本文介绍如何在Android应用中使用Multipart内容类型上传文件。通过引入Apache开源库，包括apache-mime4j, httpclient, httpcore及httpmime，实现图片等文件的上传功能。

To be able to upload files from an Android application and use the Multipart content type you need to add some additional jar files to your application.

The files needed are apache-mime4j, httpclient, httpcore and httpmime. All are opensource projects built by the Apache foundation.

Download the 4 files and add them to your project then you should be able to use the following code to post strings and files to pages.

 
        HttpClient httpclient = 
        new 
         DefaultHttpClient();
       
        HttpPost httppost = 
        new 
         HttpPost(
        "http://www.tumblr.com/api/write"
        );
       
        try 
         {
       
        MultipartEntity entity = 
        new 
         MultipartEntity();
       
        entity.addPart(
        "type"
        , 
        new 
         StringBody(
        "photo"
        ));
       
        entity.addPart(
        "data"
        , 
        new 
         FileBody(image));
       
        httppost.setEntity(entity);
       
        HttpResponse response = httpclient.execute(httppost);
       
        } 
        catch 
         (ClientProtocolException e) {
       
        } 
        catch 
         (IOException e) {
       
        }
