title: Error inflating class android.fragment.app.FragmentContainerView, can someone tell me what I'm missing
body: <p>I'm working on getting the Google Place API to appear within a CardView.</p>
  
  <p>The particular code I'm looking at is from GitHub, seems to be working for everyone else but I don't understand why it's throwing me an error.</p>
  
  <p>This is the error I am getting:</p>

  <p>The main takeaway is that there is an Error inflating class android.fragment.app.FragmentContainerView and that the issue is at line 50 of the XML.</p>
  
  <p>This is the XML:</p>

  <p>So I guess there is something wrong with the FragmentContainerView? But i'm not getting any errors in the code and nothing is coming up on Google.</p>
  
  <p>I feel like maybe something is outdated rather than outright incorrect but I haven't a clue.</p>
  
  <p>Thanks for any input.</p>
