copied!<p>I'm going to assume that you know the path and filename of the image that you want to upload. Add this string to your <code>NameValuePair</code> using <code>image</code> as the key-name.</p> <p>Sending images can be done using the <a href="http://hc.apache.org/downloads.cgi" rel="noreferrer" title="HttpComponents library">HttpComponents libraries</a>. Download the latest HttpClient (currently <a href="http://apache.cs.uu.nl/dist/httpcomponents/httpclient/binary/httpcomponents-client-4.0.1-bin-with-dependencies.zip" rel="noreferrer" title="HttpClient 4.0.1 - Binary with dependencies">4.0.1</a>) binary with dependencies package and copy <code>apache-mime4j-0.6.jar</code> and <code>httpmime-4.0.1.jar</code> to your project and add them to your Java build path.</p> <p>You will need to add the following imports to your class.</p> <pre><code>import org.apache.http.entity.mime.HttpMultipartMode; import org.apache.http.entity.mime.MultipartEntity; import org.apache.http.entity.mime.content.FileBody; import org.apache.http.entity.mime.content.StringBody; </code></pre> <p>Now you can create a <code>MultipartEntity</code> to attach an image to your POST request. The following code shows an example of how to do this:</p> <pre><code>public void post(String url, List<NameValuePair> nameValuePairs) { HttpClient httpClient = new DefaultHttpClient(); HttpContext localContext = new BasicHttpContext(); HttpPost httpPost = new HttpPost(url); try { MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); for(int index=0; index < nameValuePairs.size(); index++) { if(nameValuePairs.get(index).getName().equalsIgnoreCase("image")) { // If the key equals to "image", we use FileBody to transfer the data entity.addPart(nameValuePairs.get(index).getName(), new FileBody(new File (nameValuePairs.get(index).getValue()))); } else { // Normal string data entity.addPart(nameValuePairs.get(index).getName(), new StringBody(nameValuePairs.get(index).getValue())); } } httpPost.setEntity(entity); HttpResponse response = httpClient.execute(httpPost, localContext); } catch (IOException e) { e.printStackTrace(); } } </code></pre> <p>I hope this helps you a bit in the right direction.</p>
