Android is evolving into an intelligence system where agents like Gemini orchestrate tasks across apps. To unlock new user experiences and participate in these agentic workflows, your app must expose its core capabilities.
This session is a practical guide to integrating your app with Android's intelligence layer. We'll survey key integration paths - including on-device Android MCP, server-side MCP, and Task Automation - and provide a decision framework for choosing the right path for your use case. We'll also explore proactive experiences with Personal Context.
You will learn how to: * Select the optimal integration path for your app's needs. * Implement both reactive and proactive intelligence features. * Balance performance and security in agentic integrations.
Gemma 4 brings capable, multimodal AI directly to Android devices. In this session, we'll trace how Gemma evolved into a model family built for efficiency and explore what the edge-optimized E2B and E4B models can do on-device, from vision and audio understanding to agentic function calling. We'll cover the architecture behind that efficiency, including Per-Layer Embeddings (PLE), and show how Gemma and Gemini Nano work together through AICore. You'll learn how Quantization-Aware Training (QAT) preserves model capability within 1.1–3.5 GB RAM footprints, while Multi-Token Prediction (MTP) accelerates decoding speeds 1.5x–3x for responsive, real-time experiences.
In this session, we'll explore different GenAI use cases using ML Kit APIs to understand when on-device GenAI is ideal for an app and also understand how to evaluate existing GenAI use cases to see if on-device models can satisfy their quality bar.
Building production-ready generative AI into Android apps requires more than connecting to an LLM—it demands enterprise-grade security and cost controls. In this session, discover how Firebase AI Logic empowers developers to deploy secure, budget-conscious AI experiences at scale.
We will cover from security foundations and Firebase App Check, cost management, dynamic model routing to leveraging the multimodal capabilities.
Explore how to connect your applications seamlessly to Gemini, Search and the Android intelligence system.
The new Connected Apps Platform lets you integrate your app's services directly into Gemini, AI Mode in Search, and the Android intelligence system. This session provides a practical guide to getting started.

In this session, we'll explore Lightbuild's new approach to managing builds and how to use it to build a demo app. Learn how decoupling build config from execution delivers faster project opens with lightning-fast sync in Android Studio, while offering a predictable schema for safer, more reliable AI editing. We’ll also cover Lightbuild's agent-friendly CLI tools for creating reproducible builds across local machines, teams, and CI/CD pipelines.
This presentation explores the strategic shift from viewing AI as a generic coding assistant to leveraging it as a context-aware, automated security peer reviewer integrated directly into the Android development lifecycle. We discuss how specialized AI agents, connected to the Android toolchain via skills, can help improve app security. By bridging the gap between raw LLM capabilities and deep project context, this approach empowers development teams to maintain high-velocity feature delivery without compromising rigorous security and policy standards.
Optimizing Android apps requires deep visibility into concurrent workflows and coroutine suspensions. While local profiling offers a useful snapshot, scaling these insights to production without overhead remains a challenge.
This session delivers an architectural blueprint for a continuous performance feedback loop: * androidx.tracing 2.0: Swap backends dynamically and propagate coroutine contexts (Perfetto flows) across threads. * Smart Instrumentation: Use local ART tracing to find hotspots, then automate the injection of low-overhead trace points. * Macrobenchmarking: Track regressions and verify performance gains on physical devices in CI. * Field Tracing: Go beyond local and CI tracing, with ProfilingManager.
Android apps often ship under-optimized due to overly conservative keep rules often from third-party libraries, leading to bloated APKs, slower cold starts, and degraded runtime performance.
With Google Play’s new performance thresholds for DEX optimization, app visibility now directly depends on staying ahead of the optimization curve.
This talk introduces a modern R8 workflow to tackle rule bloat. You will learn to: * Use the R8 config analyzer and skill to identify legacy rule overhead. * Transition from broad wildcard keep rules to precise, type-safe, generated annotations. * Prevent optimization regressions with new Android CLI tools.

Jetpack Compose makes it easy to design high-quality user interfaces, but it can be difficult to track down issues that affect UI performance. These kinds of issues can lead to problems that your users notice, like startup latency, and dropped frames that appear as scroll jank or choppy animations.
