无法在android studio中解析JSON响应

Question

我正在尝试构建一个简单的天气应用程序。我正在使用forecast.io，只是尝试提取汇总，温度和降水。到目前为止，我已经能够从网站获得响应，但我无法解析它并只记录我上面提到的三个值。这是我的logCat响应：

这是我的mainActivity代码：

package sidd.tisb.lms.sidsstudios.weather;

import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class MainActivity extends Activity {
    String url = ("https://api.forecast.io/forecast/fee692c335fd7e561223c520322731e1/37.329586,-122.027337");
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new getWeather().execute();
    }

    class getWeather extends AsyncTask<String, String,String>{

        @Override
        protected String doInBackground(String... strings) {
            JsonGetter jsonGetter = new JsonGetter();
            String response = jsonGetter.getJSON(url);
            try {
                JSONArray jsonArray = new JSONArray(response);
                for (int i = 0; i<jsonArray.length();i++){
                    JSONObject jsonObject = jsonArray.getJSONObject(i);
                    String summary = jsonObject.getString("summary");
                    String temperature = jsonObject.getString("temperature");
                    String rainProb = jsonObject.getString("precipProbability");
                    Log.e("Summary: ", summary );
                    Log.e("Temperature: ",temperature);
                    Log.e("Probability of rain: ", rainProb);
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
            return null;
        }
    }
}

我知道我还没有从strings.xml中提取URL字符串或者使用URLConnection，但这只是一个测试，我不知道为什么JSON没有被解析。 这是我的JSONGEtter类：

package sidd.tisb.lms.sidsstudios.weather;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
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.EntityUtils;

import java.io.IOException;

/**

 */
public class JsonGetter {

    String response;

    public String getJSON(String URL) {
        try {
            HttpGet httpGet = new HttpGet(URL);
            HttpClient httpClient = new DefaultHttpClient();
            HttpResponse httpResponse = httpClient.execute(httpGet);
            HttpEntity httpEntity = httpResponse.getEntity();
            response = EntityUtils.toString(httpEntity);
        } catch (IOException e) {
            e.printStackTrace();
        } {

        }
        return response;
    }
}

关于为什么我没有得到显示摘要，温度和降水的日志语句的任何想法？ 感谢!!!
