+Android Auto Messaging API Sample
+=================================
+
+MessagingService.java shows a simple service that sends notifications using NotificationCompat.
+In addition to sending a notification, it also extends the notification with a CarExtender.
+Each unread conversation from a user is sent as a distinct notification.
+
+CheckList while building a messaging app that supports Android Auto:
+-------------------------------------------------------------------
+1. Add or import the android-auto-sdk.jar into your app.
+2. Ensure that Message notifications are extended using
+NotificationCompat.Builder.extend(new CarExtender()...)
+3. Add meta-data to your AndroidManifest.xml to specify that your app
+is automotive enabled.
+
+       <meta-data android:name="com.google.android.gms.car.application"
+                   android:resource="@xml/automotive_app_desc"/>
+
+and include the following to indicate that the application wants to show notifications on
+the overview screen.
+res/xml/automotive_app_desc.xml
+
+<automotiveApp>
+    <uses name="notification"/>
+</automotiveApp>
+
+Flow
+-----
+MessagingFragment is shown to the user. Depending on the button clicked, the MessagingService is
+sent a message. MessagingService inturn creates notifications which can be viewed either on the
+emulator or in a car.
+When a message is read, the associated PendingIntent is called and MessageReadReceiver is called
+with the appropriate conversationId. Similarly, when a reply is received, the MessageReplyReceiver
+is called with the appropriate conversationId. MessageLogger logs each event and shows them in a
+TextView in MessagingFragment for correlation.
+
+Known Issues:
+-------------
+- Emulator: Reply always sends text "This is a reply". No voice input in emulator.
