title: Android studio > create new project > Google Play Services Activity: What is this?
body: <p>I'm using Android Studio for the first time, and when I create a new project I get a window which asks me what activity I want to add. One option is a "Google Play Services Activity". </p>
  
  <p>What is it for? What does it do? I hope this isn't a stupid question, it feels like it is, but I can't find an answer. I have done some Android development a while ago so understand Activities and so on.  I am finding information on "Google Play Services" but I don't understand what the Activity does.</p>
  
  <p>Thanks</p>
