안녕하세요.
오랜만에 앱을 수정할 일이 생겨서 수정하여 테스트를 하였는데 아래와 같은 오류가 납니다.
이유가 뭘까요?
SDK 버전은 1.1.31 입니다.
[SampleLoginActivity]
@Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
KakaoSDK.init(new KakaoSDKAdapter()); <------ 여기서 NULL Pointer 오류
callback = new SessionCallback();
Session.getCurrentSession().addCallback(callback);
if (!Session.getCurrentSession().checkAndImplicitOpen()) {
setContentView(R.layout.layout_common_kakao_login);
}
}
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.app.Application.registerActivityLifecycleCallbacks(android.app.Application$ActivityLifecycleCallbacks)' on a null object reference
