title: Communicate with backend as safe as possible
body: <p>I'm about to start the design of an application for Android (and possibly later on iPhone, if I ever get around learning it). In this application I will need to send and retrieve various information to a backend (that me myself also will need to design and code). The information will most likely be in json format.</p>
  
  <p>How would I go about making this data as safely transmitted as possible? Is https the only anser to this? Or are there any other smart solutions to this?</p>
