  <p>class that displays data on the phone (you do not need to pay attention on some Strings, just look at the retrofit part,i;ve made it as simple as i can,

  <p>I am aware that the whole bunch of data is going to a simple label , but it is for testing purposes. Still i can not retrieve anything and i do not get any errors as well. Help would be much appreciated. Thanks!</p>
