Android:“Unexpected end of stream” exception downloading large files

I'm downloding a file of approx. 5MB using HttpURLConnection but half way during the downlod i get an "unexpected end of stream" error at this line of my code:

                     while ((count = input.read(data)) > 0) {

Here is the LOG:

Help !!1

EDIT: more info on the code setting up the inputstream:

    HttpURLConnection conexion = (HttpURLConnection)url.openConnection();
                        conexion.setRequestMethod("GET");
                        conexion.setReadTimeout(20000);
                        conexion.connect();
                        File file = new File(root.getAbsolutePath()+"/", fileName);

                             int lenghtOfFile = conexion.getContentLength();

                             InputStream input = new BufferedInputStream(url.openStream());

                             OutputStream output = new FileOutputStream(file);

                             byte data[] = new byte[8192];
...........................

EDIT 2: Got a new error IndexOutOfBoundsException on 25% of download on the following line:

  output.write(data, 0, count);

EDIT 3: I traced the error back to FixedLengthInputStream class and then further back to AbstractHttpInputStream class in where there is this method:

/**
             * Calls abort on the cache entry and disconnects the socket. This
             * should be invoked when the connection is closed unexpectedly to
             * invalidate the cache entry and to prevent the HTTP connection from
             * being reused. HTTP messages are sent in serial so whenever a message
             * cannot be read to completion, subsequent messages cannot be read
             * either and the connection must be discarded.
             *
             * <p>An earlier implementation skipped the remaining bytes, but this
             * requires that the entire transfer be completed. If the intention was
             * to cancel the transfer, closing the connection is the only solution.
             */
            protected final void unexpectedEndOfInput() {
                if (cacheRequest != null) {
                    cacheRequest.abort();
                }
                httpURLConnection.releaseSocket(false);
            }

So it seems that in the case of an Http message error the whole download stream is canceled.

That exception is thrown by FixedLengthInputStream when the expected number of bytes (usually set in the content-length header of the response) is larger than the actual data in the response. Check that the content-length header is correct. (If you're supplying your own value for the content length, make sure it is correct.)

It would help to see your code that sets up the input stream.
