i have no idea what that means. let's just assume we can dismiss image 2 as irrelevant.
if you're going to use a qr code to launch an app, you need an app to scan the code and to handle an intent to launch an app. it looks like you're relying on your default camera app to handle that. that could be a problem. first, device manufacturers are responsible for their own default camera app. that would include its various features.
in my case (i use google pixel devices), the default camera app has a setting to allow qr codes with a url to launch the default action for such qr codes. that action being to launch the default web browser. to repeat, in the case of pixel devices, the user has to activate that behavior in the app's settings. i would assume the case is similar for your device. the bad news is that your custom url will probably not be recognized as something it can handle. this means you will need an app which can scan and decode a qr code and then try to launch any app which knows how to respond to the custom url intent filter. you have the second part, but maybe not the first part.
i have both parts, so when i scan your qr code (or the one i generated myself), it launches your app. since the url's in most qr codes are designed to launch web browsers, you need one that can launch any url (or at least try). if you pick a simple qr code scanner from among the many available on the forum, you should be able to modify it to run an intent whose scheme is your custom url:
Dim intent As Intent
intent.Initialize(intent.ACTION_VIEW, "ilogclnt://open")
StartActivity(intent)
qr codes don't automatically do anything. and applications that scan and decode them don't automatically do anything with them. and those that can recognize url's don't necessarily recognize any beyond a list of generally recognized schemes (eg, http(s),ftp,email,geo,sms, ...) if you want to launch your custom url from a qr code, you need to do that yourself.
the applinks reference may not have anything to do with qr codes.
