<h3 id="#concepts">Concepts and Objects</h3>
<p>Before you start designing your app, it's helpful to understand how Auto
handles messaging.</p>
<p>Each individual chunk of communication is a <em>message</em>. A message is a
short length of text, suitable for the Auto device to read aloud. In a chat app,
this might be a single message from one person to another: <code>"Fitzy -- Jane
can't come to the ball, her youngest has the croup. :-( --Liz"</code> In a
sports app, a message might be a single bit of news about a game: <code>"Granger
scores for Harpies at 7 minutes in."</code></p>
<p>A <em>conversation</em> is a group of messages that are all grouped together
in some way. Auto uses the conversation information to group the messages
together when presenting them to the user. In a chat app, a conversation might
be all the messages between the user and another person (for example, all
the messages back and forth between Darcy and Elizabeth). In a sports app, a
conversation might be all the messages about a particular game. Every message
belongs to a conversation, even if it's the only message in that conversation.
Each conversation has a <em>conversation name</em>.
The conversation name is used by Android Auto to
present the messages; it's up to your app to choose an appropriate conversation
name. In a chat app, the conversation name is usually the person your user is
talking to.
In a sports app, this might be the name of the teams playing in the game.</p>
<p>The v4 support library defines an {@link
android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation
UnreadConversation} object. This object holds all messages in a conversation
which have not yet been heard by the user. To give those messages to the user,
you attach that {@link
android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation
UnreadConversation} to a notification. However, you do not attach messages to
the {@link
android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation
UnreadConversation} directly. Instead, you must first set up an {@link
android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation.Builder
UnreadConversation.Builder} object for the conversation. The messages are added to the builder,
then when you are ready to send the messages, you use the builder to create the
actual {@link
android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation
UnreadConversation} and attach the {@link
android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation
UnreadConversation} to the notification.</p>
<p class="note"><strong>Note:</strong> When Auto presents messages to the
user, it uses the notification <em>tag</em> and <em>ID</em> to determine which conversation the
messages belong to. It is important to use the same tag and ID for all messages in
a conversation, and to not use that tag for other conversations.</p>
<h3 id="#workflow">Workflow</h3>
<p>This section describes how the mobile device interacts with Auto to present
messages to the user.</p>
<ol>
<li>The app receives a message that it wants to pass on to the user. It attaches
the message to an {@link
android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation
UnreadConversation} object and attaches it to a notification. That notification
is associated with a {@link
android.support.v4.app.NotificationCompat.CarExtender CarExtender} object, which
indicates that the notification can be handled by Android Auto.</li>
<li>The app posts the notification. The Android notification framework passes the
message to Auto. Auto uses the notification tag and ID to determine which conversation
the message belongs to, and presents the message to the user in an appropriate
way.</li>
<li>When the user listens to the message, Auto triggers the app's message heard
pending intent. The app should discard the {@link
android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation
UnreadConversation} object and its builder at this time, since the messages
contained in those objects have been heard by the user.</li>
<li>If the user sends a reply, Auto triggers the app's "message reply" intent and
attaches a transcript of the user's response. The app can take appropriate
action, based on the app's logic. For example, a chat app might interpret the
reply as a message to go to the other conversation participants, while a sports
app might try to interpret the "reply" as a request for other information
("What's the score in the Sharks game?").</li>

Messaging notifications for Auto organize messages into conversations using the {@link
android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation} class,
that represents an unread or new
portion of a conversation from a particular sender. It contains a list of messages from the
sender.
</p>
<p>
Use the {@link android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation.Builder} class to create an unread conversation object,
as shown in the following example code:
</p>
<pre>
// Build a RemoteInput for receiving voice input in a Car Notification
RemoteInput remoteInput = new RemoteInput.Builder(EXTRA_VOICE_REPLY)
.setLabel(getApplicationContext().getString(R.string.notification_reply))
.build();
// Create an unread conversation object to organize a group of messages
// from a particular sender.
UnreadConversation.Builder unreadConvBuilder =
new UnreadConversation.Builder(participantName)
.setReadPendingIntent(msgHeardPendingIntent)
.setReplyAction(replyPendingIntent, remoteInput);
</pre>
<p>
This conversation object includes a {@link android.app.PendingIntent}, which allows the Auto
device to signal your app that the conversation has been read by the Auto user. The construction
of this intent is discussed in the <a href="#conversation-intents">Creating conversation read and
reply intents</a> section.
</p>
<p>
If your app supports replying to a conversation, you must call the {@link android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation.Builder#setReplyAction setReplyAction()}
method and provide a pending intent to pass that user action back to your app. The
{@link android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation}
object you create must also include a {@link
android.support.v4.app.RemoteInput} object. When the Auto user
receiving this conversation speaks a reply, the remote input objects lets your app get a text
version of the voice reply.
</p>
<h4 id="conversation-messages">Associate messages with conversations</h4>
<p>
Messages provided for Auto must be associated with a conversation using the
{@link android.support.v4.app.NotificationCompat.CarExtender.UnreadConversation}
class. The following code example shows how
to associate individual messages with a conversation object.
</p>
<pre>
// Note: Add messages from oldest to newest to the UnreadConversation.Builder
for (Iterator&lt;String&gt; messages = conversation.getMessages().iterator();
messages.hasNext(); ) {
String message = messages.next();
unreadConvBuilder.addMessage(message);
}
</pre>
<p>
When a new message arrives in a particular conversation, your app should check if there is
already a conversation object for that particular conversation. If there is, associate the new
message with the existing conversation instead of building a new one.
