일단 소스는..
bHome.setOnClickListener(new Button.OnClickListener() {
            @Override
            public void onClick(View v) {
                intent = new Intent(ListSub.this, Main.class);
                startActivity(intent.setFlags(intent.FLAG_ACTIVITY_SINGLE_TOP));
                }
            });
이런 간단한 버튼 소스 인데요....
요놈이 계속 애러를 먹네요 ......
대충 디버깅 해서 찾았는데 애러 날게 없는데 말이죠...
