1. Android Device信息知多少：

通常，一个设备的信息包含下面这几类：

（1）厂商相关信息，例如手机制造商，主板厂商；

（2）硬件相关信息，例如cpu型号，cpu指令集，主板型号，显示屏参数，蓝牙参数，GPS参数，硬件序列号，无线固件版本；

（3）编译相关信息，例如编译时间，编译类型；

（4）入网相关信息，例如IMEI，IMSI；

（5）虚拟机相关信息，入art虚拟机信息；

（6）其它，例如启动程序版本号（即bootloader编译版本）。

2. 设备信息的获取：

可以使用Android系统提供的API接口来获取，也可以使用诸如getProp的命令来获取，还可以使用__system_property_get等属性获取函数来获取。。

用API接口获取device信息：

public static String getDeviceInfo() {
        StringBuffer sb = new StringBuffer();
        sb.append("主板：" + Build.BOARD);
        sb.append("\n系统启动程序版本号：" + Build.BOOTLOADER);
        sb.append("\n系统定制商：" + Build.BRAND);
        sb.append("\ncpu指令集：" + Build.CPU_ABI);
        sb.append("\ncpu指令集2：" + Build.CPU_ABI2);
        sb.append("\n设置参数：" + Build.DEVICE);
        sb.append("\n显示屏参数：" + Build.DISPLAY);
        sb.append("\n无线电固件版本：" + Build.getRadioVersion());
        sb.append("\n硬件识别码：" + Build.FINGERPRINT);
        sb.append("\n硬件名称：" + Build.HARDWARE);
        sb.append("\nHOST:" + Build.HOST);
        sb.append("\n修订版本列表：" + Build.ID);
        sb.append("\n硬件制造商：" + Build.MANUFACTURER);
        sb.append("\n版本：" + Build.MODEL);
        sb.append("\n硬件序列号：" + Build.SERIAL);
        sb.append("\n手机制造商：" + Build.PRODUCT);
        sb.append("\n描述Build的标签：" + Build.TAGS);
        sb.append("\nTIME:" + Build.TIME);
        sb.append("\nbuilder类型：" + Build.TYPE);
        sb.append("\nUSER:" + Build.USER);

        return sb.toString();
    }

getProp来获取设备信息：

底层接口：
 
另外,在程序中,你可以用__system_property_get函数获取build.prop中的具体属性值,例如:
    __system_property_get("ro.build.version.release", version_release); 
得到的是手机采用的Android版本,最常见的有: 2.1, 2.2, 2.3 。
