title: Connect Android to laptop without Internet connection
body: <p>Say I have a laptop (Windows 10) and an Android phone.  The laptop does not have an internet connection and the Android does not have an internet connection.</p>
  
  <p>I have an Xamarin app that uses a C# Web API that is deployed to the laptop (for testing).  How can I connect the mobile to the laptop without any form of internet connection? I believe I have two options:</p>
  
  <pre><code>1) USB cable
  2) Bluetooth
  </code></pre>
  
  <p>I believe I have to install a wireless hotspot on the laptop and then a reverse tethering on the Android.</p>
  
  <p>Have I understood this correctly? Do I have to do this regardless of whether I use a USB cable or a Bluetooth connection.</p>
