ScannerFragment is an easy way to add barcode scanning functionality to your app. To use, follow these steps:

Obtain CAMERA permissions. ScannerFragment makes no attempt to request permissions on its own. Failure to obtain CAMERA permissions will cause scanning to fail.
Instantiate an instance of ScannerFragment.
Register a listener to receive barcode scanning results.
Use FragmentManager to add the fragment to your activity. For best results, add fragment should be added within a 16x9 container.

Constants

ARG_BARCODE2_TYPES

public static final String ARG_BARCODE2_TYPES

A string array argument for specifying barcode types to scan for. Each string should be the name() of a BarcodeType2. For example:

arguments.putStringArray(ScannerFragment.ARG_BARCODE2_TYPES, new String[] {BarcodeType2.QR.name(), BarcodeType2.QR_MICRO.name()});

Constant Value: "barcode2_types"

ARG_BARCODE_TYPES

public static final String ARG_BARCODE_TYPES

This constant is deprecated.
As of Scanner 2

A string array argument for specifying barcode types to scan for. Each string should be the name() of a BarcodeType. For example:

arguments.putStringArray(ScannerFragment.ARG_BARCODE_TYPES, new String[] {BarcodeType.QR.name(), BarcodeType.QR_MICRO.name()});

Constant Value: "barcode_types"

ARG_CAMERA_ID

public static final String ARG_CAMERA_ID

A String argument for specifying the desired camera to use

arguments.putString(ScannerFragment.ARG_CAMERA_ID, 1);

Constant Value: "camera_id"

ARG_LICENSE_KEY

public static final String ARG_LICENSE_KEY

This constant is deprecated.
As of Scanner 2

A string argument for specifying a custom license key.

Constant Value: "license_key"

ARG_SCANNING_RECT

public static final String ARG_SCANNING_RECT

A parcelable argument for specifying the scanning rect. For example:

arguments.putParcelable(ScannerFragment.ARG_SCANNING_RECT, new ScanningRect(.5f, .5f));

Constant Value: "scanning_rect"

ARG_ZOOM_IN_MODE

public static final String ARG_ZOOM_IN_MODE

A boolean argument for barcode run in zoom mode. For example:

arguments.putBoolean(ScannerFragment.ARG_ZOOM_MODE, true);

Constant Value: "zoom_in_mode"
