拒绝连接到Apache服务器

我知道在Stackoverflow上有类似的问题，但他们没有解决我的问题。我想从android上传一个文件到本地的apache服务器，但是获得了'连接被拒绝'的错误。拒绝连接到Apache服务器

我在Mac OS X Lion（Port 80上的Apache）上使用带有Android 3.2和MAMP的物理设备。我还向清单添加了INTERNET权限。

下面是代码：

String lineEnd = "\r\n"; 
    String twoHyphens = "--"; 
    String boundary = "*****"; 

    FileInputStream fileInputStream = null; 
    try { 
     fileInputStream = new FileInputStream(new File(
       "/mnt/sdcard/somefile.xml")); 
    } catch (FileNotFoundException e) { 
     ... 
    } 

    URL url = null; 
    try { 
     url = new URL("http://192.168.x.xxx:80/index.php"); 
    } catch (MalformedURLException e) { 
     ... 
    } 

    try { 
     // Open a HTTP connection to the URL 
     HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 

     // Allow Inputs 
     conn.setDoInput(true); 
     // Allow Outputs 
     conn.setDoOutput(true); 

     // Don't use a cached copy. 
     conn.setUseCaches(false); 

     // Use a post method. 
     conn.setRequestMethod("POST"); 

     conn.setRequestProperty("Connection", "Keep-Alive"); 

     conn.setRequestProperty("Content-Type", 
       "multipart/form-data;boundary=" + boundary); 

     DataOutputStream dos = new DataOutputStream(conn.getOutputStream()); 

     dos.writeBytes(twoHyphens + boundary + lineEnd); 
     dos.writeBytes("Content-Disposition: post-data; name=uploadedfile;filename=" 
       + SOMEFILE + "" + lineEnd); 
     dos.writeBytes(lineEnd); 

     // create a buffer of maximum size 
     int bytesAvailable = fileInputStream.available(); 
     int maxBufferSize = 1000; 
     // int bufferSize = Math.min(bytesAvailable, maxBufferSize); 
     byte[] buffer = new byte[bytesAvailable]; 

     // read file and write it into form... 
     int bytesRead = fileInputStream.read(buffer, 0, bytesAvailable); 

     while (bytesRead > 0) { 
      dos.write(buffer, 0, bytesAvailable); 
      bytesAvailable = fileInputStream.available(); 
      bytesAvailable = Math.min(bytesAvailable, maxBufferSize); 
      bytesRead = fileInputStream.read(buffer, 0, bytesAvailable); 
     } 

     // send multipart form data necesssary after file data... 
     dos.writeBytes(lineEnd); 
     dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 

     // close streams 
     fileInputStream.close(); 
     dos.flush(); 
     dos.close(); 
    } catch (IOException e) { 
     ... 
    }

例外：

server 'http://192.168.x.xxx:80/index.php'
