Public Methods

public BarcodeDetector build ()

Builds a barcode detector instance using the provided settings. If the underlying native implementation is unavailable (e.g. hasn't been downloaded yet), the detector will always return an empty result set. In this case, it will report that it is non-operational via isOperational().

Note that this method may cause blocking disk reads and should not be called on an application's main thread. To avoid blocking the main thread, consider moving Detector construction to a background thread using AsyncTask. Enable StrictMode to automatically detect blocking operations on the main thread.

Returns

public BarcodeDetector.Builder setBarcodeFormats (int format)

Bit mask (containing values like QR_CODE and so on) that selects which formats this barcode detector should recognize.

The full list of supported format constants is:

By default, the detector will recognize all supported formats. This corresponds to the special ALL_FORMATS constant.
