👀 Want to see a preview of what's coming up in #JetpackCompose? We heard you that debugging shared elements is tricky. In 1.11.0-alpha03, a new composable LookaheadAnimationVisualDebugging was added. Wrap your SharedTransitionLayout to add visual cues to track down those hard to debug issues. 🐛⤵️

I've converted my side project to Navigation 3 (or at least, a similar close fork of Navigation 3), which you can try out on the web here! alex.vanyo.dev/composelife Two more complex scene ideas I've been playing around with: A SceneStrategy wrapping another SceneStrategy, and derived entry lists.

A small change that flew under the radar for me for #JetpackCompose: calling setContent in a test more than once doesn't crash now! It's still a bit awkward to test Activity recreation, but the workaround is a lot easier now: issuetracker.google.com/271226817#co...

A response to the section on "How Can I Determine the Size and Position of Descendants of Peers?" Using onGloballyPositioned (or onSizeChanged, or similar modifiers) like this is a quick way to get yourself into trouble with layouts that take multiple frames to resolve that can flash or look janky.

I'm excited to be speaking at #DroidconNYC next Thursday, hope to see you there! I'll be covering how to handle configuration changes in Compose, and specifically trying to answer the question of what you should put in android:configChanges and - probably more importantly - why. #AndroidDev

Alex Vanyo @vanyo.dev · 29/05/2025

Thinking about configuration changes isn't optional. Imagine a website trying to prevent the browser window from being resized or breaking when it does. Android apps can't disable configuration changes and need to react to them correctly without losing state using the tools available.

Scenes! If there's only one concept to call out for Navigation 3, it's scenes. The abstraction layer allows showing multiple panes at a time, and in different ways. It's the integration hook that integrates Navigation3 with ListDetailPaneScaffold in a flexible, satisfying way.

runComposeUiTest has a nice change in #JetpackCompose 1.9.0-alpha01 - the test body block now suspends! So you no longer have to do a nested runComposeUiTest { runTest { /* suspending test code */ } }, which could be funky since runComposeUiTest had an internal runTest before that wasn't exposed.

Alex Vanyo @vanyo.dev · 28/04/2025

A small but extremely useful foundational API added in #JetpackCompose 1.8: LocalWindowInfo.current.containerSize It's the best way to get the size of the window, which should form the basis for any breakpoint logic for top-level layouts like window size classes. #AndroidDev

So the idea is with strong skipping, === is an extremely fast check. Imagine you have a lazy list and an array with a couple of hundred items, 3 on screen. Depending on the cost of equals, it's faster to let that higher level recomposition happen with ===.

UI that isn't tested is UI that can break. There are Compose techniques for each part of testing - quick verification when iterating, and automating both visual tests and behavior tests. And coming in Compose 1.8, don't miss the new DeviceConfigurationOverride.WindowInsets for testing insets!

Android 16 will have some big changes around restricting orientation and aspect ratio by respecting the user's preferred orientation in more cases. Apps can no longer rely on assuming they have a specific aspect ratio to render in. For more details: android-developers.googleblog.com/2025/01/orie...

After figuring out how to make the coordinates work, it's so satisfying to use a live-updating drag and drop that previews where the dropped content will go.

Today was a git cleaning day. I found local git branches I had that don't have an upstream, and then tried to figure out what I was doing and why. Mostly random experiments or old intermediate WIP that I didn't clean up, but there were also some neat things I completely forgot I started!

Frustrating experience but funny once I realized what was happening: I copied a line of code in a browser, switched desktops to Android Studio, and pasted... but it pasted an old thing! Copy and paste in AS to test... that works fine. Go back to browser, copy, paste in AS, and it still doesn't work.

Annoyed with merge conflicts when updating versions in libs.versions.toml? If you add a "#libraryName" above each version entry, you can avoid the merge conflicts caused by adjacent lines being updated independently since each simple version bump will have an unchanged line in-between another.

A libs.versions.toml file with library name tags for each version

Here's a fun #AndroidDev architecture design problem: Implement a slider that edits state that is stored on disk. I think working through this task can reveal a lot of insight for why building great UI around asynchronous tasks can inherently be tricky and how tradeoffs are necessary.
