[Android] finish, finishAffinity

1. finish란?

---

    public void finish() {
        finish(DONT_FINISH_TASK_WITH_ACTIVITY);
    }
    
    finish();

해당 Activity를 종료할때 호출한다

이때 startActivityForResult()로 호출했다면 호출한 부모Activity에 대해서는 현재 Activity를 종료함과 동시에 ActivityResult를 onActivityResult()함수를 통해 전달한다.
