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.
