acts as the bridge or the middle man between View
and Model
, so it must be called on the View.
onActivityResult
will be as is on your fragment

.
A presenter typically hosts business logic associated with a particular feature, and the corresponding view handles the Android UI work. The view contains almost no logic; it converts the presenter's commands to UI actions, and listens for user actions, which are then passed to the presenter.

You might be mistaken the onActivityResult
is where the business logic is, it is not. That's why you need to pass it to the presenter
when you get the result so the presenter will process (business logic) it and then give it to your repository that will save it.

On the web I found manual with little to none helpful info, API to control device, and android demo application written in eclipse.
I was able to get API wrapper for Delphi and successfully control device, change parameters, turn on off scanner and etc.

Eclipse android demo project is working fine too, did compile and run it without a problem. Dilemma now is how to receive broadcasted intent in Delphi. I have manifest.xml and mainactivity code from working eclipse demo here...
Manifest:

If you need that another intent starts your intent -
you need to attach a special JAR file to your project.
Here is the manual how to do it (use google translate)
