在專案的開發中，我們可能會與Build類打交道。例如，根據手機CPU的型別來進行so庫的動態的下載；在使用者登入時，可以獲取使用者手機型號，Android系統版本，手機序列號等資訊。

Build類屬於android.os包下，主要用於記錄裝置硬體和版本資訊。

Build的內部類：VERSION_CODES，記錄Android系統版本號常量，比如重要的14，21，23，24，26。

public static class VERSION_CODES {
public static final int BASE = 1;
public static final int BASE_1_1 = 2;
public static final int CUPCAKE = 3;
public static final int CUR_DEVELOPMENT = 10000;
public static final int DONUT = 4;
public static final int ECLAIR = 5;
public static final int ECLAIR_0_1 = 6;
public static final int ECLAIR_MR1 = 7;
public static final int FROYO = 8;
public static final int GINGERBREAD = 9;
public static final int GINGERBREAD_MR1 = 10;
public static final int HONEYCOMB = 11;
public static final int HONEYCOMB_MR1 = 12;
public static final int HONEYCOMB_MR2 = 13;
public static final int ICE_CREAM_SANDWICH = 14;// 4.0
public static final int ICE_CREAM_SANDWICH_MR1 = 15;
public static final int JELLY_BEAN = 16;
public static final int JELLY_BEAN_MR1 = 17;
public static final int JELLY_BEAN_MR2 = 18;
public static final int KITKAT = 19;
public static final int KITKAT_WATCH = 20;
public static final int LOLLIPOP = 21;// 5.0
public static final int LOLLIPOP_MR1 = 22;
public static final int M = 23;// 6.0
public static final int N = 24;// 7.0
public static final int N_MR1 = 25;
public static final int O = 26;// 8.0
public static final int O_MR1 = 27;

public VERSION_CODES() {
throw new RuntimeException("Stub!");
}
}

Build的內部類VERSION，版本字串

public static class VERSION {
public static final String BASE_OS = null;
public static final String CODENAME = null;
public static final String INCREMENTAL = null;
public static final int PREVIEW_SDK_INT = 0;
public static final String RELEASE = null;//系統版本
public static final String SDK = null;//SDK版本
public static final int SDK_INT = 0;
public static final String SECURITY_PATCH = null;

public VERSION() {
throw new RuntimeException("Stub!");
}
}

通過Build獲取裝置硬體資訊：

public static final String BOARD = null;//主機板
public static final String BOOTLOADER = null;//系統啟動程式版本號
public static final String BRAND = null;//系統定製商
public static final String CPU_ABI = null;//cpu指令集
public static final String CPU_ABI2 = null; //cpu指令集2
public static final String DEVICE = null;//裝置引數
public static final String DISPLAY = null;//顯示屏引數
public static final String FINGERPRINT = null;//唯一識別碼
public static final String HARDWARE = null;//硬體名稱
public static final String HOST = null;
public static final String ID = null;//修訂版本列表
public static final String MANUFACTURER = null;//硬體製造商
public static final String MODEL = null;//手機型號，比如xiaomi5，vivox21
public static final String PRODUCT = null;//手機制造商，比如Huawei
public static final String RADIO = null;//無線電韌體版本
public static final String SERIAL = null;硬體序列號
public static final String[] SUPPORTED_32_BIT_ABIS = null;//32位cpu指令集
public static final String[] SUPPORTED_64_BIT_ABIS = null;//64位cpu指令集
public static final String[] SUPPORTED_ABIS = null;
public static final String TAGS = null;//描述Build的標籤
public static final long TIME = 0L;
public static final String TYPE = null;//build的型別
public static final String UNKNOWN = "unknown";
public static final String USER = null;
