   The request mode of post is HttpPost HttpPost = new HttpPost ("Https://upload.api.weibo" + ". Com/2/statuses/upload.json");
   Multipartentity object, requires Httpmime-4.1.1.jar file.
   Multipartentity multipartentity = new multipartentity ();
   Stringbody object, parameter stringbody param = new Stringbody (Oauth.getaccesstoken ());
   Multipartentity.addpart ("Access_token", param);
   Stringbody param1 = new Stringbody (Urlencoder.encode (text));
   Multipartentity.addpart ("status", param1); Filespath is a List<string> object that contains the address for the file that needs to be uploaded (String path:filEspath) {log.i ("------------", Path);
   Filebody object that needs to be uploaded files contentbody file = new Filebody (new file (path));
   Multipartentity.addpart ("Pic", file);
   ///Assign the Multipartentity object to HttpPost httppost.setentity (multipartentity);

   HttpResponse response = null;

   Executes the request and returns the result httpresponse response = Httpclient.execute (HttpPost);
   if (Response.getstatusline (). Getstatuscode () = Looper.prepare ();
   Toast.maketext (Context, "Publish success", Toast.length_short). Show ();
   Looper.loop ();

  } catch (Clientprotocolexception e) {e.printstacktrace ();
  catch (IOException e) {e.printstacktrace ();
 }}.start ();
 }
