 Best Practices
 --------------
 
 ## Android notification channels
 
 ### Set default channel
 
 If incoming FCM messages do not specify an Android notification channel, you can indicate
 to FCM what channel should be used as the default by adding a metadata element to your
 application manifest. In the metadata element specify the ID of the channel that should
 be used by default by FCM.
 
  <meta-data
   android:name="com.google.firebase.messaging.default_notification_channel"
   android:value="default_channel_id"/>
 
 Note: You are still required to create a notification channel in code with an ID that
 matches the one defined in the manifest. See the Android [docs](https://goo.gl/x9fh5X) for more.
 
 ## Customize default notification
 
 ### Custom default icon
