Question

Android

I'm developing an application for my thesis, writing on Rad Studio 10.2 Tokyo. I need barcode recognition in the application, for this I want to use a third-party application, the application https://play.google.com/store/apps/details?id=com.... has support for what would call it then for barcode recognition, I met this in the Electrum application. So: how can I make it so that when the button is pressed, this application is called and after recognition the text that it recognized is returned?
