QR code decoding images using zxing android

Question

I am doing a simple application on Android which is the following:

Putting a QR code Image in the Drawable file of the application. By a ButtonClick, it should be decoded and Display the result (using Zxing library).

I have made the same application on Java (the decoding was then using BufferedImageLuminanceSource class).

In my android application, I used the RGBLuminanceSource class as follows:

LuminanceSource source = new RGBLuminanceSource(width, height, pixels)BinaryBitmap binaryBitmap = new BinaryBitmap(new HybridBinarizer(source));

The problem I am facing here is that: the image has to be too small to be decoded by the android application(and I had to try many sizes to finally got one where the QR code Image is decoded). Meanwhile the same images were decoded easily using the BufferedImageLuminanceSource in Java application without any need to be resized.

What to do to avoid this resizing Problem?

Its too late but it can be help to others,

So we can get Qr code Info from Bitmap using Zxing library.

 Bitmap generatedQRCode;
    int width = generatedQRCode.getWidth();
    int height = generatedQRCode.getHeight();
    int[] pixels = new int[width * height];
    generatedQRCode.getPixels(pixels, 0, width, 0, 0, width, height);

    RGBLuminanceSource source = new RGBLuminanceSource(width, height, pixels);

    BinaryBitmap binaryBitmap = new BinaryBitmap(new HybridBinarizer(source));

    Reader reader = new MultiFormatReader();
    Result result = null;
    try {
        result = reader.decode(binaryBitmap);
    } catch (NotFoundException e) {
        e.printStackTrace();
    } catch (ChecksumException e) {
        e.printStackTrace();
    } catch (FormatException e) {
        e.printStackTrace();
    }
    String text = result.getText();
    textViewQRCode.setText(" CONTENT: " + text);

didnt work for me dont know why, cannot recognize code128 barcode :( — user3162662, Mar 19 '19 at 06:57
