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 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);

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.
