Android runs on more than 70% of smartphones globally, and in emerging markets that share climbs past 90%. If your audience is worldwide — or price-sensitive — Android is usually the first platform to build for. Here is what the process looks like in 2026.

How Android Apps Are Built Today

The modern native stack is Kotlin with Jetpack Compose, the declarative UI toolkit that replaced XML layouts for new projects. Java remains supported but is legacy for new work. Many teams instead choose Flutter or React Native to cover Android and iOS with one codebase — a decision covered later in this guide.

Native Kotlin vs Cross-Platform

  • Choose native Kotlin when you need deep hardware integration, top-tier performance, or Android-only distribution — for example enterprise field tools or device-heavy products.
  • Choose cross-platform when you need both stores on a startup budget. Modern Flutter apps are close to indistinguishable from native for typical business use cases.

What Android Development Costs

App complexityTypical global rangeTimeline
Simple (few screens, no backend)$5,000 – $20,0006–10 weeks
Medium (accounts, API, payments)$20,000 – $70,0003–5 months
Complex (real-time, marketplace)$70,000+6+ months

Outsourcing to experienced teams in Nepal, India or Eastern Europe typically cuts these figures by 40–60% without sacrificing seniority — the same engineering talent simply costs less in those markets.

Publishing on Google Play

  1. One-time $25 developer account fee.
  2. Store listing: title, description, screenshots, feature graphic — all searchable, so treat them as SEO.
  3. Automated review plus policy checks; new developer accounts face extra testing requirements before production release.
  4. Staged rollouts let you release to 5% of users first and halt if crashes spike.

Why Device Fragmentation Deserves a Real Testing Budget Line

The device fragmentation challenge mentioned below is worth quantifying, because it directly affects how much QA time an Android project genuinely needs compared to iOS. Where iOS testing can reasonably cover a handful of current iPhone models, Android's open hardware ecosystem means real users run the app across screen sizes ranging from small budget phones to large foldables, on hardware from dozens of manufacturers each with slightly different default settings, camera behavior and performance characteristics. A responsible Android QA process budgets for testing on a deliberately chosen representative device matrix — not every device, but a spread covering low-end, mid-range and high-end hardware across at least two or three Android versions — rather than assuming a single test device (often the developer's own phone) represents the real user base.

The Android-Specific Challenges

  • Device fragmentation: thousands of screen sizes and hardware combinations demand a defined test matrix.
  • OS version spread: unlike iOS, many users run Android versions several years old.
  • Play policy churn: target-SDK deadlines each year force at least annual maintenance releases.

Frequently Asked Questions

Should I build Android first or iOS first?

Follow your audience. Global consumer and emerging-market products usually start with Android; premium subscription products often start with iOS where spending per user is higher.

Is Kotlin hard to hire for?

No — Kotlin has been the standard for years and the global talent pool is deep, especially through outsourcing partners.

What is a reasonable device test matrix for a typical business app?

A handful of devices spanning budget, mid-range and flagship tiers, across the two or three most common Android versions in your target market, generally catches the large majority of real-world layout and performance issues without needing exhaustive coverage of every possible device.
