Barcode Generator

The Barcode Generator is a simple tool to generate barcodes directly from the Scandit SDK. In this guide, we will show you how to use the Barcode Generator to generate barcodes and QR codes.

The Barcode Generator supports the following formats:

  • Code 39
  • Code 128
  • EAN 13
  • UPCA
  • ITF
  • QR
  • DataMatrix

Prerequisites​

Before starting with adding a capture mode, make sure that you have a valid Scandit Data Capture SDK license key and that you added the necessary dependencies. If you have not done that yet, check out this guide.

note

You can retrieve your Scandit Data Capture SDK license key, by signing in to your account Dashboard.

Generating Barcodes​

To generate barcodes, you need to create a DataCaptureContext.

With the context you can then instantiate a BarcodeGeneratorBuilder, and use the method of BarcodeGenerator for the symbology you are interested in, in this example Code 128.

You can configure the colors used in the resulting image:

DataCaptureContext dataCaptureContext = DataCaptureContext.forLicenseKey(licenseKey);
BarcodeGenerator.Code128BarcodeGeneratorBuilder builder = new BarcodeGenerator.code128BarcodeGeneratorBuilder(dataCaptureContext)
    .withBackgroundColor(Color.WHITE)
    .withForegroundColor(Color.BLACK);

When the builder is configured get the BarcodeGenerator and try to generate the image:

try {
    BarcodeGenerator generator = builder.build();
    Bitmap image = generator.generate(dataString, 200);
    // Use the image
} catch (Exception exception) {
    // Handle the error
    exception.printStackTrace();
}

See the complete API reference for more information.

Generating QR Codes​

To generate barcodes, you need to create a DataCaptureContext.

With the context you can then instantiate a QRCodeBarcodeGeneratorBuilder using the method of BarcodeGenerator specific for QR codes.

You can configure the colors used in the resulting image, and the two settings that can be configured for QR codes: QRCodeBarcodeGeneratorBuilder.errorCorrectionLevel and QRCodeBarcodeGeneratorBuilder.versionNumber.

DataCaptureContext dataCaptureContext = DataCaptureContext.forLicenseKey(licenseKey);
BarcodeGenerator.QrCodeBarcodeGeneratorBuilder builder = new BarcodeGenerator.QrCodeBarcodeGeneratorBuilder(dataCaptureContext)
    .withBackgroundColor(Color.WHITE)
    .withForegroundColor(Color.BLACK)
    .withErrorCorrectionLevel(QrCodeErrorCorrectionLevel.MEDIUM)
    .withVersionNumber(4);

When the builder is configured get the BarcodeGenerator and try to generate the image:

try {
    BarcodeGenerator generator = builder.build();
    Bitmap image = generator.generate(dataString, 200);
    // Use the image
} catch (Exception exception) {
    // Handle the error
    exception.printStackTrace();
}
