Android 查询设备信息c/c++常用方法

Android查询设备属性c/c++方法

在Android开发中,可以通过c接口直接获取设备属性,系统接口为:
int __system_property_get(const char* name, char* value);

实现代码

下面是作者使用的常用属性

#include 

typedef struct SDeviceInfo
{
    char szId[128];
    char szPlatform[128];
    char szHardware[128];

    char szBrand[128];
    char szManufacturer[128];
    char szCpuAbi[128];
    char szCpuAbiList[256];
    char szModel[128];
    char szDevice[128];
    char szBoard[128];
} SDeviceInfo;

static SDeviceInfo g_devInfo;
__system_property_get("ro.build.id",             g_devInfo.szId);
__system_property_get("ro.hardware",             g_devInfo.szHardware);
__system_property_get("ro.board.platform",       g_devInfo.szPlatform);
__system_property_get("ro.product.brand",        g_devInfo.szBrand);
__system_property_get("ro.product.manufacturer", g_devInfo.szManufacturer);
__system_property_get("ro.product.cpu.abi",      g_devInfo.szCpuAbi);
__system_property_get("ro.product.cpu.abilist",  g_devInfo.szCpuAbiList);
__system_property_get("ro.product.model",        g_devInfo.szModel);
__system_property_get("ro.product.device",       g_devInfo.szDevice);
__system_property_get("ro.product.board",        g_devInfo.szBoard);

[device_info_init] ro.build.id       : HUAWEIKANT-350S
[device_info_init] ro.board.platform : honghu818
[device_info_init] ro.hardware       : honghu8xx
[device_info_init] ro.product.brand  : HUAWEI
[device_info_init] ro.product.manufacturer: HUAWEI
[device_info_init] ro.product.cpu.abi: arm64-v8a

[device_info_init] ro.product.model  : KANT-350S
[device_info_init] ro.product.device : HWKANT-350S
[device_info_init] ro.product.board : KANT

ro.product 属性

* ro.product.brand	品牌客户名称,
* ro.product.model	终端用户可见的产品名称,可以有空格
* ro.product.manufacturer	产品/硬件的制造商名称
* ro.product.name	手机正式名称客户项目代号,不要有空格,如果包含空格,会导致Google账号无法登陆
* ro.product.board	采用的底板/处理器客户项目代号
* ro.product.device	采用的设备,作用范围:adb shell进去时显示的名称客户项目代号,不要有空格
* ro.build.product	已经过时,现在使用“ro.product.device”,等同于“ro.product.device”

######## UBOOTENV VARIBLES - r/w as system properties ##########
#
#  Now we can load ubootenv varibles to system properties.
#  We use a special prefix ("ubootenv.var" as default) to indicate that the 'property'
#  actually is an ubootenv varible.
#
#  A ubootenv 'property' will be initialized during system booting. And when user set
#  a different value, it will be written back to ubootenv device immediately.
