title: Checkout from Git only sub folder that contains android application as new project in using Android Studio
body: <p>I have a existing git repository with structure as follows:</p>
  
  <pre><code>Mobile_Application
  -android-app
  -ios-app
  -paying-services
  </code></pre>
  
  <p>I want to check out as new project in my Android Studio version 3.0.1, only what contains in <code>android-app</code> folder. I tried to checkout whole project and I pulled the content of the all folders but could not build the android project at all.
  Is it possible to checkout as new project only the <code>android-app</code> folder?</p>
