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

<pre><code>                     while ((count = input.read(data)) &gt; 0) {
</code></pre>

<p>Here is the LOG:</p>

<p>Help !!1</p>

<p>EDIT: more info on the code setting up the inputstream:</p>

<pre><code>    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];

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

<pre><code>  output.write(data, 0, count);
</code></pre>

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

<pre><code>/**
             * 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.
             *
             * &lt;p&gt;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);
            }
</code></pre>

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