Android Question How to read contents from another app's screen using Accessibility service?

[Inman]

I have seen quite a few apps do this. There is Universal Copy that allows you to copy any text from the currently visible screen. There are apps such as MySmartPrice that overlay a "bubble button" on top of Amazon app, reads the product name and searches for lower priced listings of the same product at other sites.

I understand this is done using Accessibility service on Android. Here are a couple of links discussing this:

Can we do this in B4A?

Thanks Don. I did see the first link but NotificationListener can only read notifications and not text from another app's Activity. The second link was promising but sadly it didn't reach anywhere.

Any leads?
