Update April 29th 2014:
My answer is kind of old by now and I guess you rather want to use some kind of high level library such as Retrofit.
Based on this blog I came up with the following solution: http://blog.tacticalnuclearstrike.com/2010/01/using-multipartentity-in-android-applications/
You will have to download additional libraries to get MultipartEntity running!
Download httpcomponents-client-4.1.zip from http://james.apache.org/download.cgi#Apache_Mime4J and add apache-mime4j-0.6.1.jar to your project.
Download httpcomponents-client-4.1-bin.zip from http://hc.apache.org/downloads.cgi and add httpclient-4.1.jar, httpcore-4.1.jar and httpmime-4.1.jar to your project.
Use the example code below.
private DefaultHttpClient mHttpClient;
public ServerCommunication() { HttpParams params = new BasicHttpParams(); params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); mHttpClient = new DefaultHttpClient(params); }
public void uploadUserPhoto(File image) {
try { HttpPost httppost = new HttpPost("some url"); MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); multipartEntity.addPart("Title", new StringBody("Title")); multipartEntity.addPart("Nick", new StringBody("Nick")); multipartEntity.addPart("Email", new StringBody("Email")); multipartEntity.addPart("Description", new StringBody(Settings.SHARE.TEXT)); multipartEntity.addPart("Image", new FileBody(image)); httppost.setEntity(multipartEntity); mHttpClient.execute(httppost, new PhotoUploadResponseHandler()); } catch (Exception e) { Log.e(ServerCommunication.class.getName(), e.getLocalizedMessage(), e); }}
private class PhotoUploadResponseHandler implements ResponseHandler {
@Override public Object handleResponse(HttpResponse response) throws ClientProtocolException, IOException { HttpEntity r_entity = response.getEntity(); String responseString = EntityUtils.toString(r_entity); Log.d("UPLOAD", responseString); return null; }}
