How long does Android app development take?

A focused MVP with 4 to 6 core features typically takes 3 to 4 months with a dedicated team. A full-featured Android app with complex integrations, enterprise security, and support for a wide device range usually takes 6 to 12 months. The timeline is determined by scope, not by how fast you want it.

Should I build for Android only or both Android and iOS?

It depends on your audience. If your users are primarily in Europe, Asia, or Latin America, Android-first makes sense because market share exceeds 70%. If you are targeting the US or premium consumer segments, iOS may be the priority. Many founders launch on one platform first, validate, and then ex

Do I own the code and Google Play Store account after the project?

Yes. Every client receives full ownership of the source code, the Google Play Console account, infrastructure configuration, and all associated intellectual property. This is written into our contracts from the start. We also provide full documentation and handoff sessions.

What is the difference between Kotlin and Java for Android?

Kotlin is Google's recommended language for new Android projects. It requires 30 to 40% less code, has built-in null safety (preventing the most common Android crash type), and all new Android libraries are Kotlin-first. Java is still used in legacy projects. For new builds, we recommend Kotlin.

What tech stack do you use for Android app development?

We use Kotlin with Jetpack Compose for modern UI, following MVVM or Clean Architecture patterns. For backend we typically use Node.js or Python with PostgreSQL, hosted on AWS or Google Cloud. For push notifications and analytics we use Firebase. If you have an existing stack, we adapt.

Can you take over an Android project that another team started?

Yes. The first step is a codebase audit, which takes 3 to 5 days. We review the architecture, code quality, test coverage, and technical debt. We are honest about what we find. Sometimes a partial rebuild is cheaper than continuing with a broken foundation. We will tell you if that is the case.

How do you handle Android device fragmentation?

We test on real physical devices, not just emulators. Our QA process covers Samsung, Xiaomi, OnePlus, and Pixel devices across multiple screen sizes and OS versions. We build responsive layouts that adapt gracefully and use Google's compatibility libraries to maintain consistent behaviour across And

What happens after the Android app launches?

Launch is the beginning. After go-live we offer support retainers covering bug fixes, OS compatibility updates (new Android versions drop annually), security patches, and iterative feature development. We also offer structured sprint packages for monthly feature shipping based on user feedback.

Can you build an Android app with AI or machine learning features?

Yes. We have built Android apps with on-device ML using TensorFlow Lite, cloud-based AI via OpenAI and Google Vertex AI, image recognition, natural language processing, and recommendation engines. The key is knowing when AI genuinely solves a user problem versus when it is added for show. We help yo

Executive Summary

Android app development typically costs between $40,000 and $200,000 depending on complexity, features, and team size. A focused MVP can be delivered in 3 to 4 months. Full-scale apps with integrations take 6 to 12 months. The biggest cost driver is scope.

Language & Architecture

Kotlin vs Java: Which Language for Your Android App

Google officially recommends Kotlin as the preferred language for Android development. But Java is still widely used, especially in legacy codebases and enterprise environments. For most new Android projects, Kotlin is recommended. But if you have an existing Java codebase, your team works with what you have and can incrementally migrate to Kotlin where it makes sense.

Kotlin requires 30 to 40% less code, has built-in null safety, and all new Android libraries are Kotlin-first
Java is still supported for legacy projects and enterprise systems with existing Java infrastructure
100% interoperability between Kotlin and Java means both can be used in the same project

UI/UX & Fragmentation

Material Design and Device Compatibility

Android users expect apps to feel native. That means following Google's Material Design 3 guidelines for navigation, typography, colour, and motion. There are over 24,000 distinct Android device models in active use. Screen sizes range from 4 inches to foldable displays. OS versions span from Android 10 to Android 15.

Jetpack Compose for modern, declarative UI or XML layouts for projects requiring broader compatibility
Testing across real devices including Samsung, Xiaomi, OnePlus, and Pixel across multiple screen sizes
Responsive layouts that adapt gracefully using Google's compatibility libraries across Android versions

Security & Submission

Google Play Store and Security Compliance

Google has tightened its review process significantly. New apps face stricter quality checks, and Google removed over a million apps from the Play Store in 2024 alone as part of their quality enforcement push. If you are handling personal data or operating in a regulated industry, security is non-negotiable.

Full Google Play submission including store listing optimisation, screenshots, privacy policy, and data safety declarations
Encrypted storage, certificate pinning, ProGuard/R8 code obfuscation, and GDPR-compliant data handling

The Real Impact

Why It Matters

If you are launching to your first 10,000 users, pitching to investors, or trying to win enterprise contracts, the quality of your Android app is on display every single day. An app that crashes on Samsung devices, drains battery in the background, or gets rejected from the Play Store does not just lose downloads. It costs you ratings, referrals, and credibility. And Android users are less forgiving than you think. The average Play Store rating for apps that retain users past day 30 is 4.5 stars. Drop below 4.0 and your organic discovery drops off a cliff. The founders we work with who get the most from the engagement are the ones who come in with a clear problem, a defined audience, and a willingness to cut features that do not serve the first version. The ones who struggle are the ones who want to build for every device from day one with 30 features and a fixed deadline. Be honest with yourself about which you are. Android app development is not a one-time project. It is the start of a product that needs to evolve with every new OS version, every new device form factor, and every shift in user expectations. Choosing the right technical partner at the start saves you years of headaches.

Our Process

How we turn ideas into reality.

Discovery and Scoping

Your users, use cases, and revenue model are mapped before writing a line of code. This phase saves months of rework and prevents the scope creep that kills timelines.

Architecture and Design

The right stack is chosen (Kotlin or Java), scale is planned for, and an interface is designed following Google's Material Design 3 guidelines that your users will understand on the first session.

Agile Build

Development happens in two-week sprints, shipping testable builds so you see real progress constantly. Every sprint includes QA on real Android devices, not just emulators.

Launch and Iteration

Google Play Store submission is handled, performance is monitored post-launch, and the app keeps improving based on real user data. Launch is where the product journey begins.

Pricing

Investment Overview

Scope

Every feature multiplies build time. An MVP with 5 core features costs far less than a full platform with 20. Start lean and validate first.

Complexity

Real-time features, AI integration, offline-first architecture, background sync, and device-specific hardware access all add significant engineering hours.

Device Coverage

Supporting the latest Pixel phones is straightforward. Supporting Samsung, Xiaomi, Oppo, and older Android versions adds testing and adaptation time.
