public static class NotificationCompat.MessagingStyle
extends NotificationCompat.Style


Helper class for generating large-format notifications that include multiple back-and-forth messages of varying types between any number of people.
In order to get a backwards compatible behavior, the app needs to use the v7 version of the notification builder together with this style, otherwise the user will see the normal notification view.
Use setConversationTitle(CharSequence) to set a conversation title for group chats with more than two people. This could be the user-created name of the group or, if it doesn't have a specific name, a list of the participants in the conversation. Do not set a conversation title for one-on-one chats, since platforms use the existence of this field as a hint that the conversation is a group.
This class is a "rebuilder": It attaches to a Builder object and modifies its behavior, like so:

 Notification notification = new Notification.Builder()
     .setContentTitle("2 new messages with " + sender.toString())
     .setStyle(new Notification.MessagingStyle(resources.getString(R.string.reply_name))
         .addMessage(messages[0].getText(), messages[0].getTime(), messages[0].getSender())
         .addMessage(messages[1].getText(), messages[1].getTime(), messages[1].getSender()))
