title: Gson custom deserializing logic based on field name
body: <p>My class is like:</p>
  
  <pre><code>class Foo {
     public String duration;
     public String height;
  }
  </code></pre>
  
  <p>And my json data looks like </p>
  
  <pre><code>{"duration":"12200000", "height":"162"}
  </code></pre>
  
  <p>Now I want to deserialize it by </p>
  
  <pre><code> Foo foo = gson.fromJson(jsonStr, Foo.class);
  </code></pre>
  
  <p>So that, 
       foo.duration is "20 mins" (number of minutes),
       foo.height is "162cm" </p>
  
  <p>Is this possible to do using Gson?</p>
  
  <p>Thanks!</p>
