android - 我无法在 android 11 上创建文件夹或共享图像

Question

如何在 android 11 上创建文件夹或共享图像？这是保存文件或图像的第一个代码：

     @Override
        protected String doInBackground(String... args) {
            // TODO Auto-generated method stub
            path = args[0];
            String idStr = path.substring (path.lastIndexOf ('/') + 1);
            File filepath = Environment.getExternalStorageDirectory ();
            File dir = new File (filepath.getAbsolutePath () + "/MyDownloads/");
            dir.mkdirs ();
            String fileName = idStr;
            Ion.with (getApplicationContext ()).load (path)
                    .write (new File (dir, fileName));

            return null;
        }

这是第二个分享：

 @Override
        protected String doInBackground(String... args) {
            // TODO Auto-generated method stub
            path = args[0];
            String idStr = path.substring (path.lastIndexOf ('/') + 1);
            File filepath = Environment.getExternalStorageDirectory ();
            File dir = new File (filepath.getAbsolutePath () + "/MyDownloads/");
            dir.mkdirs ();
            String fileName = idStr;
            file = new File (dir, fileName);
            Ion.with (getApplicationContext ()).load (path)
                    .write (file);
            return null;
        }

请我等待你的帮助。
