title: Choosing SDK version to reach maximum number of people
body: <p>I am a complete beginner in Android Development and just downloaded Android SDK to integrate it with Eclipse. </p>
  
  <p>However, I don't know which Android version I should select in SDK Manager to allow a maximum number of people to download and use my app.</p>
  
  <p>Here's a screenshot of the manager that is showing up on my screen.</p>

  Thanks.</p>
