Project Origins

This project originated at https://github.com/EdwardvanRaak/MaterialBarcodeScanner, however, after the code had not been touched in 3 years, it became nessisary to fork the repository, and make some needed improvments. Once I get it building again, the namespace will be changed, to avoid collisions with the original.

Setup

1. Provide gradle dependency

The library is hosted on Bintray at: https://bintray.com/bpappin/pappin/material-barcode-scanner

Add to your repository list:

repositories {
    maven {
        url  "https://dl.bintray.com/bpappin/pappin"
    }
}

Add the library to your dependencies:

implementation 'com.github.pappin.mbs:mbs-lib:1.0.1'

2. Build a MaterialBarcodeScanner

    private void startScan() {
        /**
         * Build a new MaterialBarcodeScanner
         */
        final MaterialBarcodeScanner materialBarcodeScanner = new MaterialBarcodeScannerBuilder()
                .withActivity(MainActivity.this)
                .withEnableAutoFocus(true)
                .withBleepEnabled(true)
                .withBackfacingCamera()
                .withText("Scanning...")
                .withResultListener(new MaterialBarcodeScanner.OnResultListener() {
                    @Override
                    public void onResult(Barcode barcode) {
                        barcodeResult = barcode;
                        result.setText(barcode.rawValue);
                    }
                })
                .build();
        materialBarcodeScanner.startScan();
    }

Hook it up to a button

  fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startScan();
            }
        });

3. Start scanning!

Additional Setup

Center tracking mode

By default a barcode is tracked/highlighted at the location at which it was found. With center tracking mode a square image will be shown during scanning that will turn green when a barcode is found. Please note that you can still scan a barcode outside the center tracker! This is purely a visual change.

To activate center tracking mode simply call the following builder method:

.withCenterTracker()

If you want to provide your own image for the tracker you can use:

.withCenterTracker(R.drawable.your_tracker_image, R.drawable.your_detected_state_tracker_image):

Exclusive barcode scanning

In some situations you might want to scan for only a certain type of barcode like QR-Codes or 2D barcodes. You can do this with the following builder methods:

.withOnlyQRCodeScanning()
.withOnly3DScanning()
.withOnly2DScanning()

If you want to scan for a very specific combination of barcodes you can setup the builder like this:

.withBarcodeFormats(Barcode.AZTEC | Barcode.EAN_13 | Barcode.CODE_93)
