Hi,
I have no idea if this is related but I seem to remember from a life long, long
ago that you can set up and FTP connection in two modes ASCII and binary. The
default is (used to be) ASCII and when you feed binary data through that
connection then (some) non-ascii characters were
No never used with images.
//length was "*2" but why?
That is for an buggy ftp-server, which mishandled multibyte encodings. On
UTF-16 Files he has reported the number of chars instead of bytes, so the
file size was just the half erverytime.
fos.write(data);
this should be something like:

The code is used in an AsyncTask and there's more error handling to it
(including proper error messages,...), I just simplified it. ;)
Have you ever tested it with images too? Text files always seem to download
properly (no matter what size), it's just the images that are
Hi everyone!
I created a small test app that uses my "download" class on a button press
(but doesn't do anything else) and did some more testing with it (with
"FTP.BINARY_FILE_TYPE"):
- Downloading a 14mb txt file (and its copies) always finishes with a
complete file (even with a long file name)
The following line is wrong:
while ((len = bis.read(buf)) > 0) { //Same result using only 'is'
read == -1 marks the end of the stream. 0 shows only that the stream is
still waiting for the next chunk of data.
Please read the JavaDocs:

Thanks for your reply!
I changed the code and did the usual AndroidStudio restart/clean/build but most
images are still downloaded incompletely.
I don't know if my other answer (sent about an hour ago) came through (I did
some more testing today), so here's an imgur album with test images and
Hmm maybe it is the bufferdStream.
That's working code I'm using in a project for years now:
private FTPClient createClient()
{
FTPClient ftp = new FTPClient();
FTPClientConfig config = new FTPClientConfig();
config.setServerTimeZoneId("UTC");
If you want to read a stream without dealing with low-level headaches, you
can use

Don't know if the code you have showed is your original one but in
general its not a good idea to "catch and ignore" exceptions, yo either:
- simply buble up to the caller
- wrap into other exceptions if required by the API
- explicitly handle/document
I'm using comons-ftp for large files and
@ julia.ruzicka
content is just a simple POJO holding the byte and meta data (like
timestamps). In some situations I'm using a fileoutputstream after
disconnecting from ftp. I'm downloading large (>300 mb) zip-Files.

At first I tried to do it with a `FileOutputStream` and
`ftpClient.retrieveFile(fileName,fos)` but that's how I noticed the problem. I
then switched to using ` InputStream is =
ftpClient.retrieveFileStream(filename)` and when that didn't work properly
either, I added `
