并确保您的目录或文件夹在服务器是可执行的，可写的和可读的。我有这个作为主要问题。这是所谓的777权限。相信我，这是一样重要的其他事情要考虑。

使用MultipartEntity将多个图像发送到服务器相当困难。我搜索了这个，但没有找到任何正确的解决方案，然后我用自己的方法将多个图像发送到服务器*，这里我将所选路径的数组发送到asynctask，在asynctask中我将图像发送到服务器 *
**正在调用Asysnctask函数-**new Upload_Multiple.excute（路径数组[]））

Private class Upload_Multiple_img extends AsyncTask<String, Void, String> {

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();

    }

    protected String doInBackground(String... paths_array) {


        String data = "";

        for (int i = 0; i < paths_array.length; i++) {

            //  get_Picture_bitmap() returns bitmap by passing path of image 
             //   get_Picture_bitmap() is mentioned below. 
            Bitmap bitmap = get_Picture_bitmap(paths_array[i]);

            ByteArrayOutputStream stream = new ByteArrayOutputStream();

            bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
            InputStream in = new ByteArrayInputStream(stream.toByteArray()); // convert

            DefaultHttpClient httpclient = new DefaultHttpClient();

            String server_funtion_url="...serveraddres"+funtion_at_server"";
            HttpPost httppost = new HttpPost(server_funtion_url); // server

            MultipartEntity reqEntity = new MultipartEntity();

            obj_SP = ImagePicker.this.getSharedPreferences("Eperty", 0);

            String id_prop = obj_SP.getString("new_prop_id", "");

            String Image_Name =
                    + String.valueOf(System.currentTimeMillis()) + ".jpg";
// image is a key which is used at server end to get this 
            reqEntity.addPart("image", Image_Name, in);

            httppost.setEntity(reqEntity);

            HttpResponse response = null;
            try {
                response = httpclient.execute(httppost);
                data = EntityUtils.toString(response.getEntity());
                System.out.println("FFFF== " + data);

            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();

            }

        }

        return data;
    }

    @Override
    protected void onProgressUpdate(Void... values) {

        super.onProgressUpdate(values);
    }

    @Override
    protected void onPostExecute(String result) {

        ConstantData.ToastAlert(ImagePicker.this,
                "Images Uploaded successfully");

    }
}

• 用于压缩图像和获取位图，我制作了以下函数 *

public Bitmap get_Picture_bitmap(String imagePath) {

long size_file = getFileSize(new File(imagePath));

size_file = (size_file) / 1000;// in Kb now
int ample_size = 1;

if (size_file <= 250) {

    System.out.println("SSSSS1111= " + size_file);
    ample_size = 2;

} else if (size_file > 251 && size_file < 1500) {

    System.out.println("SSSSS2222= " + size_file);
    ample_size = 4;

} else if (size_file >= 1500 && size_file < 3000) {

    System.out.println("SSSSS3333= " + size_file);
    ample_size = 8;

} else if (size_file >= 3000 && size_file <= 4500) {

    System.out.println("SSSSS4444= " + size_file);
    ample_size = 12;

} else if (size_file >= 4500) {

    System.out.println("SSSSS4444= " + size_file);
    ample_size = 16;
}

Bitmap bitmap = null;

BitmapFactory.Options bitoption = new BitmapFactory.Options();
bitoption.inSampleSize = ample_size;

Bitmap bitmapPhoto = BitmapFactory.decodeFile(imagePath, bitoption);

ExifInterface exif = null;
try {
    exif = new ExifInterface(imagePath);
} catch (IOException e) {
    // Auto-generated catch block
    e.printStackTrace();
}
int orientation = exif
        .getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
Matrix matrix = new Matrix();

if ((orientation == 3)) {
    matrix.postRotate(180);
    bitmap = Bitmap.createBitmap(bitmapPhoto, 0, 0,
            bitmapPhoto.getWidth(), bitmapPhoto.getHeight(), matrix,
            true);

} else if (orientation == 6) {
    matrix.postRotate(90);
    bitmap = Bitmap.createBitmap(bitmapPhoto, 0, 0,
            bitmapPhoto.getWidth(), bitmapPhoto.getHeight(), matrix,
            true);

} else if (orientation == 8) {
    matrix.postRotate(270);
    bitmap = Bitmap.createBitmap(bitmapPhoto, 0, 0,
            bitmapPhoto.getWidth(), bitmapPhoto.getHeight(), matrix,
            true);

} else {
    matrix.postRotate(0);
    bitmap = Bitmap.createBitmap(bitmapPhoto, 0, 0,
            bitmapPhoto.getWidth(), bitmapPhoto.getHeight(), matrix,
            true);

}

return bitmap;

• 服务器端代码 *

$target_dir = "../webadmin/user_image/";
$target_dir = $target_dir . basename($_FILES["user_img"]["name"]);
if(move_uploaded_file($_FILES["image"]["tmp_name"], $target_dir))
  {
     $msg = "The file ". basename($result[0]). " has been uploaded.";
     $send_arr['success'] = 1;
     $send_arr['message'] = $msg;
     echo json_encode($send_arr);
  }
else 
  {
     $msg = "Sorry, there was an error uploading your file.";
     $send_arr['success'] = 0;
     $send_arr['message'] = $msg;
     echo json_encode($send_arr);
  }

为什么你不能只是创建数组的json对象的图像base64和张贴到服务器和在您的服务器api读取这些图像转换为字节和使用作为图像.检查我的answe和尝试实现.在Android如何张贴数据到webservice这是在WCF中创建？
你从照相机得到的图像存储在sd卡的uri中，然后读取它们。你可以指定图像名称sequntialy。然后从uri中读取它们。

尝试在WAMP服务器中增加php.ini文件的post_max_size

请找到下面的方法...在这里我用AQUERY发送多个图像文件。最好的库来执行所有后台网络相关的任务。（像 AJAX ）。
https://code.google.com/p/android-query/

public void uploadImageFile( String filePath,
            String message) {

        Context context = ApplicationContextProvider.getContext();
        String url = SERVER_URL + "/user/uploadImageFile";

            try {
                Toast.makeText(context, "Uploading...", Toast.LENGTH_SHORT)
                        .show();

                String compressedFile = CommonUtilities.compressImage(filePath,
                        context);

                Map<String, Object> params = new HashMap<String, Object>();

                File imageFile = new File(compressedFile);
                byte[] imageBytes1 = FileUtils.readFileToByteArray(imageFile);
                params.put("imageBytes", imageBytes1);
                params.put("message",URLEncoder.encode(message, "UTF-8"));

                AQuery aq = new AQuery(context);
                aq.ajax(url, params, JSONObject.class,
                        new AjaxCallback<JSONObject>() {
                            @Override
                            public void callback(String url, JSONObject json,
                                    AjaxStatus status) {
                                Toast.makeText(
                                        ApplicationContextProvider.getContext(),
                                        "Uploaded successfully",
                                        Toast.LENGTH_SHORT).show();


                            }
                        });
            } catch (Exception e) {
                e.printStackTrace();
                Toast.makeText(context, e.getMessage(), Toast.LENGTH_SHORT)
                        .show();
            }

    }
