Using MultipartEntity in Android applications

- By Fredrik
To be able to upload files from an Android application and use the Multipart content type you need to add some additional jar files to your application.
The files needed are apache-mime4j, httpclient, httpcore and httpmime. All are opensource projects built by the Apache foundation.
Download the 4 files and add them to your project then you should be able to use the following code to post strings and files to pages.

HttpClient httpclient = new DefaultHttpClient();

HttpPost httppost = new HttpPost("http://www.tumblr.com/api/write");

try {

  MultipartEntity entity = new MultipartEntity();

  entity.addPart("type", new StringBody("photo"));

  entity.addPart("data", new FileBody(image));

  httppost.setEntity(entity);

  HttpResponse response = httpclient.execute(httppost);

} catch (ClientProtocolException e) {

} catch (IOException e) {

}
