Talk for Droidcon Vienna 2018.

1. What the hype?
ŽELJKO PLESAC, TECHNICAL DIRECTOR

2. We're an independent
design & development
agency.

4. CLIENTS FROM ALL OVER THE WORLD
20 COUNTRIES
150+ CLIENTS
500+ PROJECTS

8. IT peer pressure

9. This framework will totally
solve all of your problems.
- EVERY DEVELOPER EVER

11. HYPE DRIVEN DEVELOPMENT

12. When decision about technology is
based on hype, not on analytical data.

13. 4 HDD TYPES
(BY MAREK KIREJCZYK)

14. Reddit driven development

15. Conference driven development

16. Loudest guy driven development

17. Library/framework driven development

18. YAFS
Yet Another Framework Syndrome

20. HDD LIFECYCLE

22. Risks
No additional gain to the product
Recruitment problems
Deprecated/unusable
Increased development costs

23. Advantages
New solutions to old problems
Increased code quality
Decreased development costs
Developer happiness

24. HOW DOES THIS ALL CONNECT WITH
ANDROID DEVELOPMENT?

25. CASE STUDIES

26. CASE STUDY #1
Kotlin

27. KOTLIN
Statically typed programming language, interoperable with Java and Android
Introduced in 2011.
At Google I/O 2017, Google announced first-class support for Kotlin
on Android.

28. Solution to every
problem in
Android
development.

29. INTERESTS OVER TIME

30. KOTLIN IN 2018
Adoption rates have exploded
Developers love it
Superseded Java in Android development

31. CASE STUDY #2
Realm

32. REALM
Open-source object database management system, replacement for SQLite
and Core Data.
Introduced in 2014.

33. At one point, it
looked as
everybody was
going Realm.

34. INTERESTS OVER TIME

35. REALM IN 2018
Large user base, but popularity is falling.
Some “controversial” implementation details.
Increased number of competitor tools (Room, Firebase).

36. CASE STUDY #3
RxJava

37. RX JAVA
Reactive Extensions for the JVM.
Toolbox for async work.
v1.0.0 released in 2014

38. Simple solution
for a complex
problem.

39. INTERESTS OVER TIME

40. RXJAVA IN 2018
Reactive(functional) programming is everywhere.
One of the most popular Android frameworks.
Influenced LiveData/MVVM.
Increased number of “moving away from” blog posts in favour of Kotlin
Corutines.

41. CASE STUDY #4
Instant Run

42. INSTANT RUN
Reduces the time it takes to update your app with code and resource
changes.
Introduced with Android Studio 2.0

43. Speed up the
development
process.

44. INTERESTS OVER TIME

45. INSTANT RUN IN 2018
Lots of bugs, still not a polished product.
Nobody likes it.
No competitors (JRebel has deprecated Android support).
No news.
No clear future.

46. CASE STUDY #5
EventBus

47. EVENT BUS
Open-source library for Android and Java using the publisher/
subscriber pattern for loose coupling.
Introduced in 2012.

48. Simplify
communication
between parts of
a system.

49. INTERESTS OVER TIME

50. EVENTBUS IN 2018
Polarised response - half of the people adore it, half of the people are
disgusted by it.
Loosing in it’s popularity due to well defined architectural patterns (MVP/
MVVM).
Still, used in a large number of projects.

51. CASE STUDY #6
MVP/MVVM

52. MVP/MVVM
Model-view-presenter vs model - view - view model architectural approach.
Exploded in popularity together with Dagger2/jUnit tests.

53. “Way to go” for
organising the
code.

54. INTERESTS OVER TIME

55. MVP/MVVM IN 2018
MVP was #1 until Google I/0 2017 and Android Components introduction.
MVVM is quickly gaining on popularity.
MVVM has superseded MVP.

56. OTHER

57. Android Studio
jUnit tests
Espresso
Robolectric
React native
Jack toolchain
Lottie
Material design
…

58. BIGGEST HYPE IN ANDROID
DEVELOPENT OF 2018?

60. ROUNDUP.

61. Base you decisions on analytical data
and experiments, not current hype.

62. Always test the hype technology
before introducing it to your
development process.

63. Wrong technical decisions will haunt
you for a long time.

64. Hype in not a bad thing.

65. Always look for hype technologies.
