本文介绍了Android系统中Build类包含的各种信息，如设备型号、制造商等，并提供了检查手机类型的示例代码。

最近正在以某亿级APP源码为模板学习android的各方面内容，包括设计、开发、各种类的使用，已经最重要的就是思路。

在官方文档中可以查到Build类中有如下常量：

public static final String	BOARD	The name of the underlying board, like "goldfish".主板名称
public static final String	BOOTLOADER	The system bootloader version number.系统引导程序版本号
public static final String	BRAND	The brand (e.g., carrier) the software is customized for, if any.android系统定制商
public static final String	CPU_ABI	The name of the instruction set (CPU type + ABI convention) of native code.CPU 和ABI的本地代码指令集
public static final String	CPU_ABI2	The name of the second instruction set (CPU type + ABI convention) of native code.
public static final String	DEVICE	The name of the industrial design.设备参数
public static final String	DISPLAY	A build ID string meant for displaying to the user显示屏参数
public static final String	FINGERPRINT	A string that uniquely identifies this build.硬件名
public static final String	HARDWARE	The name of the hardware (from the kernel command line or /proc).内核命令行中的硬件名
public static final String	HOST
public static final String	ID	Either a changelist number, or a label like "M4-rc20".修改版本列表
public static final String	MANUFACTURER	The manufacturer of the product/hardware.硬件厂商
public static final String	MODEL	The end-user-visible name for the end product.版本
public static final String	PRODUCT	The name of the overall product.手机厂商
public static final String	RADIO	This field was deprecated in API level 14. The radio firmware version is frequently not available when this class is initialized, leading to a blank or "unknown" value for this string. Use `getRadioVersion()` instead.
public static final String	SERIAL	A hardware serial number, if available.
public static final String	TAGS	Comma-separated tags describing the build, like "unsigned,debug".描述Build的标签
public static final long	TIME
public static final String	TYPE	The type of build, like "user" or "eng".Build的类型
public static final String	USER

通过这些常量就可以获得Android手机的一些设备信息。

例如：

/**
	 * 检查手机类型， 是否是三星 小米 或 普通root机 普通非root机
	 */
	public void checkPhoneType() {
		// 是否是ｒｏｍ为２．３以上的三星非Ｇｏｏｇｌｅ定制手机
		String manufacturer = Build.MANUFACTURER;
		int sdkVersion = Build.VERSION.SDK_INT;
		String model = Build.MODEL;
		String displayStr = Build.DISPLAY;
		String brand = Build.BRAND;

		String phoneInfo = "Product: " + android.os.Build.PRODUCT;
		phoneInfo += ", CPU_ABI: " + android.os.Build.CPU_ABI;
		phoneInfo += ", TAGS: " + android.os.Build.TAGS;
		phoneInfo += ", VERSION_CODES.BASE: "
				+ android.os.Build.VERSION_CODES.BASE;
		phoneInfo += ", MODEL: " + android.os.Build.MODEL;
		phoneInfo += ", SDK: " + android.os.Build.VERSION.SDK;
		phoneInfo += ", VERSION.RELEASE: " + android.os.Build.VERSION.RELEASE;
		phoneInfo += ", DEVICE: " + android.os.Build.DEVICE;
		phoneInfo += ", DISPLAY: " + android.os.Build.DISPLAY;
		phoneInfo += ", BRAND: " + android.os.Build.BRAND;
		phoneInfo += ", BOARD: " + android.os.Build.BOARD;
		phoneInfo += ", FINGERPRINT: " + android.os.Build.FINGERPRINT;
		phoneInfo += ", ID: " + android.os.Build.ID;
		phoneInfo += ", MANUFACTURER: " + android.os.Build.MANUFACTURER;
		phoneInfo += ", USER: " + android.os.Build.USER;

		String device = Build.DEVICE;

		if (model.startsWith("Lenovo")) {
			setLenovoLenovo(true);
		}

		if ("Meizu".equals(brand)) {
			setMZ(true);
		}

		if ((manufacturer != null && manufacturer.trim().contains("samsung") && sdkVersion >= 9)
				&& (model == null || (!model.trim().toLowerCase()
						.contains("google") && !model.trim().toLowerCase()
						.contains("nexus")))) {
			setSamsung(true);
		}

		// 安卓4.0以上rom
		if (sdkVersion >= 14) {
			setSdkGreaterThanApi14(true);
		}
		if (displayStr != null && displayStr.toLowerCase().contains("miui")) {
			setMIUI(true);
		}
		if (brand.equals("Xiaomi") && model.trim().contains("MI 2")) {
			setIsXiaomi2S(true);
		}
		if (brand.equals("Xiaomi") && model.trim().contains("1S")) {
			setIsXiaomi2S(true);
		}
		if (brand.equals("Xiaomi") && model.trim().contains("MI-")) {
			setMIUI(true);
		}

	}

通过这些信息就能区别出手机厂商、品牌和型号信息，从而有针对性的进行操作。

Build类下只有一个方法：getRadioVersion()。

Returns the version string for the radio firmware. May return null (if, for instance, the radio is not currently on).

用于获取无线电固件的版本号，返回值是String。
