안드로이드 로그 분석 부탁드립니다 ㅜㅜ

로그에 나와있는 250줄에 해당하는 소스는

            if (cctv_no.isEmpty() || lpr_seq.isEmpty()) {
                startActivity(new Intent(this, SplashActivity.class));
                
            }

이것 입니다

 

부탁드립니다

Answer 1

cctv_no 또는 lpr_seq 가 값이 잘못된거 같네요.

isEmpty() 하다가 널참조발생에러 입니다..

if (TextUtils.isEmpty(cctv_no) || TextUtils.isEmpty(lpr_seq))
조건문을 바꾸니 실행되네요 ㅜㅜ 이유는 모르겠습니다

Answer 2

cctv_no.isEmpty() || lpr_seq.isEmpty() 여기 Null있다네요. 확인해보세요.

조건문을 바꾸니 실행되네요 ㅜㅜ 이유는 모르겠습니다

Answer 3

String 변수는 isEmpty()로 가 아닌, == null 이나 TextUtil.isEmpty() 로 체킹하세요.
