1 2 Android MessagingService Sample 3 =================================== 4 5 This sample shows a simple service that sends notifications using 6 NotificationCompat. It also extends the notification with Remote 7 Input to allow Android N devices to reply via text directly from 8 the notification without having to open an App. The same Remote 9 Input object also allows Android Auto users to respond by voice 10 when the notification is presented there. 11 Note: Each unread conversation from a user is sent as a distinct 12 notification. 13 14 Introduction 15 ------------ 16 17 #### Checklist while building a messaging app that supports Android Auto: 18 1. Ensure that Message notifications are extended using 19 NotificationCompat.Builder.extend(new CarExtender()...) 20 2. Declare a meta-data tag to your AndroidManifest.xml to specify that your app 21 is automotive enabled. 22 23 example: AndroidManifest.xml 24 25 ``` 26 <meta-data android:name="com.google.android.gms.car.application" 27 android:resource="@xml/automotive_app_desc"/> 28 ``` 29 30 Include the following to indicate that the application wants to show notifications on 31 the Android Auto overview screen. 32 33 example: res/xml/automotive\_app\_desc.xml 34 ``` 35 <automotiveApp> 36 <uses name="notification"/> 37 </automotiveApp> 38 ``` 39 40 #### Flow 41 MessagingFragment is shown to the user. Depending on the button clicked, the MessagingService is 42 sent a message. MessagingService in turn creates notifications which can be viewed either on the 43 device or in the messaging-simulator. 44 45 When a message is read, the associated PendingIntent is triggered and MessageReadReceiver is called 46 with the appropriate conversationId. Similarly, when a reply is received, the MessageReplyReceiver 47 is called with the appropriate conversationId. MessageLogger logs each event and shows them in a 48 TextView in MessagingFragment for correlation. 49 50 Pre-requisites 51 -------------- 52 53 - Android SDK 24 54 - Android Build Tools v24.0.2 55 - Android Support Repository 56 57 Screenshots 58 ------------- 59 60 <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"/> 61 62 Getting Started 63 --------------- 64 65 This sample uses the Gradle build system.
