body: <p>I want add <code>Firebase Analytics</code> to my app, but my events doesn't send to firebase console.</p>
  
  <p>Sending event in code:</p>
  
  <pre><code>Bundle params = new Bundle();
  params.putString("name", "screenName");
  mFirebaseAnalytics.logEvent("open_screen", params);
  </code></pre>

  <pre><code>public class AnalyticsManager {
  
  private final String NAME = "name";

          }
      }
  
      return instance;
