이런 에러들이 발생하는군요 ㅠㅠ 책보고 독학하느라 어디서문제인지 알수가없네요.. 고수님들 부탁드려요
GetLocation클래스안에는 URL만 딸랑들어있습니다.
package com.example.getweatherinfo;
public class GetLocation {
public static final String URL1 = "http://query.yahooapis.com/v1/public/yql?q=select * from geo.places where text=\"";
public static final String URL2 = "\"&format=xml";
}
이렇게요
