Perhaps "clients" is not the correct word - "activities", perhaps?
Specifically, I need to create an Android app that uses ZXing or similar to detect QR Codes while a video chat (Google Hangouts API or similar) is happening at the same time. Sometimes there will be a person in front of the Android camera, but most of the time the app will be scanning for QR codes that pass by.
Alternatively, I could use Google Hangouts and a custom ZXing app running at the same time. Is that possible?
I'm a novice on Android, so thanks in advance!
