title: ARCore : what is the min SDK version supported ?
body: <p>It is written on this page : </p>
  
  <p><a href="https://developers.google.com/ar/develop/java/getting-started" rel="nofollow noreferrer">https://developers.google.com/ar/develop/java/getting-started</a></p>
  
  <p>that "Your app's minSDKVersion must be 19 or higher" (Android 4.1)</p>
  
  <p>But it is written in the gradle file of the hello_ar_java project this :</p>
  
  <pre><code> // 24 is the minimum since ARCore only works with 24 and higher.
          minSdkVersion 24
  </code></pre>
  
  <p>What is the real min Android version to use ARCore ?</p>
  
  <p>Thanks.</p>
