如何识别小米设备/MIUI系统

您在开发应用的过程中，可能针对小米手机/MIUI设备的用户有一些特殊的设计，本文档提供了如何识别设备、系统版本和浏览器UA的方法

如何检测小米设备：

请使用android.os.Build对象，查询MANUFACTURER和MODEL的值，MANUFACTURER值为Xiaomi即为小米设备

如何检测MIUI V5：

查询property: ro.miui.ui.version.name ，值是”V5″ 就是MIUI V5系统；值是”V6″就是MIUI 6系统。

User-Agent：
如果您从事WebApp开发， 可能需要识别浏览器，下面描述了MIUI浏览器的User-Agent

: 系统版本号，如: 4.1.1

: 系统的国家地区，如: 中国大陆是zh-cn

: 设备型号，如: MI2

: 产品线，如: 小米手机2是JRO03L
Mozilla/5.0 (Linux; U; Android ; ; Build/) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30 XiaoMi/MiuiBrowser/1.0

        Properties prop = new Properties();
        boolean isMIUI;
        try {
            prop.load(new FileInputStream(new File(Environment.getRootDirectory(), "build.prop")));
        } catch (IOException e) {
            e.printStackTrace();
            return false;
        }
        isMIUI = prop.getProperty(KEY_MIUI_VERSION_CODE, null) != null
                || prop.getProperty(KEY_MIUI_VERSION_NAME, null) != null
                || prop.getProperty(KEY_MIUI_INTERNAL_STORAGE, null) != null;
        return isMIUI;
    }
