Android Build類的詳解及簡單實例

Android Build類的詳解及簡單實例

一、類結構：

java.lang.Object
? android.os.Build

二、類概述：從系統屬性中提取設備硬件和版本信息。

三、內部類：

1、Build.VERSION 各種版本字符串

2、Build.VERSION_CODES 目前已知的版本代碼的枚舉類

四、常量：UNKNOWN 當一個版本屬性不知道時所設定的值。其字符串值為 unknown .

五、構造方法： Build ()

六、靜態屬性

1、BOARD 主板：The name of the underlying board, like goldfish.

2、BOOTLOADER 系統啟動程序版本號：The system bootloader version number.

3、BRAND 系統定制商：The consumer-visible brand with which the product/hardware will be associated, if any.

4、CPU_ABI cpu指令集：The name of the instruction set (CPU type + ABI convention) of native code.

5、CPU_ABI2 cpu指令集2：The name of the second instruction set (CPU type + ABI convention) of native code.

6、DEVICE 設備參數：The name of the industrial design.

7、DISPLAY 顯示屏參數：A build ID string meant for displaying to the user

8、FINGERPRINT 唯一識別碼：A string that uniquely identifies this build. Do not attempt to parse this value.

9、HARDWARE 硬件名稱：The name of the hardware (from the kernel command line or /proc).

10、HOST

11、ID 修訂版本列表：Either a changelist number, or a label like M4-rc20.

12、MANUFACTURER 硬件制造商：The manufacturer of the product/hardware.

13、MODEL 版本即最終用戶可見的名稱：The end-user-visible name for the end product.

14、PRODUCT 整個產品的名稱：The name of the overall product.

15、RADIO 無線電固件版本：The radio firmware version number. 在API14后已過時。使用getRadioVersion()代替。

16、SERIAL 硬件序列號：A hardware serial number, if available. Alphanumeric only, case-insensitive.

17、TAGS 描述build的標簽,如未簽名，debug等等。：Comma-separated tags describing the build, like unsigned,debug.

18、TIME

19、TYPE build的類型：The type of build, like user or eng.

20、USER

七、公共方法：

public static String getRadioVersion() 獲取無線電固件版本

八、測試示例：

public static String getDeviceInfo() { 
    StringBuffer sb = new StringBuffer(); 
    sb.append("主板： "+ Build.BOARD+"\n"); 
    sb.append("系統啟動程序版本號： " + Build.BOOTLOADER+"\n"); 
    sb.append("系統定制商：" + Build.BRAND+"\n"); 
    sb.append("cpu指令集： " + Build.CPU_ABI+"\n"); 
    sb.append("cpu指令集2 "+ Build.CPU_ABI2+"\n"); 
    sb.append("設置參數： "+ Build.DEVICE+"\n"); 
    sb.append("顯示屏參數：" + Build.DISPLAY+"\n"); 
    sb.append("無線電固件版本：" + Build.getRadioVersion()+"\n"); 
    sb.append("硬件識別碼：" + Build.FINGERPRINT+"\n"); 
    sb.append("硬件名稱：" + Build.HARDWARE+"\n"); 
    sb.append("HOST: " + Build.HOST+"\n"); 
    sb.append("修訂版本列表：" + Build.ID+"\n"); 
    sb.append("硬件制造商：" + Build.MANUFACTURER+"\n"); 
    sb.append("版本：" + Build.MODEL+"\n"); 
    sb.append("硬件序列號：" + Build.SERIAL+"\n"); 
    sb.append("手機制造商：" + Build.PRODUCT+"\n"); 
    sb.append("描述Build的標簽：" + Build.TAGS+"\n"); 
    sb.append("TIME: " + Build.TIME+"\n"); 
    sb.append("builder類型：" + Build.TYPE+"\n"); 
    sb.append("USER: " + Build.USER+"\n"); 
    return sb.toString(); 
  }
