1. Ahmad Arif Faizin Curriculum Developer - Dicoding Indonesia Tren Pengembangan Aplikasi Android di 2021
2. Tren 2021?
3. “Classic” Android Development
4. Previously… Language Java Programming Language • Base of Android Framework • Large developer base • Existing libraries, patterns, best practice • Robust/automatic memory management • Still good.. but verbose
5. Previously… Tools Eclipse + ADT • Familiar developer experience • Integration of new sub-tool into IDE • Difficult to customize • Sub-tools tended to have inconsistent UI • Core IDE not being actively improved
6. Previously… APIs • Android Support • AppCompat • Complicated ◦ Lifecycle ◦ Storage (SQLite) ◦ Navigation (manual)
7. Previously… Distribution APK • Zipped for your convenience • More Configurations? ◦ More APKs! ◦ Or bigger APKs!
8. Answer: Modern Android Development
9. Modern Android Development? Development tools, APIs, language, and distribution technologies recommended by the Android team to help developers be productive and create better apps that run across billions of devices.
11. Modern… Language
12. Kotlin Benefit • Expressive and Concise • Safety • Interoperability • Structured Concurrency with Coroutine • Speed
13. Kotlin Uptake • 20% less likely to crash • 60% of Pro Android Developers use Kotlin • 70%+ of Top 1000 Apps contain Kotlin code Source : Google Internal Data, May 2020
15. Kotlin-KTX • Without KTX • With KTX val viewModel = ViewModelProvider(this).get(MyViewModel::class.java) val viewModel by viewModels<MyViewModel>()
16. New Kotlin Highlight • Kotlin Gradle DSL • Kotlin Live-Template • Asynctask deprecated (Use Coroutines / Executors) • Coroutine Flow • Trailing Comma • SharedFlow and StateFLow • Kotlin Synthetic deprecated (Use View Binding) • Kotlin Multi-platform Mobile
17. Modern… Tools
18. Android Studio Features • Intelligent code editor + Code Template • Visual Layout Editor + Motion Editor • Database Inspector • Layout Inspector • Navigation Editor • Performance Profiler • APK Analyzer
19. Android Studio Benefits • Powerful code refactoring • Extensible UI for future tools • Core+plugins being actively developed • Tight integration with Kotlin, gradle • Lint checks, quick fixes • Integration with existing and new API (Navigation, layouts, data binding, Room)
20. Modern… APIs
21. Android Jetpack Benefits • Accelerate development • Eliminate boilerplate code • Build high quality, robust app
22. Android Architecture Components
23. Android Jetpack Highlight • Architecture Components ◦ Room + ViewModel + LiveData • Material Design Components • Paging • Navigation • WorkManager for schedule deferred job • Dagger Hilt for Dependency Injection • Jetpack Compose
24. Jetpack Compose
25. Modern… Distribution
26. Android App Bundles • Official publishing format and a more efficient way to build and release your app. • Easily deliver a great experience in a smaller app size which can improve install success and reduce uninstalls. • In second half of 2021, you must use AAB for upload to Google Play, instead APK.
27. Dynamic Delivery with AAB
28. AAB Uptake • Over 600,000 apps and games currently use the app bundle in production, representing over 40% of all releases on Google Play • 20% average size saving vs universal APK • Up to 11% increase in installs from size savings Source: Google I/O 19
