실행은 되지만 버튼을 누를 때 마다 종료되며 강제 종료됩니다.

 

Answer 1

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void com.example.slt.myapp.MyApplication.addToReqQueue(com.android.volley.Request)' on a null object reference

at com.example.slt.myapp.MainActivity.insert(MainActivity.java:70)

MainActivity의 70번째 라인에서 NullPointerException이 났습니다.

70번째 라인에서 사용하는 객체 중에서 null 인 것이 있는지 확인해 보세요. (브레이크 포인트)

Comments

public RequestQueue getReqQueue() {
        if (mRequestQueue == null) {
            mRequestQueue = Volley.newRequestQueue(getApplicationContext());
        }

        return mRequestQueue;
    }

현재 이런식으로 코딩이 되어있는데 이것도 NULL  이 포함되있는건가요?
