To add my $0.02 to everything Daniel wrote -- -- why use BufferedHttpEntity?
http://developer.android.com/reference/org/apache/http/entity/BufferedHttpEntity.html
A wrapping entity that buffers it content if necessary. The buffered entity is always repeatable. If the wrapped entity is repeatable itself, calls are passed through. If the wrapped entity is not repeatable, the content is read into a buffer once and provided from there as often as required.
I don't see anything in the posted snippet that would require a repeatable entity (i.e. rewinding the stream and reading the same data again).
The underlying entity is most likely not repeatable, so all this does is forces unnecessary in-memory buffering. Perhaps there is a limit to this buffer?

It is worth examining few things about your entity: - is it streaming? - is it chunked? - get it length.. All of those are method calls on HttpEntity. Also it is worth checking the headers of your request. If the requested file is big, it is most likely that it will get chunked by the web server. In such case, your client will need some extra logic to receive the whole chunked file. I *presume* that chunked response mean that getContentLength() returns the length of each chunk that is ready to be received.
