Decoding a QR code in an Android application?
In Android, Using ZXing we can scan a QR code through phone camera and decode it. But, in my scenario, the QR code image is stored in the phone itself and I need to decode it. Is there anyway to decode a QR image in this manner? You can use ZXing code for this. Check out DecodeHandler.java . You can simply use the Mobile Vision API for decoding a QR Code from Image.It is very accurate and can detect more than one Qr code over image. You have to include the following library inorder to use Mobile Vision API : compile 'com.google.android.gms:play-services-vision:9.6.1' BarcodeDetector detector =
