Learn about AWS services specifically designed to help mobile app developers with identity management & sync (Amazon Cognito), analytics (Amazon Mobile Analytics), and push notifications (Amazon SNS Mobile Push). We will also explain how you can easily include these services in your apps using the AWS Mobile SDK. View a recording of this presentation as a webinar on YouTube here: http://youtu.be/5w8ntFp4_kc

21. Integrating Cognito Sync functionality
Initialize the CredentialsProvider and CognitoClient
Call synchronize on the dataset
Create or open Dataset and Add Key Values
provider = new CognitoCachingCredentialsProvider (context, AWS_ACCOUNT_ID,
COGNITO_POOL_ID, COGNITO_ROLE_UNAUTH, COGNITO_ROLE_AUTH, Regions.US_EAST_1);
cognito = new CognitoSyncManager (context, Regions.US_EAST_1, provider);
dataset.synchronize(new SyncCallback(){..});
cognito.openOrCreateDataset(datasetName);
dataset.put(key, value);

AWS Lambda
Auto Scaling
(Never under or over provision)
Starting with JavaScript but later
any language, Create threads
and processes, run batch scripts
or other executables
Zero administration Bring your own code
Run stateless functions in the cloud and scale without any servers to manage
Focus on business logic,
not infrastructure. Upload
your code; AWS Lambda
handles everything else
Lambda scales the
infrastructure as needed
to match the event rate
and pay as you go

24. How can you AWS Lambda to work?

27. Adding a Lambda Backend to your App
Initialize the LambdaFactory and define the Interface for the functions
Call localFunction object to execute Lambda Function
Create/Upload the Lambda Function to the AWS Management Console
lambda = new LambdaInvokerFactory(context, Regions.US_WEST_2, provider);
//interface
@LambdaFunction(functionName="cloudFunction”)
String localFunction(String nameInfo);
lambda.localFunction(“Hello From “); // this will output “Hello From Lambda”
exports.handler = function(event, context) {
context.done(null, event + 'Lambda'); // SUCCESS with message
};

28. ANALYZING USER BEHAVIOR

29. 1 2 3
Amazon Mobile Analytics
Scalable and Generous Free Tier
Data collected are not shared,
aggregated, or reused
Fast Own your data
Simply and cost effectively collect and analyze your application usage data
Focus on metrics that matter.
Usage reports available
within 60 minutes of
receiving data from an app
Scale to billions of
events per day from
millions of users

31. Key Business Metrics
(with one line of code)
1. Monthly Active Users (MAU)
2. Daily Active Users (DAU)
3. New Users,
4. Daily Sessions,
5. Sticky Factor,
6. 1-Day Retention,
7. Avg. Revenue per DAU,
8. Daily Paying Users,
9. Avg. Paying DAU

32. Track Custom Events
Get behavioral insights into app specific actions
that your users take
Reports provide a view of how often custom
events occur. You can add further context with
Attributes and Metrics, to each custom event
Examples
Track the number of
Likes/Shares, per
article, in a news app
Understand player
abort rates per level,
in a game
Number of songs
played, per user
session, in a music app
In-app item popularity
in a shopping app

33. Integrating Mobile Analytics
Initialize the MobileAnalyticsManager to get session activity in the AWS console
For Custom Events activity reports, add events
Add OnResume() and OnPause()
private static MobileAnalyticsManager analytics;
analytics = MobileAnalyticsManager.getOrCreateInstance(
this.getApplicationContext(),"yourCompany.yourAppId",
Regions.YOUR_REGION, config, cognitoProvider );
EventClient eventClient = analytics.getEventClient();
MobileAnalyticsEvent visitEvent = eventClient.createEvent("speedSet");
eventClient.recordEvent(visitEvent);
analytics.getSessionClient().resumeSession();
analytics.getSessionClient().pauseSession();
Analytics.getEventClient().submitEvents();

Multipart upload media (photos, videos, audio)
Fault tolerant download (e.g. assets)
No backend required
Automatic retries
Pause, resume, cancel functions
Optimized for native OS

41. Amazon S3 Connector: Transfer Manager
Creating the transfer manager
Pause & resume transfers
Upload & download image
TransferManager transferManager = new TransferManager(credentialProvider);
try {
PersistableDownload persistableDownload = download.pause();
//do something if we didn’t abort
} catch(PauseException e) {
//do something if we aborted
}
download = transferManager.resumeDownload(persistableDownload);
Upload upload = transferManager.upload(BUCKET_NAME, fileName, file);
Download download = transferManager.download(BUCKET_NAME, mKey, file);
