title: install_referrer intent deprecation
body: <p>I have received email from google:</p>
  
  <blockquote>
    <p>We recently announced that we’ll be deprecating the install_referrer intent broadcast mechanism. Because one or more of your apps uses this intent to track referrals, we wanted to ensure you make the switch before March 1, 2020. After this date, new versions of the Play Store app will no longer broadcast the install_referrer intent after app installs.</p>

  <p>I am not using <code>install_referrer</code> directly, but while browsing merged manifest i discovered that some firebase service named with package name <code>com.google.firebase.measurement</code> use it.</p>
  
  <p>My firebase dependencies updated to latest version.</p>
  
  <p>Should I care about it?</p>
