Build.VERSION类

一、类结构：

java.lang.Object
↳	android.os.Build.VERSION

二、类概述：各种版本字符串

三、构造方法：Build.VERSION()

四、静态属性：

1、CODENAME   当前开发代号：The current development codename, or the string "REL" if this is a release build.

2、INCREMENTAL   源码控制版本号：The internal value used by the underlying source control to represent this build. E.g., a perforce changelist number or a git hash.

3、RELEASE  用户可见的版本字符串：The user-visible version string. E.g., "1.0" or "3.4b5".

4、SDK     SDK版本号：The user-visible SDK version of the framework in its raw String representation; use SDK_INT instead. 在API 4已过时。

5、SDK_INT     SDK版本号：The user-visible SDK version of the framework; its possible values are defined in Build.VERSION_CODES.

五、示例：

	/**
	 * 获取版本信息
	 * 
	 * @return
	 */
	private String getVersionInfo() {
		StringBuffer sb = new StringBuffer();
		sb.append("当前开发代号：" + Build.VERSION.CODENAME);
		sb.append("\n源码控制版本号：" + Build.VERSION.INCREMENTAL);
		sb.append("\n用户可见的版本字符串：" + Build.VERSION.RELEASE);
		sb.append("\nSDK版本号：" + Build.VERSION.SDK);
		sb.append("\nSDK版本号：" + Build.VERSION.SDK_INT);
		return sb.toString();
	}
