android 29及以上高版本获取SD外部存储器目录/storage/emulated/0

     // 获得SD外部存储根目录一般为：/storage/emulated/0
    public static File getSDRootPath(Context context) 
        File sdPath;
        boolean isSDExist = Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED); //SD卡是否存在
        if (isSDExist) 
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) 
                File externalFileRootDir = context.getExternalFilesDir("");
                do 
                    externalFileRootDir = Objects.requireNonNull(externalFileRootDir).getParentFile();
                 while (Objects.requireNonNull(externalFileRootDir).getAbsolutePath().contains("/Android"));
                sdPath = Objects.requireNonNull(externalFileRootDir);
             else 
                sdPath = context.getExternalFilesDir("");
            
         else 
            sdPath = Environment.getRootDirectory();//根目录
        

        return sdPath;
