使用android中的2d Array发送多张图片，通过改造将数据发布到服务器

// 假设有3张图片
Bitmap[] images = new Bitmap[3];
images[0] = BitmapFactory.decodeResource(getResources(), R.drawable.image1);
images[1] = BitmapFactory.decodeResource(getResources(), R.drawable.image2);
images[2] = BitmapFactory.decodeResource(getResources(), R.drawable.image3);

// 定义一个2D字节数组
byte[][] imageBytes = new byte[3][];

// 将每张图片转换为字节数组并存储在2D数组中
for (int i = 0; i < images.length; i++) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    images[i].compress(Bitmap.CompressFormat.PNG, 100, stream);
    imageBytes[i] = stream.toByteArray();
}

// 创建一个HTTP请求
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://your-server-url.com/upload");

// 将2D数组作为请求的主体数据
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
ObjectOutputStream objectOutputStream = new ObjectOutputStream(outputStream);
objectOutputStream.writeObject(imageBytes);
objectOutputStream.flush();
objectOutputStream.close();
ByteArrayEntity entity = new ByteArrayEntity(outputStream.toByteArray());
httpPost.setEntity(entity);

// 发送请求并获取服务器的响应
HttpResponse response = httpClient.execute(httpPost);
