title: How to detect system information like os or device type
body: <p>The most important things I want to know are the device type, the OS version, if it has a hardware keyboard and maybe the screen resolution. but if you know other useful debug information please add them :)</p>
  
  <p>I found this for the OS version:</p>
  
  <pre><code>string += "OS Version: " + System.getProperty("os.version");
  </code></pre>
  
  <p>How do I get the other properties?</p>