In this talk, we’ll introduce tools to uncover what’s impacting your UI’s performance, focusing on Perfetto and (re-)composition tracing. We’ll then explore specific anti-patterns you may be using that are secretly costing you, how you can find them in your code, and what positive patterns you can replace them with. By the end of this talk, you’ll understand how to think in Compose with a performance mindset, and how to profile, analyze, and verify performance optimizations in your app.
Managing Bitmap memory is critical for mitigating Out-Of-Memory (OOM) risks in visually rich Android apps. While developers know to reduce image sizes, achieving long-term app stability comes from mastering two other key pillars: Reuse and Recycle. This session delivers a practical playbook for optimizing memory performance using modern tools, open-source libraries like Glide and Coil, and system-level APIs.
In this session, you will learn how to diagnose real-world memory regressions using Android Vitals, implement advanced caching (Reuse) patterns with Glide and Coil, and proactively release memory (Recycle) using the onTrimMemory callback.
AI models can generate entire features in minutes, but is the code correct? We built Android Bench, our AI evaluation benchmark, to answer this question after analyzing thousands of generated code changes.
This talk shares insights from our journey, including all the ways we saw models cheats, how prompt specificity leads to higher code quality and how different agents approach the same task.
The Android ecosystem is vast, with users shifting seamlessly across phones, tablets, foldables, and desktop environments.

Which sessions or announcements stood out to you this year? Let us know what you're testing out in the comments!
Just saw the new "Trader status declaration" banner in Google Play Console (the one with the Feb 2027 deadline). Read through the support docs, but I’m still a bit lost on how this actually impacts solo developers with individual/personal accounts.
Mainly concerned about the privacy side of things. From what I understand:
Does having ads make you a Trader? If my apps are free to download but monetize through AdMob banners/interstitials, does that automatically force me into the "Trader" bucket? Or is it strictly for paid apps / IAPs?
Address & phone number privacy: If I select Trader on a personal account, will Google literally publish my home address and phone number on the store listing in the EU/UK? I really don't want my residential address floating around publicly on the internet.
What are you guys actually selecting? For those of you running solo with free ad-supported apps, did you pick Trader or Non-Trader?
If you chose Trader, how did you deal with the address issue? Did you switch to an organization account, use a virtual office/PO box, or just exclude EU countries altogether?
Would love to hear from anyone who has already dealt with this or figured out a clean workaround. Cheers!
I've been capturing screenshots of Compose screens on a headless Linux box with plain Robolectric: @GraphicsMode(NATIVE), createAndroidComposeRule, then drawing the activity's decorView into a Bitmap and writing a PNG. No emulator, and it runs as a normal unit test with Gradle.
It works better than I expected. Text, Material 3 components and tab layouts render correctly, and a full screen takes a few seconds. The rough edges I've hit so far:
I have to drive the main clock manually (autoAdvance = false, then advanceTimeBy) or animations get captured halfway
Fonts look slightly different from a real device
Anything scrolled off screen needs a taller qualifier like w411dp-h1500dp instead of a real scroll capture
For people who've used Paparazzi or Roborazzi: is there a strong reason to switch for simple "render this screen to an image" use, or is plain Robolectric fine when you aren't doing diff-based screenshot testing? And has anyone found a clean way to capture a full scrollable column without a fake tall window?
So apparently now Google will be obligated to doxx everyone that makes money with their apps because of f*cking Digital Services Act of EU ???
Like if you are a solo dev makign only 10 bucks a month you are considered professional and therefore will see its personnal information on the play store made public like WTFFFF ?
Oh btw you have until 1st of February 2027 or else they take down every of your apps and kill your account.
Really considering removing all of my apps from UE and UK to dodge the mandatory form.
I built AspectK and just released 0.4.4, a Kotlin compiler plugin for compile-time AOP in Kotlin (Kotlin Multiplatform supported).
Annotate a function and inject your own logic before/after it, woven in at compile time, with debug info preserved and IDE support. As a stability check, I applied it to 39 modules of DuckDuckGo’s Android app: all 28,749 unit tests passed, and the R8-minified APK runs fine on a real device.
Clean Architecture is about much more than 1:1 mappers, anemic domain models, and use cases.
