    copied!<p>I'm using <a href="http://developer.android.com/reference/org/apache/http/impl/conn/tsccm/ThreadSafeClientConnManager.html" rel="nofollow noreferrer">ThreadSafeClientConnManager</a> to manage a <em>pool of client connections</em>, because my application has several threads, which are simultaneously connecting to a webserver.</p> <p>Abstract sample code: </p> <pre><code>HttpClient httpClient; ClientConnectionManager conMgr = new ThreadSafeClientConnManager(parameters,schReg); httpclient = new DefaultHttpClient(conMgr, parameters); </code></pre> <p>Now lets say on of this threads is downloading a large file, but then the user of my application is switching to another activity/screen. Therefor the file is needless and I'd like to abort this download connection.</p> <p>In <a href="http://developer.android.com/reference/org/apache/http/impl/conn/tsccm/ThreadSafeClientConnManager.html" rel="nofollow noreferrer">ThreadSafeClientConnManager</a> I found this method:</p> <p><code>public ClientConnectionRequest requestConnection (HttpRoute route, Object state)</code> Returns a new ClientConnectionRequest, from which a ManagedClientConnection can be obtained or the <strong>request can be aborted</strong>.</p> <p>So far I've been using:</p> <pre><code>HttpGet httpRequest = new HttpGet(URL_TO_FILE); HttpResponse response = (HttpResponse) httpclient.execute(httpRequest); [...] </code></pre> <p>Now from what I understand, I've to use:</p> <p><code>httpclient.getConnectionManager().requestConnection(HttpRoute route, Object state);</code></p> <p>And that's the point where I'm stuck. I assume that for the route I can just use <code>new HttpRoute(new HttpHost("10.0.0.1"))</code> or whatever my server is, but what to put in for <code>Object state</code>?</p> <p>And second, as soon as I've the <code>ClientConnectionManager</code> I can call <code>getConnection(long timeout, TimeUnit tunit)</code>. But then from there, how I do I execute my <code>HttpGet httpRequest = new HttpGet(URL_TO_FILE);</code> as I did before with <code>HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);</code>?</p> <p>I've been gone through the documentation and tried out quite a few different things, but I wasn't able to obtain a working solution. Therefor any suggestions and/or code examples are more than welcome.</p>
