基于MT6737平臺(tái)，6735m架構(gòu)

HalSensorList.buildStaticInfo.cpp

先看結(jié)構(gòu)體：

staticchar const*constkStaticMetadataTypeNames[] = {    "LENS",    "SENSOR",    "TUNING_3A",    "FlashLIGHT",    "SCALER",    "FEATURE",    "CAMERA",    "REQUEST",    NULL};這個(gè)結(jié)構(gòu)體中成員名字都是字符串，在metadata目錄中，每個(gè)sensor的metadata文件名字都包含其中一個(gè)字符串。
config_static_metadata.lens.s5k3h7yxmipiraw.h
config_static_metadata.PRoject.camera.s5k3h7yxmipiraw.h
config_static_metadata.project.flashlight.s5k3h7yxmipiraw.h
config_static_metadata.sensor.s5k3h7yxmipiraw.h
config_static_metadata.tuning_3a.s5k3h7yxmipiraw.h
config_static_metadata_feature.h
config_static_metadata_request_commonType.h
config_static_metadata_scaler.h
其中config_static_metadata.sensor.s5k3h7yxmipiraw.h這個(gè)文件會(huì)定義：STATIC_METADATA2_BEGIN(DEVICE, SENSOR, SENSOR_DRVNAME_S5K3H7YX_MIPI_RAW)
SENSOR和文件名字中的sensor一一對(duì)應(yīng)，其他文件類似。
函數(shù)會(huì)
staticMBOOLimpBuildStaticInfo(    Info const&     rInfo,    IMetadata&      rMetadata)
會(huì)解析出文件句柄：
      char const*const pTypeName = kStaticMetadataTypeNames[i];  ----------->前面的字符串機(jī)構(gòu)體
        String8 const s8Symbol_Sensor = String8::format("%s_DEVICE_%s_%s", PREFIX_FUNCTION_STATIC_METADATA, pTypeName, rInfo.getSensorDrvName().string());        status = impConstructStaticMetadata_by_SymbolName(s8Symbol_Sensor, rInfo, rMetadata);
