MultipartEntityBuilder将图片发送到铁路服务器

Question

我正在尝试发送MultipartEntityBuilder到我的Rails服务器.但是,当我尝试构建它时崩溃并给我错误

03-25 09:44:50.001 W/System.err? java.util.concurrent.ExecutionException: java.lang.NoSuchMethodError: No static method create(Ljava/lang/String;[Lorg/apache/http/NameValuePair;)Lorg/apache/http/entity/ContentType; in class Lorg/apache/http/entity/ContentType; or its super classes (declaration of 'org.apache.http.entity.ContentType

        HttpPost httpost = new HttpPost(url);
        MultipartEntityBuilder entity = new MultipartEntityBuilder.create();
        entity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        for(int index=0; index < nameValuePairs.size(); index++) { 
            ContentBody cb;
            if(nameValuePairs.get(index).getName().equalsIgnoreCase("File")) { 
                File file = new File(nameValuePairs.get(index).getValue());
                FileBody isb = new FileBody(file);
                entity.addPart(nameValuePairs.get(index).getName(), isb);
            } else { 
                // Normal string data 

                cb =  new StringBody(nameValuePairs.get(index).getValue(),ContentType.TEXT_PLAIN);
                entity.addPart(nameValuePairs.get(index).getName(),cb); 
            } 
        } 
 return entity.build();

这是我正在使用的代码,我仍然在构建MultipartEntity时遇到错误,它会说错误.

尝试使用httpmime版本4.3.6

我尝试使用4.4+但总是同样的问题.
