在服务器上上传多个图像

Question

彻底解决这个问题我试图在服务器上上传多张图片，它会成功上传一条消息照片，但是当检查服务器时没有图像，我应该怎么做才能帮助那些人....

public ProgressDialog dialog;
public MultipartEntity entity;
public ArrayList<String> map = new ArrayList<String>();
Bundle b;
public String file_path_one;
public String file_path_two;
public String file_path_three;

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.upload_images);
    b = getIntent().getExtras();

    if (b != null) {
        ArrayList<String> ImgData = b.getStringArrayList("Images");
        for (int i = 0; i<ImgData.size(); i++) {
            map.add(ImgData.get(i).toString());

        }


    } else {

        Toast.makeText(getApplicationContext(), "No Images Available", Toast.LENGTH_LONG).show();
    }
