Android 获取手机信息

可通过获取build.prop

 Properties properties = new Properties();
 properties.load(new FileInputStream(new File(Environment.getRootDirectory(), "build.prop")));

例如：获取判断是否为小米手机：

// 通过name获取 值
properties.getProperty(name, defaultValue);

通过properties.getProperty(KEY_MIUI_VERSION_CODE, null) 的返回值进行判断：

private static final String KEY_MIUI_VERSION_CODE     = "ro.miui.ui.version.code";
private static final String KEY_MIUI_VERSION_NAME     = "ro.miui.ui.version.name";
private static final String KEY_MIUI_INTERNAL_STORAGE = "ro.miui.internal.storage";

也可以通过：Build.MANUFACTURER  和 Build.MODEL 一起辅助判断

String[] phones = {"MI 4", "MI 3", "MI 2S"};

try {
    if (Build.MANUFACTURER.toLowerCase().equals("xiaomi")) {
       for (String phone : phones) {
           if (Build.MODEL.contains(phone)) {
                 return true;
           }
       }
    }
} catch (Exception e) {
    e.printStackTrace();
}
