Since our program needs internet, we set “requiredNetwork” to “ANY”.
This logic can be applied to all components and inbuilt blocks (maths, texts…).
Foreground mode needs a notification to stay live. To configure the notification accordingly use the ConfigureForeground block.

Make sure to change the Image URL.
You just have to type that, its an inbuilt component in extension. 
No, you have to give it a list of names.
@Xoma, where do these elements come from in “CreateFunction”???:
“end task”
“self”
“exit”
maybe example from standard components from Kodular?
Those are inbuilt. You don’t have to do anything.
to be honest, I didn’t understand at all where the “self” component and the “exit” block came from (((
we don 't understand your thoughts ) We need simple examples.
What do you mean? Just they are inbuilt, pre created things (in a simple way). You just mention and use them.
ok.
math function?
How use the #Fun component for “math” operation?
Please understand how it works before asking it. You apply the same logic of the procedure.
in examle “Blocky” where is the creation “end task-self-exit”?
or can procedures be called only once?
