Mobile SDKs are a great way to make your service or API easily consumable by the large number of developers out there looking for state of the art tools to make their apps stand out in the competitive marketplaces, but building a stable, compatible and successful SDK is quite a challenge. In this talk we the technical and design challenges involved in developing an efficient mobile SDK that is highly compatible with its host mobile app, and the various considerations we took into account and the lessons we’ve learned while designing and building LivePerson’s native mobile SDK.

Mobile SDK: Considerations & Best Practices

- 3. Yaron Karasik New York Greenwell Hi, I’m Yaron Karasik
- 5. What is a mobile SDK?
- 6. Why build a native Mobile SDK?
- 7. Offer a mobile specific service Make existing service or API easily usable
- 9. App developers are a well defined target market and business model
- 10. What do we need to consider when building a SDK?
- 11. How much time do you have to hook the developer?
- 13. What’s the easiest way for a developer to solve an SDK related issue?
- 16. Your SDK is a guest in its host app Creative Commons Image: Liz Mc https://www.flickr.com/photos/11638547@N00/3827808607
- 17. Minimum use of resources Easy to integrate and use Maximum compatibility Provide your own UI?
- 18. Users know what the app is doing
- 19. Users know what the app is doing
- 20. Yaron Karasik Don’t kill the battery
- 21. Yaron Karasik Be thrifty with cellular data
- 22. Not real time? Batch requests
- 23. Real time? Use mobile optimized transport and API
- 25. Keep your payloads as small as possible
- 26. Memory - Allocations & Leaks
- 27. Performance
- 28. Instruments
- 29. Automated Build Process and Testing Don’t crash the host app
- 30. Never ask the user for permissions..
- 31. ..but definitely use them if permission has been given Class $CLLocationManager = NSClassFromString(@"CLLocationManager"); if ([CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied) {! ..! }!
- 33. Again, users know what the app is doing..
- 34. Notifications Push requires server side support and developer trust
- 35. Notifications Local is very useful if already enabled by developer
- 36. App Size
- 37. Local Storage & Security • Don’t use local storage it you don’t have to • If you do, take good care of app data • Encrypt sensitive information • Purge it when you’re done • Use SSL for all networking
- 38. Should I use open source code in an SDK?
- 42. When will the developer upgrade the SDK?
- 43. Much later than you’d like So design your APIs for the long run
- 44. Make it easy to integrate and use
- 45. Instant onboarding Free tier (or trial)
- 46. Interactive docs are cool
- 48. Use CocoaPods.. platform :ios, '7.0'! ! pod 'AFNetworking', '~> 2.1'! pod 'Reachability'! pod 'LivePerson', '~> 1.5.448'! pod 'SocketRocket', '= 0.3.1-beta2'
- 49. ..or a minimum integration flow 1. Add required frameworks 2. Add SDK
- 50. Simple SDK Launch [[SDKManager shared] initWithAppId:@“XYZ-ABC”];
- 51. Developer Logs EcoTest[2051:66030] [LPMobile//info] Loaded. #ios #info! ! EcoTest[2051:66030] [LPMobile// warning] The server has reported an error with your app. This may be caused by a bad configuration - Please contact mobile@liveperson.com for assistance. #ios #warning
- 52. Smart callbacks and event reporting Notifications BlocksDelegates
- 53. Configuration - Server or Client side?
- 54. Help the developer keep the SDK updated Cocoapods + Github
- 55. Should your SDK include UI?
- 57. Provide UI friendly API, allow developer to use their own UI Plan A
- 58. Provide a view controller for the developer to present Plan B
- 59. Implement your own UI, automatically integrate with host Plan C
- 61. Custom Branding
- 64. What about assets? • Use flat design when you can • PNG crush required assets • Consider downloading and caching • Download bundle on first launch
- 66. Thank You! We are hiring
