title: GSON pretty priniting doesn't support indentation?
body: <p>Taken from javadoc of GSON.setPrettyPrinting :
  "Configures Gson to output Json that fits in a page for pretty printing."</p>
  
  <p>Ok, fitting to a page is nice. But I want it to be human readable.</p>
  
  <p>and instead: </p>
  
  <pre><code>{"key":"smartphones","solutions":[{"id":"0 ","name":"LG Nexus"}]}
  </code></pre>
  
  <p>have:</p>
  
  <pre><code>{
  "key" : "smartphones",
  "solutions" : [{
          "id" : "0 ",
          "name" : "LG Nexus 5"
          }]
  }
  </code></pre>
  
  <p><strong>--UPDATE --</strong></p>
  
  <p>PrettyPrinting works as expected for latest version (2.2.4).
  Unfortunately, the code I used to test the question was of version 1.4, which I have to use :(</p>
