无法在 android 中使用异步任务中的 MultipartEntityBuilder 上传视频文件

Question

我正在尝试使用 mime.MultipartEntityBuilder 上传视频文件，但我在 logcat

中收到以下错误

这是我的代码库：

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.util.EntityUtils;
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.content.ContentBody;
import org.apache.http.entity.mime.content.FileBody;

import android.os.AsyncTask;
import android.util.Log;

public class UploadVideoAsync extends AsyncTask<String, String, Object[]> {


    @Override
    protected Object[] doInBackground(String... params) {

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(params[0].toString());
        final File video = new File(params[1].toString());
        //String video = params[1].toString();
        ContentBody  cb = new FileBody(video);
        try{
            MultipartEntityBuilder entityBuilder  = MultipartEntityBuilder.create();
            entityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
            //entityBuilder.addPart("video", cb);
            entityBuilder.addBinaryBody("video", video);
            entityBuilder.addTextBody("sid", params[2].toString());
            HttpEntity entity = entityBuilder.build();
            httppost.setEntity(entity);
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity httpEntity = response.getEntity();

            Log.v("result", EntityUtils.toString(httpEntity));

            return new Object[]{response, new BasicResponseHandler().handleResponse(response)};
        }catch (ClientProtocolException e) {

            e.printStackTrace();
       }
        return new Object[0];

    }


}

我找不到确切的问题。有人可以告诉代码有什么问题吗？

好的，这个问题解决了：

Project -> Properties -> Java Build Path -> Order and Export -> Check the jar files -> OK

这是截图：
