Android的zxing NotFoundException [英] Android zxing NotFoundException

问题描述

我用zxing脱code QR code图像，但它总是返回NotFoundException。网上去codeR在 http://zxing.org/w/de$c $ c.jspx 扫描这些图像完全没有问题，所以它应该是能够做到这一点在我的应用程序。 我使用这个code：

I'm using zxing to decode QRcode images, but it always returns a NotFoundException. The online decoder at http://zxing.org/w/decode.jspx scans these images perfectly fine, so it should be able to do so in my app. I'm using this code :

String path = Environment.getExternalStorageDirectory().getPath()+"/QRPictures/QRTest.bmp";
Bitmap bmp = BitmapFactory.decodeFile(path);
int[] pixels = new int[bmp.getWidth()*bmp.getHeight()];
bmp.getPixels(pixels, 0, bmp.getWidth(), 0, 0, bmp.getWidth(), bmp.getHeight());
LuminanceSource source = new RGBLuminanceSource(bmp.getWidth(), bmp.getHeight(), pixels); 
BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
Reader reader = new MultiFormatReader();
try {
    Result result = reader.decode(bitmap);
    String contents = result.getText(); 
    Log.d(TAG, content);
} catch (NotFoundException e) {
    Log.d(TAG, "NFE");
} catch (ChecksumException e) {
    Log.d(TAG, "CSE");
} catch (FormatException e) {
    Log.d(TAG, "FE");
} 

你能帮助这个好吗？
