             httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
             HttpPost httppost = new HttpPost(rest_url);

                String restData = org.json.simple.JSONValue.toJSONString(data);


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

             mpEntity.addPart(METHOD, new StringBody(SET_ENTRY));
             mpEntity.addPart(INPUT_TYPE, new StringBody(JSON));
             mpEntity.addPart(RESPONSE_TYPE, new StringBody(JSON));
             mpEntity.addPart(REST_DATA, new StringBody(restData));

                mpEntity.addPart("name",
                         new StringBody("uploadfile"));

             // Adding file data to http body
             mpEntity.addPart("value", cbFile);

             httppost.setEntity(mpEntity);
             System.out.println("executing request " + httppost.getRequestLine());

             HttpResponse response;


                response = httpclient.execute(httppost);

            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

这是logcat的

推荐答案

我有一个类似的问题，我添加以下的依赖关系解决了这个问题：

I had a similar problem, for me adding the following dependencies solved the problem:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:20.+'
    compile 'org.apache.httpcomponents:httpclient-android:4.3.5.1'
    compile('org.apache.httpcomponents:httpmime:4.3') {
        exclude module: "httpclient"
    }

}
