copied!<h1>UPDATE</h1> <p>This is a very old answer. I definitely won't recommend Apache's client anymore. Instead use either: </p> <ul> <li><a href="http://square.github.io/okhttp/" rel="noreferrer">OkHttp</a></li> <li><a href="http://developer.android.com/reference/java/net/HttpURLConnection.html" rel="noreferrer">HttpUrlConnection</a></li> </ul> <h1>Original Answer</h1> <p>First of all, request a permission to access network, add following to your manifest:</p> <pre><code><uses-permission android:name="android.permission.INTERNET" /> </code></pre> <p>Then the easiest way is to use Apache http client bundled with Android:</p> <pre><code> HttpClient httpclient = new DefaultHttpClient(); HttpResponse response = httpclient.execute(new HttpGet(URL)); StatusLine statusLine = response.getStatusLine(); if(statusLine.getStatusCode() == HttpStatus.SC_OK){ ByteArrayOutputStream out = new ByteArrayOutputStream(); response.getEntity().writeTo(out); String responseString = out.toString(); out.close(); //..more logic } else{ //Closes the connection. response.getEntity().getContent().close(); throw new IOException(statusLine.getReasonPhrase()); } </code></pre> <p>If you want it to run on separate thread I'd recommend extending AsyncTask:</p> <pre><code>class RequestTask extends AsyncTask<String, String, String>{ @Override protected String doInBackground(String... uri) { HttpClient httpclient = new DefaultHttpClient(); HttpResponse response; String responseString = null; try { response = httpclient.execute(new HttpGet(uri[0])); StatusLine statusLine = response.getStatusLine(); if(statusLine.getStatusCode() == HttpStatus.SC_OK){ ByteArrayOutputStream out = new ByteArrayOutputStream(); response.getEntity().writeTo(out); responseString = out.toString(); out.close(); } else{ //Closes the connection. response.getEntity().getContent().close(); throw new IOException(statusLine.getReasonPhrase()); } } catch (ClientProtocolException e) { //TODO Handle problems.. } catch (IOException e) { //TODO Handle problems.. } return responseString; } @Override protected void onPostExecute(String result) { super.onPostExecute(result); //Do anything with response.. } } </code></pre> <p>You then can make a request by:</p> <pre><code> new RequestTask().execute("http://stackoverflow.com"); </code></pre>
