title: Running gradle's connectedAndroidTest on a specific device
body: <p>How do you run <code>connectedAndroidTest</code> on a particular device?</p>
  
  <p>I would expect something like:</p>
  
  <pre><code>./gradlew connectedAndroidTest -DconnectedAndroidTest.device=XXXX
  </code></pre>
  
  <p>We have a number of devices plugged into our CI server and I can't seem to find any documentation on how to target a specific connected device.</p>
  
  <p><code>connectedAndroidTest</code> runs the tests on ALL connected devices currently.</p>
  
  <p>Thanks.</p>
