PHP로 작성된 API를 통해 데이터베이스의 데이터를 쿼리하는 Android 앱을 작성하고 있습니다. 결과를 JSONArray로받습니다. 어떤 이유를 들어JSONArray를 반환하는 동안 Android 예외가 발생했습니다.
이 앱은 JSONArray를 반환 할 때 충돌 유지 :
protected JSONArray doInBackground(String... urls) {
try {
Log.e("STORES: ", readWSDet());
JSONArray WSDet = new JSONArray(readWSDet());
Log.e("POST: ", WSDet.toString());
return WSDet;
} catch (Exception e) {
this.exception = e;
e.printStackTrace();
Log.e("ERROR:" , this.exception.getMessage());
return null;
}
}
모두 "로그"전화는 동일한 코드를 작동하고
[{"id":"0","stop":"18:00:00","price":"99.95","start":"08:00:00","description":"some description","name":"Test","day":"2014-05-04","availability":"9"}]
의 형태로 적절한 출력을 제공 내 프로젝트 내의 다른 액티비티 : (
디버그 모드에서 모든 단계를 처리하는 앱을 볼 수 있으며 복귀 할 때 catch 절로 점프합니다. 다행히도, 나는 단지 로그에서 예외가 발생하도록 관리하지 않습니다.
어떻게 잘못 될지 감지 할 수있는 힌트가 있습니까?
미리 감사드립니다.
P. 서식 문제를 용서하거나 정보를 누락하는 경우는, 이쪽은 내 첫 번째 질문은 여기하시기 바랍니다)
