Php 在android服务器上上传db文件

我正在从我的应用程序数据目录上载db文件。服务器总是返回错误消息。我不知道原因。请帮帮我

以下是我的android代码：

  String URL="http://hazelrink.com/apps/Sandbox/upload1.php";

     String databasePath = getActivity().getApplicationContext().getDatabasePath("4C1A_14.db").getPath();
        File f = new File(databasePath);


    HttpClient c = new DefaultHttpClient();

    HttpPost p = new HttpPost(URL);

        try {
            InputStreamEntity reqEntity = new InputStreamEntity(
                    new FileInputStream(f), -1);

             reqEntity.setContentType("multipart/form-data");

            reqEntity.setChunked(true); // 
          ResponseHandler<String> responseHandler = new BasicResponseHandler();
        p.setEntity(reqEntity);

          String r= c.execute(p,responseHandler);
         status = r;
        Log.i("Login", status);

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

您是否已在创建此web服务的位置创建了

4CA1\u BR

此名称文件夹？？？否。我为什么要创建该文件夹？因为基本上这就是.db将要上载的目录。只需在服务器上创建相同名称的文件夹，就在您的web服务所在的位置。我已为此共享了iPhone代码。请确认文件夹是必需的。您的iPhone代码是否正在将文件上载到服务器？

<?php 
$uploaddir = '4CA1_BR/'; 
$file = basename($_FILES['uploadedfile']['name']); 
$uploadfile = $uploaddir . $file;

   echo "SU";
