여러 파일의 문자열 바이트 표현 저장

Question

단일 HTTP 포스트에서 여러 파일의 문자열 바이트 표현을 포함한 정보의 HTTP 게시물을 수행해야합니다. 바이트 할당 오류가 상당히 많이 발생하고 나중에 서버에 게시 할 때이 정보를 저장하는 더 좋은 방법이 있는지 궁금합니다.

나는 기본적으로 꽤 많은 사진 파일을 촬영했습니다, 나는 형식의 단일 HTTP 포스트 문자열로를 포장하고 있습니다 :

name="string byte representation of picture file"&timestamp="time"&gps="latitude""longitude", 등

위의 링크에서 OutofMemory 문제가 발생하여 저장하여 해결할 수 있습니다. 데이터를 FileOutputStream에 보내고 정보를 청크로 서버에 보냅니다.
