4. BACKGROUND OF ANDROID UI
5. ANCIENT WAYS FOR TACKLING UI VIEWS:
6. Jetpack Compose Android’s recommended modern toolkit for building native UI. It simplifies and accelerates UI development on Android. Use declarative approach.
7. What’s new in Android’s modern tooling for building native UI?
8. Pager Component •Horizontal Pager •Vertical Pager
9. Difference XML vs Compose Pager Component
10. Flow Row & Flow Column
11. Flow Row & Flow Column
12. Compose for TV (AndroidX TV library) • Immersive list • Corousel
13. Immersive List Carousel Navigation Navigation Drawer S hades of Compose for TV
14. Jetpack Glance (AndroidX library) Develop widgets optimized for Android phone, tablet, and foldable home screens using Jetpack Compose. • Interactive widgets • Responsive widgets • Faster UI Iteration
15. Adaptive UI with Material 3 Components • Window Size Classes for canonical layout support. • Large screen optimization layout guidance. • Navigation Components for all screen sizes
16. What's new in Android? Android Enhancement How android architecture, privacy policies, and internal changes occuring?
17. Approximate Location Camera/Mic Toggles Partial Media Access Photo Picker without permissions Android Enhancement Privacy & Security
18. Reduce reliance on passwords with passkey Uni ed sign-in Android Enhancement
19. Cross Platform Apps with native code Kotlin Multiplatform Why it is different from other hybrid frameworks and how we can start?
20. Hybrid Applications platforms Kotlin Multiplatform
21. How it Started? Kotlin Multiplatform KMM – Deals with mobile platform. KMP - Deals for all platform, including iOS, Android, and Web
22. How is it Changing? Kotlin Multiplatform We are deprecating the “Kotlin Multiplatform Mobile” (KMM) product name. From now on, “Kotlin Multiplatform” (KMP) is the preferred term when referring to the Kotlin technology for sharing code across different platforms, regardless of the combination of targets being discussed. On July 31, 2023
23. How it Evolved? Kotlin Multiplatform
24. Understanding KMP project structure Kotlin Multiplatform
25. Actual / Expect – under the hood Kotlin Multiplatform • Implementation that all OS would do it by themselves. • It is like a lateint modifier, means promise that I would do expect implementation at all OS side. • Expect is like an interface in Kotlin and protocol in Swift.
26. Actual / Expect – contd.. Kotlin Multiplatform Shared folder: CommonMain Shared folder: AndroidMain Shared folder: iOSMain
27. Challenges & Starting Strategies Kotlin Multiplatform
28. Network Operations Kotlin Multiplatform Retrofit KTOR • Create asynchronous client and server applications. • Kotlin Serialization – works with Ktor AlamoFire/AFNetworking Challenges: • Coroutine is bundled with Ktor to do asynchronous calls • Coroutine or suspend function • Use callback to deal Link: https://kotlinlang.org/docs/native-objc-interop.html#mappings

32. Dependency Injection Kotlin Multiplatform Dagger/Hilt Koin • A lightweight dependency injection framework. • Declarative library, DSL. • Use modules for declare dependencies. • Use single{..}, singleOf{..} & factory{..}, factoryOf{..} Swinject/Manual
33. Cross Platform Apps with Jetpack Compose Compose Multiplatform How compose UI is compatible with every platform?
