title: Should I directly access the FIWARE Orion context broker API in my (android) app?
body: <p>I'm currently developing an (android) app which should access and update data stored in my FIWARE instance and also respond to subscriptions.</p>
  
  <p>Is there a recommended architecture on how I should access the data?
  Should I directly use the Orion NGSIv2 API or should I implement a middleware layer between my app and FIWARE? </p>
