안드로이드 도움이 필요합니다 json

웹 서비스에서 특정 데이터를 받기 위해 JSON 문자열을 인코딩하는 데 약간의 도움이 필요합니다. 이미 JSON 문자열을 표준 JSONParsser 클래스에서 볼 수있는 표준 방식으로 포맷하려고했지만 내 JSON 문자열이 유효하지 않아서 이전 질문에서 여기에서 볼 수 있다고 들었습니다. Converting a String to JSONObject 제 코드를 아무에게도 묻지 않습니다. 제 코드를 살펴보고 URL 매개 변수에 오류가 있는지 그리고 JSON 문자열을 인코딩하여 데이터를 수신해야 하는지를 묻는 것입니다. 이 웹 서비스.안드로이드 도움이 필요합니다 json

귀하의 URL :

올바른 URL :

해야합니다 당신은 또한 여기에 오류가 있습니다. Here is an example of the url in action. 그 id는 나에게 오류를 주었기 때문에 아마도 자신의 app id를 얻을 필요가 있음을 주목하라. 예를 들어 Yahoo에서 제공하는 데모 앱 ID를 사용하고있는 것 같습니다.
