1 2Android MessagingService Sample 3=================================== 4 5This sample shows a simple service that sends notifications using 6NotificationCompat. In addition to sending a notification, it also extends 7the notification with a CarExtender to make it compatible with Android Auto. 8Each unread conversation from a user is sent as a distinct notification. 9 10Introduction 11------------ 12 13#### Checklist while building a messaging app that supports Android Auto: 141. Ensure that Message notifications are extended using 15NotificationCompat.Builder.extend(new CarExtender()...) 162. Declare a meta-data tag to your AndroidManifest.xml to specify that your app 17is automotive enabled. 18 19example: AndroidManifest.xml 20 21``` 22 <meta-data android:name="com.google.android.gms.car.application" 23 android:resource="@xml/automotive_app_desc"/> 24``` 25 26Include the following to indicate that the application wants to show notifications on 27the Android Auto overview screen. 28 29example: res/xml/automotive\_app\_desc.xml 30``` 31 <automotiveApp> 32 <uses name="notification"/> 33 </automotiveApp> 34``` 35 36#### Flow 37MessagingFragment is shown to the user. Depending on the button clicked, the MessagingService is 38sent a message. MessagingService in turn creates notifications which can be viewed either on the 39device or in the messaging-simulator. 40 41When a message is read, the associated PendingIntent is triggered and MessageReadReceiver is called 42with the appropriate conversationId. Similarly, when a reply is received, the MessageReplyReceiver 43is called with the appropriate conversationId. MessageLogger logs each event and shows them in a 44TextView in MessagingFragment for correlation. 45 46Pre-requisites 47-------------- 48 49- Android SDK v23 50- Android Build Tools v23.0.0 51- Android Support Repository 52 53Screenshots 54------------- 55 56<img src="screenshots/1-main.png" height="400" alt="Screenshot"/> <img src="screenshots/2-onemessage.png" height="400" alt="Screenshot"/> <img src="screenshots/3-threemessages.png" height="400" alt="Screenshot"/> 57 58Getting Started 59--------------- 60 61This sample uses the Gradle build system.
