 CN: 此JAR包里面已经集成了android http 网络请求包，也封装了 MultipartEntityBuilder 文件与文字同时上传，实现向下兼容
   你只需要添加这两个包就可以实现android 的多类型网络传输了
    Please add the  packages ：
      compile files(‘libs/org.apache.http.legacy.jar‘)
    compile files(‘libs/httpmime-4.3.5.jar‘)
      compile files(‘libs/android_httpcore_4.3.2.jar‘)//  https://pan.baidu.com/s/1i5mEO53
Inside the JAR package has integrated the android HTTP request packet network, also encapsulates the upload MultipartEntityBuilder file with the text at the same time, achieve backward compatibility  
  /**  example 
     * @param context
     * @param url
     * @param filekey
     * @param params
     * @param file
     * @return 
     */
    public String postMutil(Context context, String url, String filekey, final TreeMap<String, String> params, File file) {
     //  ***省略***
//Image attaching
            MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
            if (file != null && file.exists()) {
                multipartEntity.addBinaryBody(filekey, file, ContentType.MULTIPART_FORM_DATA, file.getName());
            }
//Json string attaching
            for (Map.Entry<String, String> entry : params.entrySet()) {
                multipartEntity.addPart(entry.getKey(), new StringBody(entry.getValue()));
            }
            httppost.setEntity(multipartEntity.build());
     //   ******省略******

    }

compile files(‘libs/android_httpcore_4.3.2.jar‘)//  https://pan.baidu.com/s/1i5mEO53   包已经上传到百度云可以直接下载用
