Android Apps - Modify/Improve

Introduction: We are looking for developer to develop an android VPN app based on this Open Source project: [login to view URL] . The source code is ready and usable, we just need some extra feature such as login, and servers list (ListView) and allow them to connect, etc. to integrate into the open source apps. We have a production backend API web services that will return JSON data. Source Control: As you develop the apps, you must commit the changes to Git (BitBucket/GitHub) or any other source control.
