I need to implement a QR code reader in my activity, ie NO REDIRECT. Using ZXing will not solve my problem.
To get an idea, check out whatsApp in the WhatsApp Web function: There is an activity, with text above, and so, and then just below a square, with the camera already active, just waiting for you to point the phone to QrCode.
That's what I need. Develop a QR code reader within my own activity. Without having to call another API, redirect, push a button to start, none of it.
Important detail before anyone responds: Using ZXing will NOT SOLVE MY PROBLEM unless you have modified the code so that I can use it in MY OWN ACTIVITY, ok:)
Can someone please tell me a tutorial or give me a tip? I use Android Studio.
