Perhaps your base64 encoded data doesn't contain line breaks, or contains too few of them?
Causing the readline() to try and read the entire 5 MB (or a large portion of it) in memory? For email content (since you mentioned K9) it's common to line-wrap base64 data at some reasonable line size, like 76 characters (you know, many people still use DOS, even in this day and age). The same principle could apply to web data. Besides, line breaks do not have any significance for base64 encoded data (unlike, e.g. quoted-printable, or format-flowed text/plain), so you could just ignore the line structure. I'm sure there is piece of code somewhere in K9 sources that can decode base64 data on the fly without excessive buffering. There is also this: http://developer.android.com/reference/android/util/Base64InputStream.html ... which is part of Android starting with API 8, but hey, the sources are only a few clicks away. -- K 4 апреля 2012 г. 22:27 пользователь FractalBob <[email protected]> написал: > > > On Apr 4, 8:48 am, TreKing <[email protected]> wrote: > > On Wed, Apr 4, 2012 at 10:38 AM, FractalBob <[email protected]> wrote: > > > The data, a kind of mail attachment, is a music file > > > > Why are you reading lines from this data then? > > > The data is coming in Base 64 encoded from the Web app and then passed > directly to the processing application.
