What have customers told us about “Synchronized

Profile”

People have multiple devices and want to transition between devices.

Implementing a user profile that syncs across devices, OS, apps is hard.

Work Offline

Data always stored in local SQLite DB first.

Works seamlessly when intermittent or no

connectivity

k/v data

(38)

Amazon Cognito Sync

Offline: The client SDK manages a local SQLite data store to allow the app to work even when connectivity is not available.

Fast: The methods to read and write data only interact with the local SQLite database.

Intelligent Sync: The sync method compares the local version of the data to the cloud sync store, pushes up deltas and pulls down new changes.

Flexible Conflict resolution: The sync method first reads the changes then writes its local changes to the cloud sync store By default Cognito assumes that the

last write wins. Developers can override and

implement their own conflict resolution programmatically

(39)

Integrating Cognito Sync functionality is dead simple

Initialize the CredentialsProvider and CognitoClient

Call synchronize on the dataset

Create or open Dataset and Add Key Values

provider = new CognitoCredentialsProvider(context, AWS_ACCOUNT_ID, COGNITO_POOL_ID, COGNTIO_ROLE_UNAUTH, COGNITO_ROLE_AUTH);

cognito = new DefaultCognitoSyncClient(context, COGNITO_POOL_ID, provider);

(40)

Integrating Cognito Sync functionality is dead simple

Initialize the AWSCognitoSyncClient

Call synchronize on the dataset

Create or open Dataset and Add Key Values

DataSet *dataset = [syncClient openOrCreateDataSet:@"myDataSet"]; NSString *value = [dataset readStringForKey:@"myKey"];

[dataset putString:@"my value" forKey:@"myKey"];

AWSCognitoSyncClient *syncClient = [[AWSCognitoSyncClient alloc] initWithConfiguration: configuration];

[dataset synchronize];

What Customers Told Us About “Mobile Analytics”

Developers deeply value user analytics and consider it an integral part

of their app development process. They want to monitor their most

Getting Started with Mobile Analytics in 3 steps

the AWS Management Console

AWS Management console within minutes

Key Business Metrics

2. Daily Active Users

3. New Users,

4. Daily Sessions,

5. Sticky Factor,

6. 1-Day Retention,

7. Avg. Revenue per DAU,

8. Daily Paying Users,

(48)

Track Retention

User retention is a key

indicator to judge the

outcome of a marketing

campaign, new feature

introduction, UX changes,

app updates, etc.

Mobile Analytics provide four

charts to track daily or

(49)

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

(50)

Integrating Mobile Analytics is super simple

Initialize the AmazonMobileAnalyticsClient. That’s it! Get Session

Activity in the AWS Management Console.

For Custom Events activity reports, add events.

Add OnResume() and OnPause()

analytics = new AmazonMobileAnalytics(provider, context, "SnakeGameAWS”);

EventClient eventClient = analytics.getEventClient();

MobileAnalyticsEvent visitEvent = eventClient.createEvent("speedSet"); eventClient.recordEvent(visitEvent);

(51)

Integrating Mobile Analytics is super simple

Initialize the AmazonMobileAnalytics object. That’s it! Get Session

Activity in the AWS Management Console.

Submit the event. If we don't call submitEvents, events

will automatically be submitted at periodic intervals.

Create add Custom Events

[eventClient submitEvents];

id<AWSMobileAnalyticsEventClient> eventClient = analytics.eventClient; id<AWSMobileAnalyticsEvent> level1Event = [eventClient

createEventWithEventType:@"level1Complete"];

AWSMobileAnalytics* analytics = [AWSMobileAnalytics

defaultAWSMobileAnalyticsWithIdentifier:@"someuniqueid"];

Amazon S3 Connector: Transfer Manager

S3 Connector

• Multipart upload/download media

to/from S3 (photos, videos, audio)

• No backend required

• Automatic retries

• Pause, resume, cancel functions

// Creating the transfer manager

self.transferManager = [S3TransferManager new];

self.transferManager.s3 = s3client;

// Upload image

[self.transferManager uploadFile:fileName bucket:bucketName key:objectName];

// Download image

[self.transferManager downloadFile:fileName bucket:bucketName key:objectName];

// Pause, Resume, Cancel

[self.transferManager pauseAllTransfers];

[self.transferManager resumeAllTransfers];

[self.transferManager cancelAllTransfers];

Each platform works differently, and push gets even more

complex as you scale to support millions of devices.
