Android Development Services

What is Android development at TPC?

Android development at TPC means writing Kotlin against the modern Jetpack stack and Compose-first UI. We target a wide device matrix — phones, tablets, foldables, and Wear OS where relevant — and we treat configuration changes, background restrictions, and battery optimization as first-class concerns rather than afterthought edge cases. We do not ship Java codebases held together with RxJava; we ship Kotlin with coroutines and structured concurrency.

Like our iOS practice, the Play Store listing, Data Safety form, signing keys, and release tracks are part of the engineering scope. We do not throw a build over the wall and ask someone else to figure out distribution.

When you need this

Hire us for Android work when you need a real native experience — fast scroll, real background sync, sensors, NFC, foreground services, or anything that depends on the platform behaving like Android instead of like a browser. We are a strong fit for fintech, health, logistics, and consumer products where Android is the primary or only mobile surface for the target user.

If you need a cross-platform Flutter or React Native app, or if you want us to keep a five-year-old AsyncTask-based codebase alive without a path forward, we are not the right team.

Our approach

We get a release-signed APK into Play Console's internal testing track in the first week. From there we iterate weekly — Compose screens, ViewModel logic, data sources, sync — with feature flags for anything that needs to be shipped dark. We write instrumentation tests for the surfaces that actually change behavior under load and unit tests against the parts of the app where logic lives.

We minimize third-party SDKs. Every dependency added is a future migration risk; we audit transitive dependencies and prefer first-party Jetpack libraries where they exist.

Tech stack we use

Language & UI: Kotlin, Jetpack Compose with Material 3, Compose Navigation, and Compose for Wear OS.
Concurrency: Kotlin coroutines, Flow, structured concurrency, WorkManager for deferrable background work.
Persistence: Room for SQLite, DataStore for preferences, encrypted storage via Jetpack Security.
Networking: Ktor or Retrofit with kotlinx.serialization, OkHttp interceptors for auth and telemetry.
Build & distribution: Gradle with version catalogs, R8/ProGuard, Android App Bundles, Play Console internal / closed / open / production tracks, Firebase App Distribution for non-Play beta channels.

Typical engagement

A first-version Android engagement runs eight to sixteen weeks. Week one produces an internal-track build with the navigation spine and one real screen. Subsequent weeks add real features, harden the data model, and prepare the Play Store listing including the Data Safety questionnaire and content rating. We submit to production ourselves and stay through the first point-release.

Examples of work

Recent Android work includes consumer apps with offline-first sync over Room and a custom conflict resolver, an internal field-tools app with foreground services for GPS tracking, and a Compose-based companion app that pairs with a BLE peripheral. We can share specifics under NDA on request.

What we don't do: Flutter, React Native, Xamarin, Cordova, or legacy Java/AsyncTask maintenance without a migration plan to Kotlin and Compose.