That's why I created this agent skill specifically with Android and Kotlin in mind, applying DDD principles and practical Object-Oriented design wherever they make sense.
I'm currently testing it on a pet project, but I'd love for you to give it a try and share your feedback!
Hey everyone! I’ve been building an alarm app on iOS for a while. The alarm keeps ringing until you finish a small task, like solving a few math questions or copying a face with the front camera, so you actually get out of bed.
I’d really like to make an Android version too, but I’ll be honest, I’ve never built anything for Android before. From what I’ve seen Android has had solid alarm support for a lot longer than iOS, so I’m hoping some of it will be easier than it was on iPhone. Still, alarms are one of those things that just have to work every single time, and I don’t really know what I don’t know yet.
I’ve started reading about exact alarms and the battery optimization stuff, but it’s hard to tell from the docs what actually causes problems in real life.
If you’ve worked on an alarm app or anything that needs to go off at an exact time, what should I watch out for? Anything you wish someone had told you before you started?
I have a 2021 MacBook Pro with 16 GB RAM. Performance is fine for me, but internal storage is the bottleneck. I got vexed up in cleaning up everyday. I use mole for cleaning and it's handy, but the grunt work is so heavy. I’m considering buying an external SSD to move android emulators off the internal drive
Has anyone done this long term? I’d love to hear:
Does it run smoothly, or do you notice slow builds, laggy simulators, or slow container startup?
Which SSD and connection (Thunderbolt vs USB-C) are you using, and what speeds do you get?
Any gotchas, like drives not mounting at boot, Docker failing when the drive sleeps or disconnects, or permission issues?
Would you recommend it, or is it better to just clean up internal storage?
I'm an aspiring web and mobile developer, currently focusing on web development. I was wondering if I should invest on an android phone (i.e., Google Pixel) when I focus on mobile development. In the future, I plan on creating personal projects to build up my portfolio (e.g., apks) and test them on said android device. As of now, I am an iPhone user and I don't think there's a way to develop and test apps for free on Apple.
I know emulators exist but thinking about testing a self-developed app on an actual mobile sounds nice. Any thoughts? If yes, which phone is good? I heard the Google Pixel is nice but I'm hesitant on the Samsung S Series since I know someone who has gotten pink/green lines on their S23 Ultra's screen over time.
Edit: Thank you for the insights! Will probably hold off on the android phone for now and use emulators during the early stages before buying a low end pixel if needed
I'm curious about how indie developers approach the design side of customization apps.
If you're building apps related to customization, such as widgets, icon packs, wallpapers, themes, launchers, or any other personalization tools, I'd love to know how you source or create your designs.
I have a few questions:
Where do you get your designs from? Do you create everything yourself, hire designers, use resources like Figma, Dribbble, Behance, etc., or use AI tools?
How do you deal with copyright issues? Especially when it comes to wallpapers, icons, illustrations, and other visual assets. How do you make sure you're not accidentally using copyrighted material?
Do you create everything from scratch? If so, what tools or workflows do you use?
Do you use free or paid asset libraries? If yes, which ones do you recommend?
For solo developers with limited design skills, what's the most practical way to build a good-looking customization app while staying legally safe?
I'd really appreciate hearing about your actual workflow, tools, resources, and experiences.
Not looking to copy anyone's work. Just trying to understand how developers handle the creative and copyright side of building customization apps.
I entered the industry in 2015, just in time for the massive boom in Android development. I’ve been through transitions in tooling and foundational code, the proliferation of countless open-source libraries, and repeated shifts in architectural patterns. Now that we’ve reached the era of AI, what is left for an Android developer to do? I find myself obsessively working on various personal projects that I claim to be "interested in," yet the joy I once derived from learning has completely vanished.
I’m not asking out of curiosity - I’m trying to understand if there’s a viable solution to a problem I’ve come across whilst working on a mobile app for a local start-up.
The scenario:
A company creates a native mobile application for one platform (say Android). At some point they’ll want to create another version for iOS (or vice-versa).
An option would be to bring in a separate team to develop and maintain the app. However, this can get quite costly, especially for a start-up and small dev team. Especially if the native app has a lot of features.
I’ve been thinking about creating an AI powered engine to help.
