title: What is the Minimum SDK and which one should I choose
body: <p>First off, I know very little about android development, I am just getting started.</p>
  
  <p>What is the Minimum SDK choice that you get when creating a project in android studio? Is there a downside to using an older one? And if I follow a tutorial is it essential that I use the same one so I can follow along?</p>
  
  <p>Thanks.</p>
