로그인 부분이구요 json parsing 해서 id pass nick 을 가져와 비교하고 로그인 하는 부분입니다.
php Mysql 로 디비 저장되있고 일단 로그상으론 정상적으로 데이터를 parsing 해줍니다.
근데 아래와 같은 에러가 나고 있고 이유를 찾아보았지만 잘 모르겠습니다.
초보입니다.,,,, 의심스러운건 스레드 도는동안 변수에 값이 저장되지도 않았는데 바로 변수값을읽어와 그런게 아닌가 싶은데 ... 에러부분은
public void checkId() {
try {
JSONArray ja = new JSONArray(checked);
이 부분입니다.
