Project mention: Wondering what component to use and how to style it for this effect?...the live chat part | reddit.com/r/AndroidStudio | 2022-07-19
What part of the chat exactly are you asking about? There are multiple things at play here. E.g For the bottom sheet, you can check out this library: https://github.com/afollestad/material-dialogs/blob/main/documentation/BOTTOMSHEETS.md. For the elevation/shadow effect, check this out: https://proandroiddev.com/statelistanimator-a-powerful-little-tool-for-elevation-animation-4b31781e98a0

Project mention: Reactive Backend Applications with Spring Boot, Kotlin and Coroutines (Part 2) | dev.to | 2023-01-10
Kotlin has coroutines that are supported by the language and implemented by a library (the implementation remains platform-dependent): kotlinx.coroutines and a sandbox environment is available here to try it out.

compose-jb
Compose Multiplatform, a modern UI framework for Kotlin that makes building performant and beautiful user interfaces easy and enjoyable.
Project mention: Already experienced with Flutter. Best courses to learn Kotlin Android development? | reddit.com/r/Kotlin | 2023-01-17I'd also recommend taking a look at the Compose Multiplatform repo. Compose is written in a way that the Kotlin team can partner with the Android team to take the Android code base and make it run on iOS, Desktop, and Web as well. iOS and Web are still in early preview, but we should see an alpha or a beta later this year.

For people curious, the NowInAndroid repo does do this "build-logic" Gradle structure. I used that as a reference to apply this in our repo and it's been an amazing experience. Never have I had such a simple way to introduce new modules to the codebase. Effortless.

Project mention: Why tools have Kotlin native to work with bytes? | reddit.com/r/Kotlin | 2022-12-03
Yeah Kotlin's own standard library is a lot smaller than Java's currently so you'll need to use something third-party for this. Okio is a popular option https://square.github.io/okio/ it has a Buffer type which is pretty similar to Java's ByteBuffer

koin
Koin - a pragmatic lightweight dependency injection framework for Kotlin & Kotlin Multiplatform
New modules allow you to easily build KVision apps with the Ballast opinionated application state management framework. You can see how Ballast (together with Koin) can help you design your application architecture in the new todomvc-ballast example.

Project mention: setResult and finish don't work inside any Coroutine Scope. Possible reasons? | reddit.com/r/androiddev | 2022-07-14
We use the Compressor library in our app. I upgraded it to V3 today, and that requires that the compression code be run inside a Coroutine Scope.

Pokedex
🗡️ Pokedex demonstrates modern Android development with Hilt, Material Motion, Coroutines, Flow, Jetpack (Room, ViewModel) based on MVVM architecture.
For example this one is decent https://github.com/skydoves/Pokedex

Anki-Android
AnkiDroid: Anki flashcards on Android. Your secret trick to achieve superhuman information retention.
Project mention: Curious about this: why are Anki collection packages (.colpkg) exported from AnkiDroid smaller than those exported from the desktop application? Both exports included media. The desktop application was created by importing the AnkiDroid export and then exporting, so all decks and cards are identical | reddit.com/r/Anki | 2023-01-30 -

android-showcase
💎 Android application following best practices: Kotlin, Coroutines, JetPack, Clean Architecture, Feature Modules, Tests, MVVM, DI, Static Analysis...
Project mention: API call from ViewModel constructor or dedicated public method | reddit.com/r/androiddev | 2022-12-14In a typical app that fetches data from API (without using Flows), do you prefer to fetch data in a ViewModel constructor (init) or have a dedicated public method called from view (e.g. onViewCreated -> viewModel.onEnter). Here is example of the second approach from the Showcase app (see the onEnter method): https://github.com/igorwojda/android-showcase/blob/main/feature_album/src/main/kotlin/com/igorwojda/showcase/feature/album/presentation/screen/albumlist/AlbumListViewModel.kt

tivi
Tivi is a work-in-progress TV show tracking Android app, which connects to Trakt.tv. It is still in its early stages of development and currently only contains two pieces of UI. It is under heavy development.
Project mention: Modern ways to expose Retrofit network progress and errors to a ViewModel? | reddit.com/r/androiddev | 2022-12-22Thanks I think what's confusing is that UI events are recommended to be modeled as Flows, which I guess is why Tivi uses Flows for even the simplest actions, but it does a lot of very fancy things. Most repository interactions seem to have an entire class extending an Interactor (e.g.) which catches and emits errors, progress and handles timeouts and does all that crazy queuing stuff with UI "messages" Flow
