Question

我正在尝试使用android工作室在goolge和一些开源的帮助下实现一个有用的旅行计划应用程序

我有没有gradle.build的android应用程序。当它试图运行它我得到错误。

 Error:(20, 28) java: package org.apache.http.util does not exist

以下是出现错误的代码部分。

如何解决错误？

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.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.ByteArrayBuffer;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

    public static String queryUrl(String url) {
    HttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet(url);
    HttpResponse response;

    try {
        response = httpclient.execute(httpget);
        Log.i(TAG, "Url:" + url + "");
        Log.i(TAG, "Status:[" + response.getStatusLine().toString() + "]");
        HttpEntity entity = response.getEntity();

        if (entity != null) {
        InputStream instream = entity.getContent();

        BufferedReader r = new BufferedReader(new InputStreamReader(instream));
        StringBuilder total = new StringBuilder();
        String line;
        while ((line = r.readLine()) != null) {
            total.append(line);
        }

        instream.close();

        String result = total.toString();
        return result;
        }
    } catch (ClientProtocolException e) {
        Log.e(TAG, "There was a protocol based error", e);
    } catch (Exception e) {
        Log.e(TAG, "There was some error", e);
    }

    return null;
    }

请参阅以下答案HttpClient won't import in Android Studio

我不知道你的模块的build.gradle是怎么样的，但是我认为你的apache库有些错误。

另外，我不建议在新的Android应用程序中使用apache HTTP库。请查看OkHttp或Volley

我会在评论中发帖，但我还没有足够的声誉。

包org.apache.http.util不存在
