title: Supporting android devices with phone and without phone capabilities
body: <p>I have an application that will run on devices that have phone capabilities and that don't. Here are some of my queries:</p>
  
  <p>1) Will i be able to support both type of devices.
  2) For the devices that have phone capabilities, i need to enable calling feature. and the device that do not have phone capabilities i will disable calling functionality.</p>
  
  <p>I am not very clear about the &lt;user-permissions&gt; and &lt;user-features&gt; concept, is there a way to specify phone  &lt;user-features&gt;</p>
