I can't get anything by using this demo(new and old demo) in Android 6.0? why

[pangpangshui]

I get some debug info, but it is so long that I just clip some like this:

W GLConsumer: [SurfaceTexture-0-21322-0] bindTextureImage: clearing GL error: 0x502

Can you give me a hand? And may I ask which system version in your Android phone?

What's your android device model?

[pangpangshui]

Redmi 2A with Android 5.1 and Redmi Note 4 with Android 6.0

Also I found the reason why this bug happend may be the Android 6.0 system. Just like this

When you run demo, is a black screen, or camera image displayed, but can not analyse the data?

[pangpangshui]

I found that I did't change the target SDK to API 23. When I changed it, the error message(W GLConsumer: [SurfaceTexture-0-21322-0] bindTextureImage: clearing GL error: 0x502) disappeared, but the phone got a black screen just like I couldn't call the camera. And the MIUI didn't give me a tips that permiting to call camera, so I guess Android 6.0 permission would be the reason. But have no idea how to fix it. @188080501 -_-

[188080501]

have no idea too, sorry T.T

[pangpangshui]

Okay, thanks anyway.
By the way, after google it, I think I may be connected with opengl and it is neccesarry to override Java function. I am not familiar with Java, so there's nothing I can do about the problem. May be like this http://maninara.blogspot.sg/2015/03/render-camera-preview-using-opengl-es.html. But I don't know how to modify this project.
Hope someone can fix this problem.

Can I ask what version is qzxing that you use? If you use a new one, may be you can fix this problem.

[188080501]

Currently based on zxing development, not qzxing.

[pangpangshui]

Thanks, I get it.
If you update your code which can fit Android 6.0, please sent me a message.
Best wishes for you.

[188080501]

you tried to declare the camera permissions?

[pangpangshui]

Yes, but I couldn't do it successfully with Java because I am not familiar with Java at all. I have no idea that whether it can work well or not if I add the camera permission. Hope you can try.

[pangpangshui]

I fixed it when I use Qt5.9.1 compiling my project. Thanks.
