이것은 "도전 과제"를 만든 모델의 코드입니다. 나에게 그 비트 맵을 말하는이 예외를 던져 것이다

public boolean saveOpenChallenges(List<Challenge> challenges) { 
    FileOutputStream fos = null; 
    ObjectOutputStream out = null; 
    try { 
     File new_file = new File(context.getFilesDir(), CHALLENGES_FILE_NAME); 
     new_file.createNewFile(); 
     fos = new FileOutputStream(new_file); 
     out = new ObjectOutputStream(fos); 
     out.writeObject(challenges); 
     out.close(); 
     Log.d("daim", "saving challenges to file!"); 
     return true; 
    } catch (Exception e) { 
     Log.e("bajs", "" + e.getMessage()); 
     return false; 
    } finally { 
     close(fos); 
    }   
} 

: 모든 문제는 비트 맵 이미지가, 지금은 로컬로 저장하기 위해 파일에 ArrayList를 저장하려면,이 내가 그것을 저장하는 방법입니다 직렬화 또는 뭔가, 비트 맵을 사용하여 이러한 개체를 저장하는 방법을 달성 할 수 있습니까? 정말 고마워요, 답변 :)

방금 ​​대신 이미지를 SD 카드에 저장했습니다.
