FTA:

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) {
} 

The image variable in this case is a File that contains an image captured by the camera on the phone.
