Do I have to get the entire zip file into memory before extracting? Should I be concerned how much memory this could require? Is there a better way?
If the binary ZIP file is URL encoded then it is a big mess.
If the binary zip file is present as binary data, then I think you can
change from:
ZipInputStream zis = new ZipInputStream(new
ByteArrayInputStream(EntityUtils.toByteArray(entity)));
to:
ZipInputStream zis = new ZipInputStream(entity.getContent());
(code simplified)
