액티비티에서 다른 액티비티로 객체정보를 전달하려는데 오류가 납니다...

 

Intent DisplayActivity = new Intent(MainActivity.this,DisplayActivity.class);
DisplayActivity.putExtra("FTPConnector", ftpc);
startActivity(DisplayActivity);

 

대략 이런식으로 되어있고, 받는쪽에는

 

onCreate부분에 이런식으로 선언이 되있습니다.

FTPConnector ftpc = (FTPConnector)getIntent().getExtras().getSerializable("FTPConnector");

 

FTPConnector 라는 객체는 implements로 Serializable 추가 해줬구요...

 

오류 내용은 이렇습니다.

이론상으로는 멀쩡하게 돌아가야 정상인데, 어디서 실수를 한건지.. 아니면 저렇게하면 안된는건지 잘 모르겠네요 ㅠ
