BarcodeDetector

Recognizes barcodes (in a variety of 1D and 2D formats) in a supplied Frame.

Build new BarcodeDetector instances using BarcodeDetector.Builder. By default, BarcodeDetector searches for barcodes in every supported format. For the best performance it is highly recommended that you specify a narrower set of barcode formats to detect. For example, to create a detector that recognizes only Data Matrix and QR codes:

BarcodeDetector detector = new BarcodeDetector.Builder(context)
     .setBarcodeFormats(Barcode.DATA_MATRIX | Barcode.QR_CODE)
     .build();
 

Recognition results are returned by detect(Frame) as Barcode instances.

Adding the vision functionality dependency to your project's AndroidManifest.xml will indicate to the installer that it should download the dependency on application install.
