前言Camera架构本身内容就很多，因此在GMS中关于Camera的测试项很多，CTS/CTSV/ITS(ctsv中)/GTS/CTS-ON-GSI/VTS中都存在相关测试模块。测试了与Camera相关的所有功能。 一时总结不全，不断完善中 经验camera问题可能功能问题、也可能效果，大部分是配置问题。camera参数非常多而且很多之间存在相互关联，某处参数修改可能影响与之关联的参数。 简单记录下一般如何处理 根据报错直接修改有些报错很明显的，直接看报错就能定位到问题，如果camera相关比较熟悉的话 直接修改。 The static info key 'android.hotPixel.availableHotPixelModes' FAST and HIGH_QUALITY mode must both present or both not present android.hotPixel.availableHotPixelModes这个配置中FAST和HIGH_QUALITY要同时存在或者不存在。 CONFIG_METADATA_BEGIN(MTK_HOT_PIXEL_AVAILABLE_HOT_PIXEL_MODES) CONFIG_ENTRY_VALUE(MTK_HOT_PIXEL_MODE_FAST, MUINT8) CONFIG_ENTRY_VALUE(MTK_HOT_PIXEL_MODE_HIGH_QUALITY, MUINT8) CONFIG_METADATA_END() 查看相关代码CTS源码在工程目录下的cts/目录中(不过这里的一般比较老，主要参考下面网址查看)，很容易找到源码(CTS-ON-GSI也基本可以参考CTS的代码)。然后根据报错，找到问题点。 部分工具没有源码，一般能通过反编译工具中的apk，基本也能看出逻辑，找出问题。 导出手机中camera参数通过下面命令，可以导出手机中camera相关的参数。 adb shell dumpsys media.camera -v 1 > xxx.log 基本检查确认一些camera的基本检查 配置。 16倍数分辨率的配置一般是16的倍数，如720x1280，其中720 1280都是16的倍数。 基本支持的检查，每个摄像头最好单独确认下
