How can I implement a listener in Java for my Android foreground service that can detect barcode scanning event and save a resulting barcode to a text file, or display a message when barcode scanned with the barcode.
I already created a foreground service. Is it even possible to have a foreground service with a listener which listens to events when other app (warehouse app) scans a barcode? Our company only needs to additionally to save a barcode with time of scanning to a database.
