E/libc: Access denied finding property “vendor.camera.aux.packagelist“

输出台日志：E/libc: Access denied finding property “vendor.camera.aux.packagelist”
前提：1.app有各类权限
2.app代码无明显问题
3.常见于扫码
4.画面很模糊，或者说像素很低，扫码小概率扫不出来

代码如下：

        parameters.setPreviewSize(cameraResolution.x, cameraResolution.y);
        camera.setParameters(parameters);
        camera.setDisplayOrientation(90);

老的camera启动前设置参数，参数中的x和y得来的方式如下：
大概意思就是根据屏幕尺寸来计算的，遍历摄像头支持的所有分辨率，然后计算的：
笔者错误在于MAX_PREVIEW_PIXELS 这个值是老的 仅仅为800 * 1080 小于目前市面上的手机支持的屏幕像素 如p40为2340 × 1080
导致最终的的结果很小，以至于显示的就很模糊 但是未影响二维码解码