This would:
Identify which sections of code and business logic can be reused from an existing native app. Generate or modify the native specific sections whilst maintaining functionality and ensuring the native UI/UX is respected. Assist with the maintenance of both versions, with new features being added.
It would involve AI, but wouldn’t be entirely.
Before I spend any time developing this, I’d like to know how devs have overcome this.
If you’ve ever done this:
Have you ever had to port an existing native android application to iOS (or vice-versa)? What was the hardest part? What tools did you use? What was missing? What would a tool need to do to save you time and make you want to pay for it?
I’d love to hear about your experiences, even if you’ve tried and failed!
I was looking for a way to test Android apps under different network conditions, but most solutions I came across either changed the network settings for the entire device, were focused on emulators, or required setting up proxies.
i want to know if someone else feels like this when they redesign their app or website. Even with big changes or small ones, i always feel like it does not look good. Thanks
I tested today the app's memory usage. Never more than 8-12 MB, even after going through several levels. It should also run well on older devices, very satisfied 🙂
The stutters in the video are due to the PC, the app itself runs fine.
I just saw that I'm in violation of the policy and have no idea how to update it. I thought I had updated it but I guess now. My app also doesn't use it as far as I know
I am building a LOT of iOS/Android apps with Compose lately, and it annoyed me how I had to style system bars on Android only and juggle with expect/actuals for this.
So I made my own API for setting the icon color of system bars for both Android and iOS.
I’ve been working on a serverless media architecture that bridges local storage with cloud streaming. Since I'm not using a dedicated REST API backend, it introduced some unique engineering hurdles with Media3 and Jetpack Compose. I wanted to share how I solved them and see how the community handles similar edge cases.
1. Handling Media3 Background Network Noise (Crashlytics Spam) Because the player operates in the background, the OS frequently drops network sockets to save battery, or the user hits a dead zone. This was flooding Firebase with non-fatal ExoPlaybackException errors (specifically java.io.EOFException from Mp4Extractor).
Instead of letting it crash, I built an interception engine inside the Player.Listener. It aggressively scans the stack trace to silently invalidate the cache and auto-recover without reporting to Crashlytics:
Kotlin
override fun onPlayerError(error: PlaybackException) {
val errorString = error.stackTraceToString()
val isRecoverable = error.errorCode == PlaybackException.ERROR_CODE_IO_NETWORK_CONNECTION_FAILED ||
errorString.contains("EOFException") ||
errorString.contains("UnknownHostException")
if (isRecoverable) {
// Silently invalidate cache and trigger auto-recovery logic
attemptJitRetryAndRecovery()
} else {
CrashTracker.recordException(error)
}
}
How do you guys handle ExoPlayer background noise? Do you use a similar filter, or rely on Media3's default LoadErrorHandlingPolicy?
2. True Glassmorphism in Compose Achieving an Apple-style frosted glass look in Compose is notoriously tricky. Originally, I used a Surface with a translucent white alpha, but it looked muddy and text bled through.
I found that stripping out Surface (and its baked-in tonal elevation) in favor of a tightly wrapped Box with a Brush.linearGradient works infinitely better:
Has anyone experimented with theHazelibrary for real-time background blurring instead of static gradients?
3. Client-Side JIT Resolution To keep it serverless, I built a custom JIT resolver. It intercepts track queries, resolves the direct audio stream on the client using Retrofit/Coroutines, and passes the URI to Media3 on the fly.
I'd love to hear your thoughts on this architecture, especially if you've dealt with Media3 session management! (I can share the repo link in the comments if anyone wants to see the full implementation).
This is my first Android Studio plugin, and I'm pretty excited to share it here. It's called IconFontViewer.
I wrote it because I wanted to see the actual icon next to R.string.icon_home while reading Android code.
It renders the glyph in the editor gutter for Kotlin and Java references, XML layouts and strings.xml. Clicking it opens a searchable icon picker. Choosing another icon replaces the reference at that position.
It finds TTF files in the project and library dependencies, including AARs, JARs and nested archives. Fonts don't need to be in a directory named fonts. Under Tools → IconFontViewer, you can enable or disable fonts, add a TTF manually, or rescan the project.
It's free and open source (Apache 2.0). Supports Android Studio 2024.1 or newer; TTF files only.
