com.android.kit 라는 패키지(A)와 com.android.lkw.kit 라는 패키지(B)가 있습니다.  

A어플리케이션에서 인텐트로 B어플리케이션(액티비티) 을 호출하려고 하는데요

                    Intent intent = new Intent();
                   // intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    intent.setComponent(new ComponentName("com.android.lkw.kit", "com.android.lkw.kit.Service"));
                    startActivity(intent);

첨에는 에러없이 됬었는데 제가 뭘 잘못만졋는지는 모르겠으나 계속 에러나네요 ㅠㅠ
