- ADEP (Adobe Data Enterprise Platform) allows building data-intensive native mobile apps that connect to backend services using similar APIs across platforms like iOS, Android, HTML5. - The APIs are designed to be simple and consistent while respecting platform differences. Remote procedure calls and messaging features are supported across clients. - Code samples demonstrate creating channels, remote objects, producers and consumers to call services and receive real-time messages on different platforms in a similar way.

Hand in your surveys to the room monitors One survey per session will be selected as a winner of an Adobe Press e-book or Video Introduction to Adobe Edge Web Design with Muse (code name) from Adobe Android App Development and Design: Learn by Video Winners will be notified via e-mail at the end of each day Turn in your surveys for a chance to WIN!

3. Assumptions You are an enterprise Flash and/or Java developer You used (or at least heard about) Data Services (or at least BlazeDS) before You are interested in building data-intensive native mobile applications talking to some backend. 3

4. Demos 4

5. Key takeaways from the demo All client applications are native. All clients are talking to the same server. 5

6. Technology Overview — Data Services - Before 6 AIR Flex

7. Technology Overview — Data Services - Now 7 Objective-C Android HTML5/JS Flex/AIR Java

8. Motivation and Goal Client choice should not dictate server choice. Make sure Data Services benefits are realized in multiple types of clients natively: Efficient data transfer Real-time connectivity Rich and easy-to-use APIs 8

11. API Philosophy Keep APIs as simple as possible. Keep APIs as similar as possible across platforms but respect platform differences where it makes sense. Some differences In ActionScript, subclasses of Channel handle encoding, HTTP modes, SSL. In new clients, a single Channel handles these via properties and automatically. In ActionScript, remoting and messaging are event driven. In Java/Android client, remoting is a synchronous call whereas messaging is still event driven. In ActionScript, remoting can make calls to non-existent methods on the client to invoke remote methods on the server. In new clients, “invoke” method is called with the remote method name. 11

12. Code Samples – Creating Channel // ActionScript varchannel:Channel= new AMFChannel(channelId, channelUrl); // Java/Android Channel channel = new Channel(channelId, channelUrl, httpMode, encoding, sslContext); // HTML5/JavaScript varchannel = new flex.client.channels.Channel(channelId, channelUrl, httpMode); // Objective-C DSChannel*channel = [[DSChannelalloc] initWithId:channelIdurl:channelUrlhttpMode:httpMode]; 12

13. Code Samples – Creating ChannelSet // ActionScript varchannelSet:ChannelSet= new ChannelSet(); channelSet.addChannel(channel); // Java/Android ChannelSetchannelSet = new ChannelSet(channels); // HTML5/JavaScript varchannelset = new flex.client.channels.ChannelSet(channels); // Objective-C DSChannelSet *channelSet = [DSChannelSetchannelSetWithChannels:[NSArrayarrayWithObjects:channels]]; 13

14. Code Samples – Creating RemoteObject // ActionScript varremoteObject = new RemoteObject(); remoteObject.destination= destinationId; // Java/Android RemoteObjectremoteObject= new RemoteObject(destinationId); // HTML5/JavaScript varremoteObject = new flex.client.rpc.remoting.RemoteObject(destinationId); // Objective-C DSRemoteObject *remoteObject = [[[DSRemoteObjectalloc] initWithDestinationId:destinationId]; 14

15. Code Samples – Invoking RemoteObject // ActionScript remoteObject.echo(“Hello World!”); // Java/Android Object result = remoteObject.invoke(“echo”, “Hello World!”); // HTML5/JavaScript remoteObject.invoke(“echo”, “Hello World!”); // Objective-C [remoteObject invoke:@”echo” args:[NSArrayarrayWithObject:@”Hello World!”] delegate:self selector:@selector(invocationResultHandler:)]; 15

16. Code Samples – Creating Producer // ActionScript varproducer:Producer = new Producer(); producer.destination = destinationId; // Java/Android Producer producer = new Producer(destinationId); // HTML5/JavaScript var producer = new flex.client.messaging.Producer(destiantionId); // Objective-C DSProducer *producer = [[DSProduceralloc] initWithDestinationId:destinationId]; 16

17. Code Samples – Sending Message // ActionScript varmessage:AsyncMessage = new AsyncMessage(); message.body = “Hello World!”; producer.send(message); // Java/Android AsyncMessage message = new AsyncMessage(); message.setBody(“Hello World!”); producer.send(message); 17

18. Code Samples – Creating Consumer & Subscribing // ActionScript varconsumer:Consumer = new Consumer(); consumer.destination = destinationId; consumer.subscribe(); // Java/Android Consumer consumer = new Consumer(destinationId); consumer.subscribe(); // HTML5/JavaScript var consumer = new flex.client.messaging.Consumer(destinationId); consumer.subscribe(); // Objective-C DSConsumer *consumer = [[DSConsumeralloc] initWithDestinationId:destinationId]; [consumer subscribe]; 18

19. Code Samples – Adding Event Listeners // ActionScript consumer.addEventListener(MessageEvent.MESSAGE, messageHandler); consumer.addEventListener(MessageFaultEvent.FAULT, faultHandler); // HTML5/JavaScript consumer.addEventListener(flex.client.messaging.events.MessageEvent.MESSAGE, messageHandler); consumer.addEventListener(flex.client.messaging.events.MessageFaultEvent.FAULT, faultHandler); 19

20. Code Samples – Receiving Message // ActionScript private function messageHandler(messageEvent:MessageEvent):void { // Consumer received message: messageEvent.message.body; } // HTML5/JavaScript function messageHandler(messageEvent) { // Consumer received message: messageEvent.getMessage().getBody(); } 20
