This is a post in a series on how I tackled Nav3 concepts and wired things together. Dialogs are modeled as an overlay scene; the destination behind the screen must remain rendered. Right now, its lifecycle stays resumed. That creates a number of practical challenges and problems: The last issue caught me off guard. dropUnlessResumed … Read more
This is a post in a series on how I tackled Nav3 concepts and wired things together. I needed a sheet that can be closed by dragging it down – it surprised me a bit that the implementation isn’t that difficult. It uses the overlay scene concept and a few basic helpers from the Compose … Read more
This is a post in a series on how I tackled Nav3 concepts and wired things together. There is no Nav3 bottom sheet implementation yet, so this is a quick post on how to create a scene/scene strategy, including the latest “enhancement” from the (yet unreleased) 1.1.0-alpha04 version that fixes the missing animation when popping … Read more
We’re all happy about Navigation 3, right? But before we get more stability and recipes, I had to fix something in Navigation 2′ use case. This post is about a hack to get things working. If you know a better way, definitely reach out to me. The Problem I’m working on an app that will … Read more
Having a paginated stream of data can give you a bit of a headache. AndroidX provides its own paging library, which offers a lot of abstraction. However, I ultimately failed three times and started looking into what other options I had. My Issues with AndroidX.Paging All these issues ultimately stem from AndroidX.Paging’s very closed, strict … Read more
Many months have passed since I last wrote about Kotlin Flow: Domain Model’s StateFlow Sharing. So, let’s take a look at something related to Flow handling in a ViewModel. StateIn shortcut Usually, you want a StateFlow‘s state to survive a configuration change. AndroidX’s default time limit is 5 seconds — but only if it’s subscribed. … Read more
You may have heard that Jetpack Navigation has a new API for type-safe navigation. This new official solution brings navigation with a “destination object” instead of simple manual URL building. Previously, I developed kiwicom/navigation-compose-typed library that did the same and was an inspiration for the official solution. The official solution makes navigation easier than before, … Read more
This blog post is a repost from code.kiwi.com. Newly, there is a meetup talk about Navigation Compose Typed library. Jetpack Navigation Compose is the Jetpack Navigation library enhanced for usage in Compose. But the actual “enhancement” is a bit limited and different from the View-based navigation. Most importantly, there are no SafeArgs — a type-safe … Read more
Android end-to-end UI testing is not that difficult, but we have observed that the official API/tooling doesn’t scale much if you have a big app. “Page Object” is a design pattern abstraction over a particular screen: it provides access to read the screen’s data and provides an API to interact with the screen. You may … Read more
Our Kiwi.com app is quite old and vast. It is in development for about 7 years; each year we’re adding more features and code, each year the app is being worked on by more developers. We evolved to a custom back-aware logic in our activities and fragments. Basically, back press was handled in the activity … Read more
