로그화면이구여 ... Error copying database  가 뜨는거 봐서는 이쪽  코드 문제 인것 같아 도움 요청합니다., ㅠㅠ 

private static String DB_PATH = "/sdcard/";

   while((length = myInput.read(buffer))>0)
   {
    myOutput.write(buffer, 0, length);
    total_length+=length;
   }

   myOutput.flush();
   myOutput.close();
   myInput.close();
