This project implements a native Android application for Constant Contact email marketing customers. It communicates with Constant Contact via our RESTful web service APIs, documentation for which can be found at developer.constantcontact.com .
It works. Change minimum sdk version in line 65 of AndroidManifest.xml to 4, and the app will scale nicely to newer/larger display Android devices. I edit this, added my API Key, disabled the API Key warning, and built this all in AIDE (free from Google Play - formerly Android Market), right on my Android device, and now it's running. Can't complain.
