我稍微研究了下发如果遇到这种背景花里胡哨的并且二维码没有预留白边，opencv定位二维码就变的有点艰难了

响应速度不错，可惜不支持条码扫描

有对应的java方法吗,或者用c++在源码里如何修改?

sample直接依赖library出现闪退。

由于二维码的编码格式问题,导致解析后中文乱码,
这边没有对外暴露ZXING的DecodeHintType.CHARACTER_SET的字符编码格式方法吗?

open scanview 界面打开什么也不干，有时一分钟不到就崩溃，希望能改进下这个稳定性问题

编译报这个错误:
ERROR: Manifest merger failed with multiple errors, see logs

建议作者大大能改成，解码完成之后不销毁NativeSdk，让其可以连续扫码，比如我扫了一个码之后，我不退出界面，而是换一个码，也能同样扫出来，或者我一个页面有多个码，都能全部识别出来

无论这个图片上的二维码多清晰,还是识别不出来,谢谢!

扫码时会进行频繁方大，有时候刚看到二维码就进行方法，是够提供方法可以把方大关掉，
聚焦问题，感觉摄像头采集不清晰，每次聚焦要很长时间，

打开扫描页面什么都不扫描关闭页面紧接着在次打开就会出现无法打开相机的错误，是不是我哪里写的不对呢

1.放大问题，放大有点着急，用户还没有对准二维码的时候就放大了，而且放大后的二维码大于扫描框，微信放大若干次后，二维码也不会大于扫描框，这时候用户会拉后手机位置
2.对于透视的码识别率很低，像上下左右倾斜，左上坐下，右上右下，实际生产环境中，码可能在不同的位置，这时候如果不上前对正还能识别，那就太赞了，微信在这方面做的很不错
3.对面有光时识别不了，这个开源框架大部分都没有解决这个问题
这段时间正在为货架二维码识别速率低的问题发愁，提出的问题可能不切实际，还请见谅

建议增加设置ScanActivity，setTitle（“”），showAlbum(boolean)方法

大佬，又发现你一个bug，就是在ScanActivity这个页面内申请权限，然后扫码就会有问题，导致一直扫一直扫，但是没有结果
原因是因为在这边BarCoderView这个类里面
private void startCameraById(int cameraId) {
try {
mCameraId = cameraId;
mCamera = Camera.open(cameraId);
mCameraSurface.setCamera(mCamera);
} catch (Exception e) {
e.printStackTrace();
if (mScanListener != null) {
mScanListener.onOpenCameraError();
}
}
}
如果没有权限的话 Camera.open就会异常，然后 mCameraSurface.setCamera(mCamera) 不会去执行，导致setCamera这个方法里面getHolder().addCallback(this) 不会去执行，虽然申请完权限以后，这边能执行到，但是时机不对了，surfaceCreated这个不会回调，里面的mSurfaceCreated就永远为false

onScanSuccess 里执行UI操作，不报错，但会导致ANR，里面另起UI线程执行UI操作则没问题

@OverRide
public void onScanSuccess(final String result) {
Log.e("onScanSuccess", result);
mSoundPoolUtil.play();
mScanView.stopScan();

   //不报错，不弹框，执行这个后，按返回  ANR
    new AlertDialog.Builder(ScanActivity.this).setTitle("最新通知").setMessage(result)
            .setCancelable(true).setOnDismissListener(new DialogInterface.OnDismissListener() {
        @Override
        public void onDismiss(DialogInterface dialogInterface) {
            mScanView.startScan(); // 显示扫描框，并开始识别
        }
    }).show();

   //不报错，弹框，执行这个后，按返回  正常
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            new AlertDialog.Builder(ScanActivity.this).setTitle("最新通知").setMessage(result)
                    .setCancelable(true).setOnDismissListener(new DialogInterface.OnDismissListener() {
                @Override
                public void onDismiss(DialogInterface dialogInterface) {
                    mScanView.startScan(); // 显示扫描框，并开始识别
                }
            }).show();
        }
    });

}

您好，在使用最新的Demo时，长时间运行依然会出现崩溃，三星C7和mate10都会出现（运行扫描后静置，几分钟后就会出现），频繁长时间使用也会出现

现在会出现一个很尴尬的情况对准任意位置都会一直放大镜头这样有点不太好吧。

如果二维码周围有一圈黑色就无法识别了？请问这种情况有什么解决方案吗？

换了好几个浏览器都是卡在下载.so文件时下载中断或者下载失败，也换电脑了也下载不了

距离很近的时候也会频繁放大，有些页面没有二维码也会放大（比如当前页面），建议整体效果向微信看齐

横屏会崩溃，二维码没在扫码的那个正方形内，是在屏幕上扫码框正方形外也能扫成功

使用ScanView来自定义界面时，界面黑屏，没有显示相机视野，也无法进行扫描

大佬，不知道是不是我用的姿势不对，
“点击扫码"->"调起相机扫码"->”点击右上角相册选取二维码图片"【正常操作没问题，但是如果选取照片的时候，相机正好也对着二维码的话， 会先识别相机下的二维码并回调处理，然后按返回键后又会回到选择图片页】
感谢大佬提供，大佬辛苦

我的红米note 8pro打不开闪光灯的时候没反应，希望作者能够帮忙解决一下下哦！

楼主，崩溃的频率很高，在扫码界面

感谢大神的付出，识别效果高，但是在使用过程中出现，长时间运行会崩溃的现象。哪怕手机打开扫描界面后什么都不扫，放在那不动，隔几分钟就会出现崩溃。集成到自己的APK里是报的内存溢出（使用的是ScanActivity，自己加了数据处理的代码），

用您的demo是另一个错误。

在Demo外面打开闪光灯后，进入Demo,遮住摄像头后，仍提示打开闪光灯

使用0.6APK，在测试扫描时，还没对准二维码，就开始放大，而且不是放大一次，是持续的放大，经过多次测试，发现不管对准键盘，还是对准电脑屏幕，也不管屏幕里面是否存在二维码，反正就是会放大，而且确实是多次放大，不断的去放大。不过二维码识别还可以，支持

完全扫不出来

implementation project(':czxing')
打包时会报找不到libczxing.so，
implementation 'me.devilsen:CZXing:0.8.3'
则不会报找不到库错误

看了libs目录下确实没有找到这个库

这个是我司的一个设备的二维码，印刷是有点问题，不清晰，但是使用微信和我查查都能秒扫出来，这个库一次没有扫出来

打开闪光灯后还是提示“点击打开闪光灯”，应该更改为“点击关闭闪光灯”。

比如我在activity里面创建这个对象，然后activity destroy之后，BarcodeReader这个对象被回收，会自己调用finalize 方法，然后NativeSdk.getInstance().destroyInstance(_nativePtr);
这边必崩溃
我把BarcodeReader 创建出来的对象改为static 就没问题了

还有一个问题，我看到有人已经提过，就是打开扫码页，退出后再马上进入，测试的小米4.4.4的手机会黑屏，如果等个10秒再进入，就不会黑屏

为什么这个二维码Demo的app识别不出来呢
