An Android app development service covers more than writing code for one platform — it includes planning the app's logic, designing its interface, building it, testing on real devices, and publishing it to Google Play. Here's how Jar Agency runs that process, what determines pricing, how long a typical project takes, and the mistakes worth avoiding before committing to a development plan.
What an Android app development service includes
The service starts before any code is written: mapping out what the app needs to do, for whom, and what it connects to. That structure guides everything that follows — design, development, and testing.
Development itself covers the interface, the underlying logic, and any integrations the app needs — payments, maps, push notifications, or a connection to an existing system.
This planning stage also defines what 'done' looks like for the project — a clear list of screens and behaviors that both the client and the development team agree on before design work begins.
From idea to Google Play publication
Publishing to Google Play is the final step of the development service, not a separate purchase. It includes preparing the store listing and making sure the app meets the platform's requirements before it goes live.
We treat this as part of the project scope from the start, so there is no gap between a finished app and one that is actually available to install.
We also make sure the store listing itself — screenshots, description, category — is prepared thoughtfully, since it's often the first thing a potential user sees before deciding whether to install the app at all.
Cross-platform or native for Android
A cross-platform approach shares one codebase across Android and iOS, which is usually faster and less expensive than building each platform separately — a good fit for most business apps: catalogs, orders, client accounts.
A native approach makes more sense when the app depends heavily on camera access, real-time location, or complex animation — cases where a shared codebase tends to lose performance.
We decide the approach with the client after the brief, based on what the app actually needs to do, rather than defaulting to one option for every project.
The decision is not permanent either — some projects start cross-platform and later add native components for a specific feature that needs better performance, without rebuilding the whole app.
Pricing factors
Pricing is quoted per project rather than as a flat rate, since 'an Android app' can mean a simple catalog or a full service with payments and a user account — a large difference in scope and cost.
The main factors are the number of screens, the integrations required, and how much backend logic the app needs. We provide a breakdown by section so the client sees where the budget goes.
We also account for ongoing costs beyond the initial build — hosting, maintenance as Android versions update, and the effort needed to keep third-party integrations working over time.
Timeline
A simple app with a narrow feature set can be built in a matter of weeks. A project with several integrations and custom logic takes longer, and the exact timeline is set after the brief and written into the agreement.
Development moves in stages, with working versions shown along the way rather than a single delivery at the very end.
Testing happens on a range of real Android devices rather than a single reference phone, since screen sizes and hardware performance vary widely across the devices people actually use.
Common mistakes when ordering Android development
Ordering a full-featured app before validating demand through a cheaper channel — a website or social media — is the most common mistake. Apps cost more to build and maintain than sites, and should solve a demand that is already confirmed.
Skipping the planning stage and moving straight to screen design is another. Without a clear structure, the app tends to be reworked later, which costs more than proper planning would have upfront.
Testing also covers edge cases like poor network connectivity, which is common on mobile in many regions — an app that only works well on fast, stable Wi-Fi will frustrate a large share of real users.
Our approach
We start with a brief covering the task, the audience, and the needed integrations, then move through design, development, testing on real devices, and publication to Google Play.
The whole process runs inside one team, and we remain available after launch — Android updates over time, and apps need occasional adjustments to keep working correctly.
We also document the app's structure as it's built, so future changes — whether made by us or another team later on — don't require reverse-engineering decisions made early in the project.

Частые вопросы
How much does Android app development cost?+
Pricing is quoted per project after a brief, based on the number of screens, integrations, and backend logic required. There is no fixed price that applies to every Android app.
Should we choose cross-platform or native development?+
Cross-platform works well for most business apps — catalogs, orders, client accounts. Native development makes more sense for apps that depend heavily on camera access or real-time location.
Do you publish the app to Google Play?+
Yes, publishing is part of the development service, including preparing the store listing and meeting platform requirements before the app goes live.
How long does Android app development take?+
A simple app can take a few weeks. A project with multiple integrations and custom logic takes longer — the exact timeline is set after the brief.
What is the most common mistake when ordering an Android app?+
Building a full-featured app before demand is validated through a cheaper channel, like a website. Apps cost more to build and maintain, so it helps to confirm the demand first.
