This sample shows a simple service that sends notifications using NotificationCompat. In addition to sending a notification, it also extends the notification with a CarExtender to make it compatible with Android Auto. Each unread conversation from a user is sent as a distinct notification.
- Ensure that Message notifications are extended using NotificationCompat.Builder.extend(new CarExtender()...)
- Declare a meta-data tag to your AndroidManifest.xml to specify that your app is automotive enabled.
example: AndroidManifest.xml
<meta-data android:name="com.google.android.gms.car.application"
android:resource="@xml/automotive_app_desc"/>
Include the following to indicate that the application wants to show notifications on the Android Auto overview screen.
example: res/xml/automotive_app_desc.xml
<automotiveApp>
<uses name="notification"/>
</automotiveApp>
MessagingFragment is shown to the user. Depending on the button clicked, the MessagingService is sent a message. MessagingService in turn creates notifications which can be viewed either on the device or in the messaging-simulator.
When a message is read, the associated PendingIntent is triggered 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.
