Android camera2扫描

camera2扫描获取高清图

先看下google提供的demo https://github.com/googlesamples/android-Camera2Basic
扫描获取高清图也是基于这个demo做了一些修改，遇到一些问题，这边讲述下自己的想法，大佬勿喷。

demo中自定义的AutoFitTextureView 我建议是不要用，它是通过手机的屏幕分辨率来选择的分辨率，现在国产手机分辨率有很多不是16：9，4：3的，所以它这套算法下来，会选取比较低的分辨率，就导致预览的时候模糊看不清。
我个人建议是先选定自己想要的分辨率，（我用的是1080*1920）然后设置使用TextureView设置宽为match_parent,最后动态设置高度为 textureView高度 = textureView宽 * 预览高 / 预览宽

2.Camera2功能支持情况我做的是扫描软件，同时又要求要高清图，为了保证预览无卡顿，所以要做到拍摄图片时，预览不能暂停，但是发现oppo手机不行，取一张图就卡一次，用户体验非常不好，我也傻到联系他们客服（当然客服跟你讲的都是官方话术）这里要感谢一位大佬这是他写 https://www.jianshu.com/p/23e8789fbc10 以下是摘抄

查询Camera2功能支持情况
上面说过, 不是所以手机都支持完整的Camera2功能, 现在都2018了, Camera2出来都有4年左右了, 但估计还有些中低端手机使用的HAL1, 使用HAL1就会导致Camera2一些高级功能都没法使用了, 下面讲一下如何查询设备对应Camera2的支持情况.
INFO_SUPPORTED_HARDWARE_LEVEL
硬件层面支持的Camera2功能等级, 主要分为5个等级:

INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY
INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED
INFO_SUPPORTED_HARDWARE_LEVEL_FULL
INFO_SUPPORTED_HARDWARE_LEVEL_3
INFO_SUPPORTED_HARDWARE_LEVEL_EXTERNAL

LEVEL_LEGACY: 向后兼容模式, 如果是此等级, 基本没有额外功能, HAL层大概率就是HAL1(我遇到过的都是)
LEVEL_LIMITED: 有最基本的功能, 还支持一些额外的高级功能, 这些高级功能是LEVEL_FULL的子集
LEVEL_FULL: 支持对每一帧数据进行控制,还支持高速率的图片拍摄
LEVEL_3: 支持YUV后处理和Raw格式图片拍摄, 还支持额外的输出流配置
LEVEL_EXTERNAL: API28中加入的, 应该是外接的摄像头, 功能和LIMITED类似
各个等级从支持的功能多少排序为: LEGACY < LIMITED < FULL < LEVEL_3
获取等级相关代码

private int isHardwareSupported(CameraCharacteristics characteristics) {Integer deviceLevel = characteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL);if (deviceLevel == null) {Log.e(TAG, "can not get INFO_SUPPORTED_HARDWARE_LEVEL");return -1;}switch (deviceLevel) {case CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_FULL:Log.w(TAG, "hardware supported level:LEVEL_FULL");break;case CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY:Log.w(TAG, "hardware supported level:LEVEL_LEGACY");break;case CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_3:Log.w(TAG, "hardware supported level:LEVEL_3");break;case CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED:Log.w(TAG, "hardware supported level:LEVEL_LIMITED");break;}return deviceLevel;}

. 测试了几款手机 oppo手机的等级就是LEVEL_LEGACY，也就是个five。所以oppo用camera2的话，预览的时候就不要想拿高分辨的图了，也不要拍照，直接获取低分辨率预览图，也是可以使用的。
