Android App Development
Android’s hard part isn’t the emulator — it’s the thousand devices, screen sizes and Android versions your users actually have, and a Google Play review that is stricter than it used to be. As a freelance Android app developer I build and test for the real ones, and handle the backend too.
When to hire an Android app developer
- You need an Android app and want one person for the app, the backend and the store.
- Your users are on Android first — many markets are — and iOS can follow.
- An app works on one phone and misbehaves on others.
- You need Android-specific work done properly: Google sign-in, push notifications, Play Billing, background work, permissions.
- A Play Store submission is stuck in review or policy questions.
How I build an Android app
- 01
Agree what version one actually is
The smallest app that is genuinely useful, on real devices, before the rest gets built.
- 02
Flutter, with Android-native behaviour where it matters
One codebase that can ship to iOS later, with Android-specific work where it matters: Google sign-in, push notifications (via Firebase), in-app purchases (Google Play Billing), background tasks, permission prompts, and layouts that hold up across screen sizes.
- 03
Tested where users are
Real devices across OS versions and manufacturers, not one emulator — that is where Android apps actually fail.
- 04
Play Console, review, release
App signing, the Google Play Console listing, the data-safety form, releasing to a small percentage of users first, and the policy questions Google asks. Included.
How long it takes
A focused first version is usually three to five weeks, depending on the requirements — the backend behind it, payments, offline use. Play review is usually faster than Apple’s but can ask policy questions. Tell me what it needs to do and I’ll give you a real number.
Questions about this
Can you build something from scratch?
Yes — mobile, web and AI-powered products. It's a different engagement from a rescue: we start with what the thing actually needs to do, and I'll usually push to get a small version in front of real users before building the rest. If your idea is better served by something simpler than what you're picturing, I'll say so.
Flutter or native — which is better for my iOS or Android app?
For almost every startup app, Flutter: one codebase that runs on both iPhone and Android, with native code added only where a platform genuinely needs it — payments, notifications, sign-in. Fully native (Swift for iOS, Kotlin for Android) makes sense when the app is the platform: heavy graphics, AR, or deep OS integration. If your app is screens over an API — most are — Flutter gets you to both stores faster and cheaper, and it doesn’t feel like a compromise.
Do I need an Apple Developer or Google Play account before you start?
Not before we start, but you will need them before release, and they should be in your name, not mine — that is what keeps you in control of your app. Apple’s costs $99 a year and Google’s a one-off $25. I’ll tell you exactly when to set each up and walk you through it.
Can you help with deployment?
Yes, and it’s one of the most common reasons people get in touch. "It works locally" is almost always an environment, configuration or build problem rather than a code problem, and those are findable.
Your AI-built app doesn’t need another prompt.
It might need an engineer.
If you’ve spent hours asking AI to fix the same problem and you’re going in circles, stop fighting the code. Send me what you’ve got — I’ll figure out what’s wrong and tell you what I’d do next.
No cleanup. No judgment. The messy version is usually the useful version.
