将图片从Android中的URL保存到特定位置

public class ImageDownloader {

        try {
            // 创建URL对象

            connection.connect();

            // 获取输入流
            InputStream inputStream = connection.getInputStream();

            // 创建文件输出流
            File file = new File(savePath);
            FileOutputStream outputStream = new FileOutputStream(file);

            // 读取输入流并写入输出流
