zxing 1.8.4
On the mate8 phone code recognition difficult

is Zbar relative to zxing recognition degree high?
What is the difference between them?

@ethanhua 我现在遇到华为的双摄像头的系列手机，也是扫码困难，只要是双摄像头的好像都无法对焦，您的问题解决了吗？

主要原因是因为camera设置的previewsize太小，导致显示的画面极其模糊

I have a same problem.

Hi @ethanhua - Can you tell me if you are using zxing or zbar? Also can you tell me if the sample apps work better or worse? Can you also tell me if the issue has been resolved with 1.9 for you?

[wangyuetingtao]

add this to manifest.xml ：

<uses-feature android:name="android.hardware.camera.autofocus"/>

hello,i am from china ,my english is poor,i am sorry.my question is that when scanning ,the scan line dont
move up and down, but just stay at middle of surface view.Could you help to tell me how to solve this problem? thank you very much!

[ethanhua]

@idealcn 你的问题属于UI上的范围 你自己定义一个view 继承ViewFinderView 去间隔绘制对应的扫码线即可

@ethanhua I solved this problem with PR #293

I have a same problem in HUAWEI Mate9 with zxing 1.9.3

[bmbogdan]

This problem occurs even on huawei p8/p9 lite. Any updates?

华为p9 华为v8都有这样的问题，可能双摄都有问题 zxing 1.9.3
