A service for selling discount coupons for the Egyptian market. The killer feature — coupon buyers automatically become lottery participants. On this project, we had to work with Firebase for the first time to build the backend. With a tight deadline, we had to study the technology and implement features at the same time. Even then, the developers managed to complete the task ahead of the deadline.

Prepare and submit
an estimate

We prepare a detailed estimate and presentation, which includes cost, timeline, team, and project roadmap.

After that, all that's left is to sign the contract,and we'll get started on your project! Now, let's talk about what happens after the estimate.

Android app development process

The process runs through six stages: discovery, design, development, device-matrix QA, Google Play submission, and post-launch support. Device-matrix QA and Google Play submission ownership are the stages that have no direct iOS equivalent at this scale — covered in detail below.

Systems analysis

Results: Project roadmap and BPMN-diagrams

Average time frame: 2–3 weeks

We gather analytics and dive deeper into your project’s specifics. During this phase, we design the architecture of the Android app and create BPMN-diagrams that outline how the app will function. The thorough planning helps us anticipate potential challenges and adapt to changes.

UI/UX design

Results: UI kit, finished screen designs

Average time frame: 1-1.5 month

We start by mapping out the internal logic of the Android app in a detailed mind map. This serves as a foundation that we then transform into black-and-white wireframes.

Once you approve the app’s logic, we focus on designing 1-2 key screens from the primary user scenario to establish the app’s core style. After finalizing the style, we refine every detail, complete the app’s design, and create a UI kit to accelerate the development process.

Development

Results: Finished Android app that’s ready for release

Average time frame: 2–5 months

We break the app development process into 2-week sprints. This gives clients regular updates and more control over the progress of the project. The approach allows for quick adjustments and incorporation of changes.

Test releases are shared via TestFlight, so clients get to experience the app on real devices and evaluate its functionality first-hand.

QA testing

Results: Bug-free app

Average time frame: In parallel with the development

During development, we regularly check the app for bugs to reduce the chance of them making it into the release. To ensure that, we test each scenario using a combination of manual and automated methods.

Release

Results: An app that’s ready to be downloaded by users

We understand the process of publishing to the Play Store and make sure that every release is as smooth as possible. Our Android app development services don’t end there. We can also provide ongoing support — add new features and fix bugs as they appear.

Testing Across Android's Device Fragmentation

Android's device fragmentation is real and larger than iOS's by a wide margin: dozens of OEMs (Samsung, Xiaomi, OnePlus, Google, and smaller regional brands) each customize the OS layer, and production traffic on most Android apps still spans OS versions from Android 8 through Android 15. An app that renders correctly on a stock Pixel emulator can still break on a Samsung device with One UI's notification handling, or on a budget phone with a non-standard screen aspect ratio.

"We test on multiple devices" doesn’t say much without a device list attached. QA on an Android project at Purrweb runs against a mix of physical devices spanning at least two major OEM skins and the OS versions the client’s analytics show real users are on, not just the latest emulator image. Screen-size and aspect-ratio testing covers standard phones, larger-screen devices, and increasingly foldables.

The honest tradeoff for a founder: skipping device-matrix QA to save a sprint is the single most common way an Android launch collects one-star reviews about crashes the team never saw in their own testing.

Google Play Submission — Timelines and Ownership

Play Console setup, signing-key management, and Google's review correspondence usually land on the client's plate after handover. Purrweb runs submission as a deliverable: our team creates the Play Console listing, manages app signing and release tracks, and handles every round of review feedback until the app is live.

Google Play's automated review typically completes faster than Apple's manual App Store review — often within hours rather than days — though apps requesting sensitive permissions (background location, SMS, call logs) or falling into restricted categories (finance, health) can trigger a manual policy review that adds days. Common rejection reasons include incomplete data-safety declarations, permission requests that don't match the app's stated purpose, and target-API-level requirements Google updates annually.

A founder who's never filled out a Play Console data-safety form before can lose real time figuring out which permission maps to which disclosure category. Submission ownership means a policy flag is our problem to fix the same day it's raised.

Designing for Material Design and Android UI Guidelines

Material Design is Google's design system for Android, covering component behavior, elevation and shadow rules, motion patterns, and adaptive layouts across phone, tablet, and foldable form factors. An app that ignores it doesn't just look inconsistent — it fights the OS's own navigation gestures and system UI in ways users notice immediately, even if they can't name why the app feels off.

Purrweb's design team builds Android screens against Material Design 3 components and adaptive-layout guidelines from the first wireframe. That matters most for apps also shipping on iOS: a shared cross-platform codebase still needs two distinct visual languages underneath it, or the Android version reads as an afterthought to users who know the platform's conventions.

Android App Development Timeline — How Long Does It Take?

