내가 여기에있는 Online Tool가 디코딩하지만 코드 내가 여기에 사용 : 예를 들어 는 내가 서버에서 다음 문자열을 가지고

byte[] imageAsBytes = Base64.decode(imageString.getBytes(), Base64.DEFAULT); 

Bitmap bitmap = BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length);

오류를 생성합니다

02-02 19:16:56.460: E/AndroidRuntime(18237): java.lang.IllegalArgumentException: bad base-64

그래서 어디에 문제가 있습니까? 나는 그것이 유효한 Base64로 인코딩 된 문자열이 될 것 같아 만약 링크를 온라인 도구는 또한 wouldnt 그것을 해독 할 수 제공했다.

The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.

을하지만 어디를 말하는 아니에요 :

편집

는 말하고 다른 Online Tool을 발견했다. 패딩 '='을 삭제했지만 변경되지 않았습니다.

이미지를 올바르게 인코딩 했습니까? 귀하의 디코딩 기법이 정확하기 때문입니다. 이제는 이미지 데이터가 문제가 될 수있는 유일한 부분입니다 – MDMalik

내 게시물을 업데이트했습니다. 다른 온라인 도구는 유효하지 않다고 말합니다. – Mulgard

이미지의 인코딩 코드를 게시 할 수 있습니까? 나는 그것이 우리가 문제를 해결하는 데 도움이 될 것이라고 믿습니다. 게다가 웹에서 이미지를 다운로드하거나 모바일에서 이미지를 보려고하십니까? – MDMalik

이것이 올바른 해결책인지는 모르겠지만, 제 경우에는 위의 응답에서 data:image\/jpg; base64,까지 시작 부분을 제거했으며 저에게 도움이되었습니다. 이것은 인코딩 된 데이터의 일부가 아닌 데이터입니다.
