title: where to get certificates for font request?
body: <p>I've been reviewing the official documentation for adding the EmojiCompa library here <a href="https://developer.android.com/guide/topics/ui/look-and-feel/emoji-compat" rel="nofollow noreferrer">https://developer.android.com/guide/topics/ui/look-and-feel/emoji-compat</a> . It has this code:</p>
  
  <pre><code>public class MyApplication extends Application {
    @Override
     public void onCreate() {
       super.onCreate();
       FontRequest fontRequest = new FontRequest(
         "com.example.fontprovider",
         "com.example",
         "emoji compat Font Query",
         CERTIFICATES);
       EmojiCompat.Config config = new FontRequestEmojiCompatConfig(this, fontRequest);
       EmojiCompat.init(config);
     }
  }
  </code></pre>
  
  <p>but it doesn't have any information on where/how to retrieve CERTIFICATES. I checked the font request section and wasn't able to find anything there either.</p>
  
  <p>EDIT: To clarify, I see this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
      &lt;string-array name="certs"&gt;
         &lt;item&gt;MIIEqDCCA5CgAwIBAgIJA071MA0GCSqGSIb3DQEBBAUAMIGUMQsww...&lt;/item&gt;
      &lt;/string-array&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>But do not see any information on where <code>MIIEqDCCA5CgAwIBAgIJA071MA0GCSqGSIb3DQEBBAUAMIGUMQsww...</code> is retrieved, especially with regards to EmojiCompat.</p>