An Android MVP takes 8–16 weeks from kickoff to Google Play listing. A mid-complexity app runs 3–5 months, and enterprise builds take 6 months or longer. These timelines assume discovery is done before development sprints start and treat device-matrix QA as a distinct phase. Projects that skip discovery and figure out scope mid-build routinely run over their original estimate — scope creep during development is the biggest timeline risk on any Android project, not Play Store review delays.

Google Play's automated review typically adds hours to a submission timeline. Against a 16-week build, that's a rounding error next to the real variable: scope creep during development and the size of the device-matrix QA pass.

Our Android Development Stack: React Native and Flutter

Purrweb builds Android apps with React Native and Flutter. The same codebase ships to Android and iOS, which cuts build time compared to running two native teams in parallel. React Native uses TypeScript over a native bridge (or the newer Fabric renderer) to call native UI components. Flutter compiles Dart to native ARM code and renders its own widget tree, which is why Flutter apps tend to look pixel-identical across Android OEMs. Android Studio remains the build environment for packaging, signing, and Play Console uploads regardless of framework.

Both frameworks cover most of what a typical Android app needs: camera, push notifications, in-app billing, biometric auth, maps. Where a project needs something the framework doesn't expose yet — a home-screen widget built on Jetpack Compose, a deep OEM-specific API, or a specialized sensor integration — Purrweb writes a small native Kotlin module and bridges it into the React Native or Flutter codebase.

We don't market ourselves as a native Android shop building everything in Kotlin from scratch. For most products — an MVP validating demand, a multi-role marketplace app, a fintech app with a standard KYC flow — a shared React Native or Flutter codebase reaches both Android and iOS users at once, at a fraction of running two native teams. Native Kotlin earns its cost when a project needs deep platform integration on day one.

Some clients come to us with an existing native Android codebase written in Java, the language most legacy Android apps still run on. We don't rebuild those from scratch by default — the discovery call scopes whether a bridge, a partial rewrite, or a full cross-platform migration makes sense for that specific codebase.

Custom Android app development cost

Android app development costs $25,000–$60,000 for an MVP, $60,000–$150,000 for a mid-complexity app with backend and third-party integrations, and $150,000+ for enterprise-grade builds with custom infrastructure. These ranges reflect actual Purrweb project scopes.

One thing that inflates Android budgets specifically: device-matrix QA. Testing a payment flow or a camera feature across a handful of representative OEMs and OS versions takes real QA hours that a single-device iOS test cycle doesn't need. That's engineering time most cost calculators on competitor sites don't itemize separately — it shows up as a line item in our discovery-stage estimate instead of a surprise change order mid-build.

Case Studies

KEM — P2P payment app for the Kuwait market. A fintech startup came to us needing an MVP to pitch to banking partners before securing a banking API integration. We designed the UX/UI and built a cross-platform React Native MVP with mock banking data: phone-number signup, linked card management, peer-to-peer money requests. After handover, KEM's in-house team took over engineering, wired in real banking APIs, rebranded, and carried the product toward launch. One React Native codebase covered both target platforms from the first sprint.

Settler — apartment renovation app for Dubai. A Dubai-based renovation service needed an app connecting homeowners with contractors, including live-stream video of work in progress. We built Settler as a React Native MVP — renovation stage tracking, expense tracking, contractor receipts — and shipped it live on Google Play alongside the App Store in 4 months.

Fitness App — online workout platform for personal trainers. A fitness-industry client needed a platform connecting trainers with clients for remote coaching: video workouts, in-app chat, training-program scheduling, and Stripe payments. We built it with React Native and a Node.js backend, targeting both Google Play and the App Store as the client moved toward release.

All three case studies above were built with React Native — that's the default stack Purrweb runs for Android projects, cross-platform from day one, with native Kotlin modules added only where the framework needs a bridge.

Android vs Cross-Platform vs iOS: Choosing the Right Approach

Native Android development is the right call when an app needs deep platform integration — custom home-screen widgets, background processing tied to Android’s power-management APIs, or a hardware SDK with no cross-platform binding — or when performance on a single platform matters more than reaching iOS on day one. React Native app development makes more sense when the priority is shipping to both Android and iOS from one codebase, especially for MVPs validating a business model before platform-specific investment is justified.

The honest tradeoff: native Kotlin gives immediate access to every new Android API the day Google ships it. React Native and other cross-platform app development approaches wait on a bridge library or write a native module to fill the gap — which Purrweb does when a cross-platform project needs one native feature rather than a full rewrite. Teams building for iOS app development alongside Android from day one usually start cross-platform and split into native codebases later, once one platform’s feature set outgrows what the shared codebase can support cleanly.

A rough rule that holds across the projects we've scoped: if the roadmap includes deep OEM-specific integration or heavy background processing within the first year, native saves a rewrite later. If the roadmap is “validate demand on both platforms within a quarter,” cross-platform is the faster, cheaper first step.
