title: Android studio 3 not showing Android 2.3 sdk API 10 for a new project altought sdk is installed
body: <p>I need to develop a test application for an old Samsung smartphone that has Android 2.3.6</p>
  
  <p>I'm using Android Studio 3.1 and I've installed needed several old SDK from 2.1 to 2.3.3 including google api (that are showed as obsolete in sdk manager)</p>
  
  <p>The problem is that when I create a new project, in the list where I can choose the SDK the lowest API available is 14; it seems that android studio is not showing me obsolete api and I cannot find where to set that I want to see all installed SDK.</p>
