// Creating the transfer manager

AmazonS3 s3 = new AmazonS3Client(credentialsProvider);

s3.setRegion(Region.getRegion(Regions.MY_BUCKET_REGION));

TransferUtility transferUtility = new TransferUtility(s3, APPLICATION_CONTEXT);

// Upload file

TransferObserver observer = transferUtility.upload( MY_BUCKET, OBJECT_KEY,

MY_FILE);

// Download file

TransferObserver observer = transferUtility.download( MY_BUCKET, OBJECT_KEY,

MY_FILE);

// Pause, Resume, Cancel

transferUtility.pause(idOfTransferToBePaused);

transferUtility.resume(idOfTransferToBeResumed);

transferUtility.cancel(idToBeCancelled);



// Creating the transfer manager

AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager];

// Download file

AWSS3TransferManagerDownloadRequest *downloadRequest = [AWSS3TransferManagerDownloadRequest

new];

downloadRequest.bucket = @"myBucket";

downloadRequest.key = @"myImage.jpg";

downloadRequest.downloadingFileURL = downloadingFileURL;

// Upload File

AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new];

// Pause and Resume File Download

[downloadRequest pause]; [transferManager download:downloadRequest];



Analyze User Behavior: Amazon Mobile Analytics


Amazon Mobile Analytics

Scalable and Generous Free Tier

Focus on metrics that matter. Usage reports available within 60 minutes of

receiving data from an app

Fast

Scale to billions of events per day from

millions of users.

Own Your Data

“Easily collect, visualize and understand your app usage data at scale”

Data collected are not shared, aggregated, or

reused


Getting Started with Mobile Analytics in 3 steps

Sign up for AWS Account and create or use existing Cognito ID in the AWS Management Console

View engagement and session activity reports in the AWS Management console within minutes

Download and integrate the Mobile SDK with one line of code (Android/FireOS, iOS)


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


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

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

Track Custom Events


Integrating Mobile Analytics is simple

Initialize the MobileAnalyticsManager. That’s it!

For Custom Events activity reports, add events.

Add OnResume() and OnPause()

private static MobileAnalyticsManager analytics;analytics = MobileAnalyticsManager.getOrCreateInstance (this.getApplicationContext(), "appId", "identityPoolId”);

EventClient eventClient = analytics.getEventClient();MobileAnalyticsEvent levelCompleteEvent=eventClient.createEvent("LevelComplete");eventClient.recordEvent(levelCompleteEvent);

analytics.getSessionClient().resumeSession();analytics.getSessionClient().pauseSession();analytics.getEventClient().submitEvents();


Integrating Mobile Analytics is simple

Initialize the AWSMobileAnalytics object. That’s it!

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> levelEvent = [eventClient createEventWithEventType:@"LevelComplete"];

AWSMobileAnalytics *analytics = [AWSMobileAnalytics mobileAnalyticsForAppId:@"yourAppId" identityPoolId: @"cognitoId"];

Bob 750

Amazon DynamoDB Connector: Object Mapper

Simplifies access to Amazon DynamoDB in your app

Map client-side classes to Amazon DynamoDB tables

Removes the need to transform objects into tables and vice versa


Amazon DynamoDB: Example@DynamoDBTable(tableName = ”Highscores")

public static class HighScore{

private int id, highScore;

private String name;

@DynamoDBHashKey(attributeName = "id")

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

@DynamoDBAttribute(attributeName=”name")

public String getName() {

return name;

}……

id name highscore

17 Joe 25

23 Anna 67

32 Bob 55

Table: Highscores


Amazon DynamoDB: Example// Build a highscore object

HighScore highScore = new HighScore();

highScore.setId(17);

highScore.setName(”Joe");

highScore.setHighScore(25);

// Save book object to dynmaoDB

mapper.save(highScore);

// Update item and save object again

highScore.setHighScore(118);

mapper.save(highScore);

// Load another book

HighScore anotherHighScore = mapper.load(HighScore.class,23);


Some Best Practices for Backend Services

S3: • How you name your S3 Objects is very Important.• Randomize the prefix of your object keys to ensure better distribution on

S3’s partitions.• You don’t have to worry about the bucket name itself.• If your app is GET heavy on S3 Objects, consider using CloudFront

DynamoDB:• Keep item size small• Store metadata in Amazon DynamoDB and large blobs in Amazon S3 • Avoid hot keys and hot partitions• Use conditional/OCC updates

• Set up Cognito Identity Pool– Create Grumpy Flappy Identity Pool– Retrieve Identity Pool ID

• Set up Mobile Analytics App– Add Grumpy Flappy App– Retrieve App ID


Grumpy Flappy Demo

Amazon Cognito: Unity3D Code


Adding DynamoDB

• Create DynamoDB Table– Using DynamoDB Console– Using code with createTable method– Using Visual Studio with AWS Toolkit for Visual Studio:

http://aws.amazon.com/net/ – Example:

• Table Name: GrumpyScoreTable • Primary Key Type: Hash• Hash Attribute Name: PlayerID, • Hash Type: Number

• Create DynamoDB ClientAmazonDynamoDBClient client = new AmazonDynamoDBClient(RegionEndpoint.USEast1)

http://aws.amazon.com/net/



Using DynamoDB• Add a High Score Record

– Create High Score Object[DynamoDBTable("GrumpyScoreTable")]class FlappyScoreData{ [DynamoDBHashKey] // hash key public int PlayerID { get; set; } [DynamoDBProperty] public int LastScore { get; set; } [DynamoDBProperty]

public int HighScore {get; set; }}

– Save High Score Record to DynamoDB_context.SaveAsync<HighScore>(myScore, (AmazonDynamoResult<VoidResponse> result) =>

{ if (result.Exception != null) { this.displayMessage += "Save failed ; “ +result.Exception.Message; }


Adding Simple Storage Service (S3)

• Create S3 Bucket (set permissions)– Using S3 Console– Using code with PutBucket and PutBucketRequest– Using Visual Studio with AWS Toolkit for Visual Studio:

http://aws.amazon.com/net/ – Example:

• Bucket Name: grumpyflappy_bucket

• Create an S3 Transfer ManagerAmazonS3Client S3Client =

new AmazonS3Client (credentials ,RegionEndpoint.USEast1);



Using Simple Storage Service (S3)• Download an Object

– Get Badge Picture (bragging rights)var request = new GetObjectRequest (){ BucketName = bucketName, Key = downloadKey,};S3Client.GetObjectAsync (request, GetObjectCallback,null);

• Upload an ObjectStream stream = null;stream = new FileStream(uploadSrcFilePath, FileMode.Open, FileAccess.Read, FileShare.Read);var postRequest = new PostObjectRequest{ Key = uploadKey, Bucket = bucketName, InputStream = stream };S3Client.PostObjectAsync (postRequest, PostObjectCallback,null);
