Retrofit 2 - URL Query Parameter
<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>
