title: Retrofit 2 - URL Query Parameter
body: <p>I am using a query parameters to set the values needed by the Google Maps API.</p>
  
  <p>The issue is I do not need the <code>&amp;</code> sign for the first query parameter.</p>
  
  <pre><code>@GET("/maps/api/geocode/json?")
      Call&lt;JsonObject&gt; getLocationInfo(@Query("address") String zipCode,
                                               @Query("sensor") boolean sensor,
                                               @Query("client") String client,
                                               @Query("signature") String signature);
  </code></pre>
  
  <p>Retrofit generates: </p>
  
  <pre><code>&amp;address=90210&amp;sensor=false&amp;client=gme-client&amp;signature=signkey
  </code></pre>
  
  <p>which causes the call the fail when I need it to be</p>
  
  <pre><code>address=90210&amp;sensor=false&amp;client=gme-client&amp;signature=signkey
  </code></pre>
  
  <p>How do I fix this?</p>
