I want my application to recognize barcodes taken by camera. Is it possible using Android SDK?
Something like this: Barcode Scanner
780
Open your Camera app and point it steadily for 2-3 seconds towards the QR Code you want to scan. Whenever scanning is enabled, a notification will appear. If nothing happens, you may have to go to your Settings app and enable QR Code scanning.
It's not built into the SDK, but you can use the Zxing library. It's free, open source, and Apache-licensed.
The 2016 recommendation is to use the Barcode API, which also works offline.
