Deep-Dive: Building Native iOS and Android Application with the AWS Mobile SDK
- 1. © 2016, Amazon Web Services, Inc. or its Affiliates. All rights reserved. John Burry, Sr Mgr AWS Solutions Architecture October 25, 2016 Deep-Dive: Building Native iOS and Android Application with the AWS Mobile SDK
- 3. Fully Integrated AWS Mobile SDK • Cross-Service authentication mechanism • Handle intermittent network connections • Android, iOS, Fire OS, Unity, JavaScript • Reduced memory footprint, battery impact, etc.
- 4. Native Android 1. Import JARs 2. Gradle 3. Maven iOS 1. Import .framework files 2. Cocoapods 1. sudo gem cocoapods 2. 3. pod install 4. *.xcworkspace not *xcodeproj
- 5. Mobile SDK Cognito • Unique Identity • Scoped, temp credentials • Cross Device Sync S3 • Partitioning & Parallel transmission • Retransmits, handles intermittent networks DDB • ORM interface • Conditional/Batch writes • “low-level client” API Gateway & Lambda Mobile Analytics • Standard events • Custom events • Persist and batch send Kinesis • Store and serialize • Streams or Firehose • Send Payloads in batch • Records sent if devices go offline Can just use REST • SDKs on GitHub Swift • Compatible - Use in your project!
- 6. “AWS has what I need, but…I am new here” 1. Which services should I use? 2. How do I connect them? Identity Provider SDKs + <Example> Login screen & integration code + SDK
- 7. Mobile Hub as a Starting Point • Generates Working Code to Explore • Introduction to AWS SDK features and functions • iOS and Android interaction with AWS Services
- 8. AWS Mobile Hub (beta) 1. Single integrated console 2. Pre-built features 3. Auto-provisioned services 4. Auto-generated app Result: Build Apps on AWS in Minutes
- 10. + Feature Server-side validation/persistence AWS Service Code generation Testing Authentication Survey files (json) State and sync between devices Analytics Device Farm Cognito Datastore Mobile Analytics 100% Serverless Recap: Mobile Hub Sample Architecture Lambda + DynamoDB Mobile Hub Cognito (Facebook) S3 1. 2. 3. 4. 5. 6. 7.
- 11. Gather: Mobile Analytics SDK (Android, iOS, JavaScript, Unity, Xamarin) REST API Amazon MobileAnalytics Daily/Monthly Active Users Sessions Sticky Factor In-app Revenue Lifetime Value (LTV) Retention …. and more (Pre-defined metrics with a few lines of code) Amazon S3 Amazon Redshift Amazon DynamoDB Amazon EMR Amazon Machine Learning Amazon API Gateway Amazon Elasticsearch Service Amazon RDS
- 12. Assume a Role with Cognito Create an instance of your Mobile Analytics Application Create->Record->Submit Events Submitting Events: Android Example
- 13. API Gateway API Gateway AWS Lambda Any other publicly accessible endpoint Amazon EC2 API Gateway Generated SDK - Signed Requests Cognito: User Pools + Identity
- 14. API Gateway generated SDK
- 15. Provider (APNS, GCM, MPNS,…) Token Request Amazon SNS SNS Platform Application “Token” Platform Endpoint - Upload Certificates, API Keys, etc. Upload Token - AKA “Create Platform Endpoint” - Client code in App Delegate, etc. Lifecycle of Push Notifications
- 16. Fine-grained control Send to Mobile Analytics Sync Datasets across devices Add Token to SNS Add email/phone to SNS
- 17. Provider (APNS, GCM, MPNS,…) Amazon SNS Platform Application “Token” Platform Endpoint Upload Token - AKA “Create Platform Endpoint” Add Email to Topic Add Phone to Topic Alternative Options Amazon API Gateway Amazon Cognito User Pool AWS Lambda Topic Workflow Triggers /myapi/register Custom Authorizers
- 18. Cognito Datasets
- 19. Cognito Dataset Push Sync - Dataset changes pushed to devices via SNS Events - Execute Lambda functions when Datasets sync Streams - Dataset changes sent to Kinesis
- 20. DynamoDB Access via Cognito assigned Role Databases Relational Create interfaces - REST/GraphQL/JSON-API - API Gateway, ELB/ALB - Common: ASG behind ELB using RDS Multi-AZ - Platform HTTP calls - iOS: NSURLConnection, NSURLSession, etc. - Android: HttpClient(), HttpGet(),etc.
- 21. Hybrid Apps
- 22. Cordova Formerly known as Phonegap Create Mobile Apps with HTML, CSS, JavaScript Extended via plugins WebView intermediary for rendering/communicating with platform Ionic • UI Framework build on Cordova using Angular
- 23. Using AWS Services from Cordova 1. Download & include aws-sdk.min.js 2. Reference in Cordova’s index.html 3. Grant AWS endpoints access 4. Call AWS SDK functions from index.js • Start with Cognito in onDevice
- 25. Push Notifications and Cordova Yes you can initiate SNS-based Push to Cordova! ANDROID: $cordova plugin add phonegap-plugin-push –variable SENDER_ID="YOURID" iOS: $cordova plugin add phonegap-plugin-push
- 26. React Native AWS Published SDK available • AWSLABS https://github.com/awslabs/aws-sdk-react- native Can easily add in AWS Native SDKs
- 27. Customizing React Native with AWS SDKs 1. Import Native AWS SDK & Bridging Modules 2. Create Singleton
- 28. Customizing React Native with AWS SDKs 3. Initialize in JavaScript 3. Add/Invoke methods
- 29. Thank You!
Editor's Notes
- AWS Mobile SDKs: Libraries with high-level interfaces which are optimized for mobile networks and platforms to access AWS services. Cognito - Facilitates scoped, temp credentials for accessing AWS services securely and assigns unique identification to users or devices throughout the lifetime of an application. - Associate or join Public or Custom identity providers with Cognito assigned identification to control access to AWS resources - Synchronizes key/value datasets across devices based on triggers and persists data securely to local storage S3 - Breaks up files to transfer into multiple pieces for parallel transmission, retransmits and handles intermittent networks DDB - Provides an abstract ORM interface to DynamoDB items and attributes to easily read & write to a persistent NoSQL - Conditional writes & batch writes use a “low-level client” (direct message send/method call) Lambda - Invoke Lambda functions with a custom class method Mobile Analytics - Persist standard (user sessions, retention, etc.) and custom MA events locally and send in batch for efficient device usage Kinesis - Store and serialize data payloads for transmission to Kinesis Streams or Kinesis Firehose (separate classes) - PutRecord payloads are stored on disk to be sent in batch for more efficient network usage & battery life - Ensures records are sent if devices go offline through application lifecyle
- Note that the services on the left are a “Pull Model” “Push Model” also includes SNS
- Note how you can use the Mobile Analytics options to either send events over all networks or just WiFi
- Microservices and Serverless
- Note that messages to device and from AWS to provider requires authn/authz that’s why we need Certs, API keys, etc.
- #3 will also need to add amazonaws.com to config.xml in Cordova project
- YOURID is the Google Cloud Messaging Project ID Modify index.js with an event listener for the GCM registration ID or iOS device token
- Note we’re also using Push Notifications with React Native
