Storage of sensitive keys and tokens in a secure hardware module, reliable protection of banking operations and personal data.

[ 04 ]

Deep integration with Google services

Work with Google Maps, Firebase Cloud Messaging (FCM), Google Sign-In, ML Kit for barcode recognition and extended background services (WorkManager).

[ Stages of Android App Development ]

What is included in turnkey Android app development

Comprehensive engineering process from forming technical requirements to publication in Play Store

[ STEP 01 ] Architecture

Technical design and preparation of API specification

We analyze requirements, create an architectural plan (Clean Architecture + MVVM/MVI), describe contracts for interactions with the backend.

[ STEP 02 ] Design

Material Design 3 (Material You) adaptive design

We create interfaces according to official Google guidelines with dynamic color palettes and adaptation for screens with different pixel densities (mdpi–xxxhdpi).

[ STEP 03 ] Development

Development in Kotlin and Jetpack Compose

We are writing reliable code on a modern declarative UI framework Jetpack Compose using Coroutines, Flow, Hilt (DI) and Ktor/Retrofit.

[ STEP 04 ] Integrations

Integration of Google Pay, Push and local Room bases

Connecting payment for 1 click via Google Pay, fast background data caching in Room database and interactive Push notifications via Firebase FCM.

[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

Kotlin is the official standard for Google's Android development. It guarantees the highest rendering speed for complex lists, complete absence of crashes through external bridges, direct access to hardware features, and stable operation of background processes.

We use the Jetpack Compose framework with flexible containers, test the UI on different screen sizes (from budget models to flagship devices) and conduct automated testing on virtual and real devices.

Google Play app review may take up to 7 days, or longer in exceptional cases. Personal accounts created after 13 November 2023 require a closed test with at least 12 participants opted in continuously for 14 days before publication. We help organise testing and prepare the application for production access.

Yes, we necessarily design an Offline-First architecture based on a local Room database. The user can view saved data, catalog or drafts, and when the network appears, the app automatically synchronizes changes with the server.

Yes, you get full access to the Git repository with all commit history, signing key stores (Keystore) and technical documentation.
