34 public static final String ACTION = "com.google.zxing.client.android.SCAN";
37 * By default, sending Scan.ACTION will decode all barcodes that we understand. However it
38 * may be useful to limit scanning to certain formats. Use Intent.putExtra(MODE, value) with
39 * one of the values below (optional).
41 public static final String MODE = "SCAN_MODE";
44 * Decode only UPC and EAN barcodes. This is the right choice for shopping apps which get
45 * prices, reviews, etc. for products.

60 * If a barcode is found, Barcodes returns RESULT_OK to onActivityResult() of the app which

85 * The data to encode. Use Intent.putExtra(DATA, data) where data is either a String or a

98 * The barcode format to be displayed. If this isn't specified or is blank,
