Redian builds native Android applications in Kotlin and Jetpack Compose for banks, insurers, retailers and enterprise field teams. Our benchmark is not "it runs" — it is a build that starts fast on a mid-tier device, holds state across process death, degrades gracefully on 2G, and passes Play Store review the first time. We treat Android as a first-class client, not a WebView wrapper on someone else's stack.
What we build
Consumer and corporate banking apps for retail customers, RMs and field collections agents — with biometric login, device binding, transaction signing, offline statement caching and integration into the bank's core, card management platform and dispute workflows. Where the regulator requires it (RBI in India, CBK in Kenya, SAMA in Saudi Arabia, CBN in Nigeria), we implement root/emulator detection, SSL pinning, screenshot suppression on sensitive screens and hardware-backed key attestation via the Android Keystore.
Policyholder and agent apps for insurers — quote, buy, endorse, upload claim documents, track motor and health claim status, e-KYC via DigiLocker or national eID, IRDAI/IRA-aligned disclosures. Field survey apps for motor and property claim assessors with photo capture, geo-stamping and offline sync back to the claims engine.
Merchant, distributor and sales-force apps for FMCG, agri-inputs and pharma — beat plans, van sales, order capture, returns, credit exposure checks, printer/scanner integration, and MDM-managed rollouts across dealer devices. Warehouse and logistics apps with Zebra/Honeywell scanner support, DataWedge integration and offline-first order picking. Internal enterprise apps that plug into Zoho, Odoo, Salesforce, MS Dynamics or SuiteCRM as the system of record — the same stacks our CRM and ERP practice implements on the backend.
The stack we standardise on
Kotlin is the only language we ship in for greenfield work. Jetpack Compose is the default UI toolkit; we still support View/XML surfaces where existing apps demand it, and we know how to migrate a screen at a time rather than force a rewrite.
Concurrency is coroutines and Flow — structured, cancellable, tested. We use StateFlow for UI state, SharedFlow for events, and Channel only where the semantics demand it. Dependency injection is Hilt. Persistence is Room with proper migrations, DataStore for preferences, and encrypted storage via Jetpack Security for anything sensitive. Networking is Retrofit with OkHttp interceptors for auth, logging and pinning; large payloads and streaming use Ktor client where it fits better.
Navigation is the Compose Navigation component with type-safe routes. Background work is WorkManager — not ad-hoc services, not deprecated JobScheduler wrappers. Media, camera and ML surfaces go through CameraX and ML Kit; on-device inference uses TensorFlow Lite or MediaPipe when the use case warrants a model on the handset rather than a round trip.
Architecture is MVI or MVVM with a clean separation of data, domain and presentation layers. We write unit tests with JUnit and MockK, UI tests with Compose testing APIs and Espresso where needed, and screenshot tests with Paparazzi or Roborazzi to catch visual regressions before they reach QA.
Performance, accessibility and store readiness
Performance is treated as a first-class requirement, not a post-launch fix. We profile with Android Studio's system trace and Macrobenchmark, watch startup time and jank on Firebase Performance Monitoring, and ship Baseline Profiles and Startup Profiles so cold start on mid-range Android Go and Android One devices stays acceptable. R8 is configured and its output audited — we do not ship shrinker warnings.
Accessibility is not optional. Compose semantics, content descriptions, minimum touch targets, dynamic type, TalkBack traversal order and colour contrast are part of the definition of done. For BFSI clients this is also a compliance surface — the FCA, the CBK and the RBI all now expect accessible digital channels.
Release engineering is handled end to end. Gradle version catalogs, modularised builds, signed release variants, Play App Signing, phased rollouts, Play Console listing, data safety form, closed and open testing tracks, and Play Integrity API for anti-tampering. Crash and ANR triage runs on Firebase Crashlytics or Sentry with symbol upload wired into CI. Analytics goes through whatever the client has standardised on — Firebase, Amplitude, Mixpanel or a first-party pipeline.
Backend and integration
Most apps we build are the thin end of a larger stack. Backends are typically Spring Boot, Node or .NET talking to a core system — Finacle, Flexcube, Temenos, T24, BankSmart, PremiaX, or an in-house policy admin platform — via REST, GraphQL or ISO 8583/20022 for payments. We handle the client-side of OAuth 2.0 / OIDC, mTLS, JWT rotation, biometric-bound session tokens and offline conflict resolution.
Where the client needs an iOS counterpart, the same engineering group ships both platforms with a shared design system and API contract; where a hybrid approach genuinely fits, we are honest about that too. Our default, though, remains native — the performance floor, accessibility surface and platform integration are worth it for anything customers or field staff use every day.
Working with Redian
Engagements run either as a fixed-scope delivery — discovery, design, build, hardening, Play Store release, handover — or as an embedded pod inside your existing mobile team through IT staff augmentation. Either way you get Kotlin engineers, a mobile architect, QA with device-lab coverage and a release manager who has shipped through Play Console before.
Recent Android work spans retail banking, microfinance, health insurance, distributor sales and field logistics across India, Kenya, UAE and the UK. See case studies for representative deliveries, or get in touch to scope a build.
