I Tried Using Claude to Build an Android App. Here's What Happened.

Everyone in the developer community is trying to use Claude to build apps right now. Anthropic's model is, by most credible benchmarks, the best AI assistant available for coding tasks in 2026. It writes clean code, explains complex concepts clearly, and reasons through problems in a way that genuinely impresses engineers who've been writing software for decades.

So naturally, the question comes up constantly: can I use Claude to build a native Android app? Not a web app wrapped in a WebView. Not React Native. A real, native Kotlin/Compose Android app — with AdMob ads and RevenueCat subscriptions — that I can ship to the Play Store.

We tested this thoroughly. Here's the honest answer.

What Claude Can Do Well

Let's start with where Claude genuinely shines, because this isn't a hit piece. Claude is an exceptionally capable model, and there's a lot it handles impressively for Android development.

Writing individual Kotlin functions: Claude writes idiomatic Kotlin. Ask it to implement a coroutine-based network call, a Room database query, or a custom Compose component, and you'll get clean, well-structured code. It understands modern Kotlin idioms — extension functions, sealed classes, data classes, flow operators — and uses them correctly. This is genuinely excellent.

Explaining Gradle concepts: Gradle is notoriously opaque. Ask Claude to explain the difference between implementation and api dependency configurations, or why your AGP version conflicts with your Kotlin version, and you'll get a clear, accurate explanation. For developers learning Android, this alone has real value.

Generating ViewModel boilerplate and Room queries: The Android architecture components — ViewModel, LiveData, StateFlow, Room — involve a lot of repetitive boilerplate. Claude handles this competently. Ask it to generate a ViewModel for a specific feature, a DAO interface for a given entity, or a Compose UI that consumes a StateFlow, and the output is solid.

Debugging specific errors when you paste them in: This is probably where Claude adds the most value in practice. Paste in a Gradle build error, a Compose runtime exception, or a cryptic coroutine stack trace, and Claude will usually identify the issue correctly. It's not infallible, but it's substantially better than searching Stack Overflow for an exact match.

Where It Falls Apart

Here's where the real limitations start to show — and they're not small limitations. They're fundamental ones.

No persistent project context. Every conversation with Claude starts fresh. Claude doesn't know your project structure, your existing Gradle config, which libraries you've already added, or what architecture decisions you've already made. You can paste context in at the start of each session, but this is error-prone and impractical for a real project of any complexity. The moment your project has more than a handful of files, Claude is flying blind.

This creates a compounding problem. Paste in your build.gradle.kts and ask Claude to add a library? It'll suggest an addition that may conflict with a dependency you added three sessions ago that you forgot to mention. There's no project memory. Every interaction is a fresh slate.

Gradle dependency conflicts. Even when you do paste in your build files, Claude can't fully reason about the entire transitive dependency graph. It might suggest adding a library version that conflicts with another dependency several layers deep. These conflicts produce build errors that are genuinely hard to diagnose if you don't have deep Android experience — and they're exactly the kind of problem Claude is supposed to help you avoid.

AdMob setup. Claude can write the AdMob integration code. It knows how to initialize the Mobile Ads SDK, create a banner ad composable, implement rewarded interstitials. But that's maybe 20% of what "getting AdMob working" actually requires. The other 80% is manual work Claude has zero access to: creating your AdMob account, generating ad unit IDs, configuring test devices, implementing the GDPR UMP consent flow (which is required for EU users and changes periodically), and handling mediation if you want to maximize eCPM. Claude can point you at the documentation. It cannot do any of it for you.

RevenueCat subscriptions. Same pattern. Claude can write the purchase flow code. It can show you how to call the RevenueCat SDK to initiate a purchase and check entitlements. But configuring your RevenueCat dashboard, connecting it to your Google Play Developer account, setting up products in the Play Console, mapping entitlements, and handling restore purchases across device reinstalls? All manual. All on you. All requiring multiple accounts, multiple dashboards, and hours of configuration work that code generation does nothing to address.

Play Store compliance. The data safety form alone can take a skilled developer hours to complete accurately. You need to declare every data type your app collects, how it's used, and whether it's shared with third parties. Get this wrong and your app gets rejected. Claude has no access to the Play Console and no knowledge of your specific app's data practices — it can only offer generic guidance. The same applies to target SDK requirements, app signing, and Google Play policy compliance, all of which shift regularly.

