File Upload whti Form Data in Android
===

I am working on an Android project that requires uploading files.  Part of the process includes form data, which is sent as a `JSON` string.  This part works fine.

In some cases, images will need to be sent along with the form data.  How can I include image files with the HTTP post.  The number of images may vary depending on the case, and I already have an image manager to store the images as PNGs.  I am using `HttpURLConnection` for testing, but will need to switch to use the `HttpsURLConnection` for production.

Is a URLConnection (or any of its sub classes) the appropriate way to perform file uploads?
