title: Send a String[] array through the request body to a web service, using Retrofit
body: <p>I want to use a web service that accepts a String[] array in the body of the web request.</p>
  
  <pre><code>public void fooWebService(@RequestBody String[] ids)
  </code></pre>
  
  <p>What would be the best way to send the String[] array from my <code>Android</code> client using <code>Retrofit</code>?  I am assuming I would need to use the <code>@Body</code> annotation.</p>
  
  <p>The <code>content-type</code> is <code>application/json</code>.</p>
