一、类结构:
java.lang.Object
? android.os.Build
二、类概述:从系统属性中提取设备硬件和版本信息。
三、内部类:
1、Build.VERSION 各种版本字符串
2、Build.VERSION_CODES 目前已知的版本代码的枚举类
四、常量:UNKNOWN 当一个版本属性不知道时所设定的值。其字符串值为 unknown .
五、构造方法: Build ()
六、静态属性
1、BOARD 主板:The name of the underlying board, like goldfish.
2、BOOTLOADER 系统启动程序版本号:The system bootloader version number.
3、BRAND 系统定制商: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 设备参数:The name of the industrial design.
7、DISPLAY 显示屏参数:A build ID string meant for displaying to the user
8、FINGERPRINT 唯一识别码:A string that uniquely identifies this build. Do not attempt to parse this value.
9、HARDWARE 硬件名称:The name of the hardware (from the kernel command line or /proc).
10、HOST
11、ID 修订版本列表: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 版本即最终用户可见的名称:The end-user-visible name for the end product.
14、PRODUCT 整个产品的名称:The name of the overall product.
15、RADIO 无线电固件版本:The radio firmware version number. 在API14后已过时。使用 getRadioVersion()代替。
16、SERIAL 硬件序列号:A hardware serial number, if available. Alphanumeric only, case-insensitive.
17、TAGS 描述build的标签,如未签名,debug等等。:Comma-separated tags describing the build, like unsigned,debug.
18、TIME
19、TYPE build的类型:The type of build, like user or eng.
20、USER
七、公共方法:
public static String getRadioVersion() 获取无线电固件版本
八、测试示例:
package com.home.build;
import android.app.Activity;
import android.os.Build;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView showText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
showText = (TextView) findViewById(R.id.main_tv);
showText.setText(getDeviceInfo());
}
/**
* 获取设备信息
*
* @return
*/
private String getDeviceInfo() {
StringBuffer sb = new StringBuffer();
