将数据存储到android中的url数组中

Question

我是android的初学者。我想存储来自网络链接的数据.. 我会给你链接..它只有一个值。

“https://api.thingspeak.com/channels/305276/fields/1/24?api_key=KD5IR14FQW33TM4Y”

我想将链接中的值分配给我的android程序中的变量。我正在尝试但是我没有得到..请帮助我..

这是我试过的代码..

import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
import java.net.*;
import java.io.*;


public class urll {
public static String data(int i) {
    URL oracle = null;
    String a = null; 

    try {
        oracle = new URL("https://api.thingspeak.com/channels/305276/fields/1/24?api_key=KD5IR14FQW33TM4Y");
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
    URLConnection yc = null;
    try {
        yc = oracle.openConnection();
    } catch (IOException e) {
        e.printStackTrace();
    }
    BufferedReader in = null;
    try {
        in = new BufferedReader(new InputStreamReader(
                yc.getInputStream()));
    } catch (IOException e) {
        e.printStackTrace();
    }
    String inputLine;
    try {
        while ((inputLine = in.readLine()) != null){
            a=inputLine;
        }

    } catch (IOException e) {
        e.printStackTrace();
    }
    //      System.out.println(inputLine);
    try {
        in.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

      return a;
   }

 }
