공공 api 사용해서 주차장 정보를 뿌려주는 어플을 개발중인데요

 

어제까지 테스트했을땐 잘됬는데 뭐가 문제인지 갑자기

 

어플이 중지되네요 로그를 아무리 들여다봐도 답이 안나오는데

 

혹시 로그정보보고 뭐가 문제인지 파악할수 있나요? ㅠ

Answer 1

MainActivity 75번째 라인에서 널포인트 익셉션이네요

말씀하신부분 코드가

        GooglePlayServicesUtil.isGooglePlayServicesAvailable(MainActivity.this);
       
       
        my_gps = MyLocation.getMyLocation(MainActivity.this);
        my_location = new LatLng(my_gps[0], my_gps[1]);

이부분인데 원래 잘 됬었거든요 ㅠㅠ 아무리 봐도 무슨 이유인지 잘 모르겠네요

---

GooglePlayServicesUtil.isGooglePlayServicesAvailable(MainActivity.this);
my_gps = MyLocation.getMyLocation(MainActivity.this);
if(my_gps != null) {
      my_location = new LatLng(my_gps[0], my_gps[1]);
}
이렇게 널체크하세요 my_gps가 널일때가있을겁니다.

Answer 2

그쪽 부분 코드가

 

 

GooglePlayServicesUtil.isGooglePlayServicesAvailable(MainActivity.this);

 

 

my_gps = MyLocation.getMyLocation(MainActivity.this);

my_location = new LatLng(my_gps[0], my_gps[1]);

 

이렇게 되는데요 전에는 별문제 없이 잘 돌아갔는데 ㅠㅠ 이거 왜이럴까요
