How to use this Library:

After importing this library, use the following lines to use this library. The following lines are used to generated the QR Code

// Initializing the QR Encoder with your value to be encoded, type you required and Dimension
QRGEncoder qrgEncoder = new QRGEncoder(inputValue, null, QRGContents.Type.TEXT, smallerDimension);
qrgEncoder.setColorBlack(Color.RED);
qrgEncoder.setColorWhite(Color.BLUE);
try {
  // Getting QR-Code as Bitmap
  bitmap = qrgEncoder.getBitmap();
  // Setting Bitmap to ImageView
  qrImage.setImageBitmap(bitmap);
} catch (WriterException e) {
  Log.v(TAG, e.toString());
}

The following lines are used to generated the QR Code without margin/default border

// Initializing the QR Encoder with your value to be encoded, type you required and Dimension
QRGEncoder qrgEncoder = new QRGEncoder(inputValue, null, QRGContents.Type.TEXT, smallerDimension);
qrgEncoder.setColorBlack(Color.RED);
qrgEncoder.setColorWhite(Color.BLUE);
try {
  // Getting QR-Code as Bitmap
  bitmap = qrgEncoder.getBitmap(0);
  // Setting Bitmap to ImageView
  qrImage.setImageBitmap(bitmap);
} catch (WriterException e) {
  Log.v(TAG, e.toString());
}

The following lines are used to generated the Bar Code

BarcodeEncoder barcodeEncoder = new BarcodeEncoder(inputValue, BarcodeFormat.CODE_128, 800);
bitmap = barcodeEncoder.getBitmap(2);  // Margin of 2 pixels
// Now you can use this bitmap as needed, e.g., display it in an ImageView
qrImage.setImageBitmap(bitmap);

Save QR Code as Image

// Save with location, value, bitmap returned and type of Image(JPG/PNG).
QRGSaver qrgSaver = new QRGSaver();
qrgSaver.save(savePath, edtValue.getText().toString().trim(), bitmap, QRGContents.ImageType.IMAGE_JPEG);
