如何用Android上的MultipartEntityBuilder替換MultipartEntity？

Question

HttpClient httpclient = new DefaultHttpClient(); 
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); 

HttpPost httppost = new HttpPost("http://192.168.150.101:8080/TDIDP/ServletImagen"); 
File file = new File("C:\\pw\\proyectos\\TDIDP\\a.png"); 

MultipartEntity mpEntity = new MultipartEntity(); 
ContentBody cbFile = new FileBody(file, "image/png"); 
mpEntity.addPart("userfile", cbFile); 

httppost.setEntity(mpEntity); 
System.out.println("executing request " + httppost.getRequestLine()); 
HttpResponse response = httpclient.execute(httppost); 
HttpEntity resEntity = response.getEntity(); 

System.out.println(response.getStatusLine()); 
if (resEntity != null) { 
    System.out.println(EntityUtils.toString(resEntity)); 
} 
if (resEntity != null) { 
    resEntity.consumeContent(); 
} 

httpclient.getConnectionManager().shutdown(); 

我有此代碼發送圖片到Servlet，但問題是，現在MultipartEntitiy沒有可用於Android，因爲它已經過時了，我該如何使用MultiPartEntityBuilder做multipar？

我該如何使用MultiPartEntityBuilder來完成多部分。

HttpClient在sdk 23中不再被支持，如果你使用它，你需要解決很多問題。您必須使用URLConnection 您可以在此鏈接中看到MultipartUtilityhttps://github.com/RecastAI/SDK-Android/blob/master/src/main/java/ai/recast/sdk_android/MultipartUtility.java。
