1 2 Android MessagingService Sample 3 =================================== 4 5 This sample shows a simple service that sends notifications using 6 NotificationCompat. In addition to sending a notification, it also extends 7 the notification with a CarExtender to make it compatible with Android Auto. 8 Each unread conversation from a user is sent as a distinct notification. 9 10 Introduction 11 ------------ 12 13 #### Checklist while building a messaging app that supports Android Auto: 14 1. Ensure that Message notifications are extended using 15 NotificationCompat.Builder.extend(new CarExtender()...) 16 2. Declare a meta-data tag to your AndroidManifest.xml to specify that your app 17 is automotive enabled. 18 19 example: AndroidManifest.xml 20 21 ``` 22 <meta-data android:name="com.google.android.gms.car.application" 23 android:resource="@xml/automotive_app_desc"/> 24 ``` 25 26 Include the following to indicate that the application wants to show notifications on 27 the Android Auto overview screen. 28 29 example: res/xml/automotive\_app\_desc.xml 30 ``` 31 <automotiveApp> 32 <uses name="notification"/> 33 </automotiveApp> 34 ``` 35 36 #### Flow 37 MessagingFragment is shown to the user. Depending on the button clicked, the MessagingService is 38 sent a message. MessagingService in turn creates notifications which can be viewed either on the 39 device or in the messaging-simulator. 40 41 When a message is read, the associated PendingIntent is triggered and MessageReadReceiver is called 42 with the appropriate conversationId. Similarly, when a reply is received, the MessageReplyReceiver 43 is called with the appropriate conversationId. MessageLogger logs each event and shows them in a 44 TextView in MessagingFragment for correlation. 45 46 Pre-requisites 47 -------------- 48 49 - Android SDK v23 50 - Android Build Tools v23.0.0 51 - Android Support Repository 52 53 Screenshots 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 58 Getting Started 59 --------------- 60 61 This sample uses the Gradle build system.