The "almost works" problem. This one is insidious. Claude generates code that looks correct, compiles without errors, and then behaves subtly wrong at runtime. Common examples: incorrect lifecycle handling in Compose (subscribing to a StateFlow in a way that causes memory leaks), threading issues with coroutines (calling a suspend function from a context that causes ANRs on certain devices), or state restoration bugs after process death. These bugs don't show up in a quick demo. They show up in production, in edge cases, on devices you don't own. Finding them requires Android expertise that, if you had it, you probably wouldn't be relying entirely on Claude in the first place.

Claude Code Helps — But Only If You're a Developer

Claude Code — Anthropic's agentic coding tool — is a meaningful upgrade over chat-based Claude for real development work. Instead of pasting code back and forth, Claude Code can read and edit your actual codebase. It can see your project structure, understand relationships between files, and make coordinated changes across multiple files at once.

For Android developers, this closes some real gaps. Claude Code can understand that you've already added a specific Gradle dependency and avoid suggesting a conflicting version. It can read your existing ViewModel and generate a complementary one that follows the same patterns. It can navigate your entire Compose component tree when making changes rather than operating on a single isolated snippet.

But here's the honest limitation: Claude Code still requires you to be an Android developer. You need Android Studio installed and working. You need Gradle configured correctly to begin with. You need to understand what Claude Code is doing when it edits your files — because it will make mistakes, and if you can't review its changes critically, you'll end up with a codebase you can't maintain or debug.

Claude Code is a genuine 10x multiplier for an experienced Android engineer. It is not a solution for someone who doesn't know what a ViewModel is.

The Honest Verdict

Here's the straight answer, without hedging.

If you're an experienced Android developer: Claude (and Claude Code in particular) will meaningfully accelerate your work. Writing boilerplate, debugging errors, understanding unfamiliar APIs, generating test cases — all of these tasks go faster with Claude. It's a genuine 10x multiplier if you know how to use it. You can cut development time roughly in half on feature work.

If you're not an Android developer: Claude will get you approximately 60% of the way to a working app. The code will look right. It might even compile. Then you'll hit a Gradle error you can't diagnose, or an AdMob integration that requires account-level configuration you don't understand, or a Play Store rejection for a data safety form you filled out wrong. The last 40% is where all the hard Android-specific knowledge lives — and Claude, impressive as it is, cannot replace that knowledge for someone who doesn't have it.

The 60/40 split is the key insight here. The 60% that Claude handles — the actual Kotlin code — is the part that's visible and legible to non-developers. It looks like progress. The 40% that's left — build configuration, monetization wiring, Play Store compliance — is largely invisible until you hit it, and when you hit it, it's a wall.

What Would Actually Solve This

The genuine gap in the market isn't a better code completion model. It's a tool that handles the entire stack — not just code generation, but build configuration, monetization wiring, and Play Store compliance — without requiring the user to understand any of it.

What that looks like in practice: you describe the app you want in plain language. The system generates native Kotlin/Compose code, resolves all Gradle dependencies without conflicts, wires AdMob and RevenueCat in from the ground up (not bolted on afterward), produces a Play Store-compliant APK, and does all of this without requiring you to touch Android Studio, understand Gradle, or configure a single external dashboard.

That's what we're building with Vixo. Genuinely native Kotlin and Compose — not React Native, not a web wrapper. AdMob and RevenueCat integrated at generation time, not as an afterthought. Under 10 minutes from prompt to working APK. Waitlist is open now, with 50% off for the first 500 signups in their first two weeks after launch.

Claude is outstanding at what it does. It's just solving a different problem for a different person than the one who needs an app compiler that handles everything end to end.

Claude vs. Claude Code vs. Android Studio + Gemini vs. Vixo

The table makes the picture clear. Claude and Claude Code are exceptional tools for developers who already know Android. Gemini inside Android Studio is useful for the same audience. None of these tools are aimed at the person who has an app idea but isn't a mobile developer — and that's the majority of people who want to build an Android app.
