zxing

I was having some problem when trying to generate QR code in Android Programming. Here is the Tutorial I followed. When my generate button on click, I am calling this method: private void generateQR(){ String qrInputText = "test"; //Find screen size WindowManager manager = (WindowManager) getSystemService(WINDOW_SERVICE); Display display = manager.getDefaultDisplay(); Point point = new Point(); display.getSize(point); int width = point.x; int height = point.y; int smallerDimension = width < height ? width : height; smallerDimension = smallerDimension * 3/4; //Encode with a QR Code image

I have seen few QR codes with company logo at the center. Is it possible to generate a QR code with a any logo in android? If possible kindly explain the way for doing it. Currently I am using Zxing for generating QR codes. A QR code is a quick response code, You can use zxing to make the QR codes. but by default there are no company logos present there at center or any other part. What you can do is create a QR code and on top of it draw the logo image of the company With reference to the guide and source code provided at Generating a qr code with a logo please find the sample Android code

I am currently developing a scanner that reads multiple QR codes found in one image. I manage to read the QR codes in the image but it's giving me inconsistent results. Assuming there are 4 QR codes in the image, sometimes I can read 2 and sometimes 3 or just 1. Unlike in the original scanner (ZXing Scanner) it decodes fast. While in my case, I have to make sure there is enough light and the image is not blurred to decode it. I am using the QRCodeMultiReader to decode the image. Currently using ZXing Library to create the application. Below is the snippet of my code: public void onPictureTaken

I am using Zxing library to generate a barcode in my Android application Intent intent = new Intent("com.google.zxing.client.android.ENCODE"); intent.putExtra("ENCODE_FORMAT", "UPC_A"); intent.putExtra("ENCODE_DATA", "55555555555"); startActivityForResult(intent,0); Is there anyway to save the generated image in my application which is calling Zxing? I see that in my onActivityResult I get intent null. Thanks in advance for your help Take the views cache and save it in bitmap something like this View myBarCodeView = view.getRootView() //Else this might return null myBarCodeView

I'm trying to rotate Zxing display after reading a few questions and posts about the issue. After following the instructions, the display did rotate, but the rectangle of the scanner is not positioned as it should (as can be seen on the image attached). This is what I have done: in CameraConfigurationManager: camera.setDisplayOrientation(90); in DecodeHandler.java byte[] rotatedData = new byte[data.length]; for (int y = 0; y < height; y++) { for (int x = 0; x < width; x++) rotatedData[x * height + height - y - 1] = data[x + y * width]; } int tmp = width; width = height; height = tmp; in

一，首先在maven中添加一下jar包 <dependency> <groupId>com.google.zxing</groupId> <artifactId>core</artifactId> <version>3.3.0</version> </dependency> 然后新建个工具类 QrcodeUtil // 图片宽度的一半 private static final int width = 500; private static final int height = 500; private static final int BLACK = 0xFF000000; private static final int WHITE = 0xFFFFFFFF; //生成二维码存放路径 private static final String destImagePath="d:\\qrcode.jpg"; //扫描二维码跳转页面 private static final String content="http://www.baidu.com"; // 二维码写码器 private static MultiFormatWriter multiWriter = new MultiFormatWriter(); /** * 生成二维码 * * @param content
