title: How can I allow lower Android API level users to download my app in a higher API level version?
body: <p>I am using <strong>Unity</strong> to build an application and there is a part that I applied <strong>ARCore</strong>. However, ARCore only supports devices which have <strong>API level 27 or above</strong>.</p>
  <p>I want to build a version which can <strong>also apply in the lower API level devices</strong> because AR is <strong>just one part</strong>  in my whole app.</p>
  <p>What I expect the scenario is: not allowing the users which is lower API level 27 to trigger the AR function, but they can <strong>still use</strong> my app.</p>
  <p>I am going to release this app to <strong>Google Play Store</strong>. Do you have any suggestions?</p>
