Android App Development Services for Native Android Products
Unisam Technologies provides Android app development services for businesses and product teams that need native applications built specifically for the Android ecosystem.
We plan, design and develop Android applications using technologies such as Kotlin, Jetpack Compose, Android Jetpack and Android Studio, with support for backend connectivity, device capabilities, testing and Google Play release preparation.
Our Android development work can cover new products, existing applications, Kotlin development, legacy Android modernization and ongoing feature development.
Native Android Applications
Native Android Development Built Around Real Product Requirements
Android applications operate across different devices, screen sizes, hardware configurations and operating environments.
A production Android app therefore needs more than a set of mobile screens. It may need application logic, user accounts, APIs, local data handling, notifications, device functionality, responsive interfaces and reliable behavior across the devices included in the product scope.
Unisam Technologies develops Android applications around those actual requirements. This gives the project a defined Android scope before development begins.
Required Application Workflows
Define the required application workflows and user actions before development begins.
Supported Android Devices
Plan support for the Android devices included in the product scope.
Backend and API Dependencies
Review backend services and API dependencies required by the Android application.
Authentication Requirements
Define the authentication requirements needed for account access and application security.
Device Capabilities
Identify the device capabilities required for the Android application's functionality.
Application Data
Plan how application data will be handled within the Android product.
Third-Party Integrations
Identify the third-party integrations required by the Android application.
Google Play Release Requirements
Prepare the Google Play release requirements before Android application deployment.
Our Android App Development Services
Our Android application development services can cover an entire new product or a specific part of an existing Android application.
Custom Android App Development
We develop custom Android applications around defined product requirements, user workflows and business functionality.
Development can include application interfaces, user accounts, business logic, backend communication, local data, notifications, device capabilities and supported integrations.
Suitable for: businesses, startups and product teams building a dedicated Android application around their own requirements.
Native Android App Development
We build applications specifically for the Android platform using native Android technologies.
Native development can be appropriate when the product requires close integration with Android APIs, device capabilities, platform behavior or a dedicated Android codebase.
The technical structure is selected according to the application's functionality rather than applying the same architecture to every project.
Kotlin App Development
Kotlin can be used for application logic, networking, data handling, asynchronous operations and other parts of a native Android codebase.
We can use Kotlin for new Android applications as well as approved development or modernization work within existing Android projects.
Jetpack Compose Development
Jetpack Compose can be used to create native Android interfaces with reusable UI components and state-driven application screens.
We can use Compose for new Android interfaces or introduce it into suitable areas of an existing project where modernization is required.
The implementation approach depends on:
- the current Android codebase;
- supported
devices;
- application architecture;
- existing XML layouts;
- required features;
-
long-term product requirements.
Android UI Implementation
We develop Android interfaces around approved user flows and supported screen configurations.
The implementation can include:
- navigation;
- reusable interface components;
-
application states;
- forms;
- data-driven screens;
- dialogs and sheets;
- adaptive
layouts;
- loading and error behavior.
The goal is to create an Android experience that remains usable across the device configurations included in the project's scope.
Android API & Backend Integration
Many Android products depend on backend systems rather than operating entirely on the device.
We can connect Android applications with supported:
- REST APIs;
- backend
applications;
- authentication services;
- databases through appropriate backend
services;
- payment services;
- cloud platforms;
- business systems;
- analytics
platforms;
- third-party APIs.
Before implementing an integration, we review the available API, authentication method, required data and actions the Android application needs to perform.
Google Play Release Support
We can prepare Android applications for release through Google Play as part of the agreed project scope.
Release preparation can include:
- production build configuration;
- application
signing setup;
- Android App Bundle preparation;
- package configuration;
-
versioning;
- release testing;
- required store information coordination;
- issue
resolution during submission preparation.
Publication remains subject to Google's current Google Play policies, technical requirements and review processes.
Android App Maintenance & Continued Development
Android applications can require continued work after their first release as application requirements, backend systems, Android APIs and dependencies change.
Ongoing development can include:
- bug fixes;
- feature additions;
- API
changes;
- dependency updates;
- Android compatibility work;
- interface
improvements;
- performance improvements;
- Google Play release updates.
The maintenance scope is defined according to the requirements of the individual application.

Android Apps Across Phones, Tablets & Foldable Devices
Android applications can operate across a wide range of screen sizes and device configurations.
Instead of assuming that every user has the same phone layout, we can define the Android experience according to the devices the product is expected to support.
Android Phones
Interfaces can be optimized around the navigation, screen space and workflows required for supported Android phones.
Android Tablets
Applications that include tablet support can use layouts appropriate for larger available screen areas rather than simply stretching a phone interface.
Foldable Devices
Where foldables are part of the intended device scope, layouts and application states can be reviewed for changing screen configurations and available display space.
Resizable Android Windows
Applications that need to operate in supported resizable or multi-window environments can be designed to respond appropriately to changes in available application space.
Android Device Features & Platform Integrations
Where required by the product, an Android application can work with supported platform and device functionality.

Developing or Modernizing an Existing Android App
Not every Android project needs to start with a new codebase. Existing applications may need additional functionality, platform updates, API changes, UI modernization or technical improvements. We review the relevant parts of the existing project before defining the appropriate development approach.
New Android Features
Add approved screens, workflows and functionality to an existing application.
Java to Kotlin Modernization
Existing Java-based Android code can be reviewed for selective or broader migration to Kotlin where it provides a practical technical benefit. A complete rewrite is not automatically required.
XML to Jetpack Compose Modernization
Existing Android applications using traditional XML layouts can be reviewed to determine whether selected interfaces or new functionality should use Jetpack Compose. Modernization can be incremental where appropriate.
API & Backend Updates
Update the Android application when backend APIs, authentication flows or application data requirements change.
Dependency & Android Compatibility Updates
Review dependencies and application areas that need changes to remain compatible with the supported Android environment.
Interface & Navigation Improvements
Modernize selected Android screens and user flows without automatically rebuilding the entire application.
Our Android App Development Process
Each Android project is structured around its approved requirements rather than a fixed package.
Android Product Requirements
We review the product goal, target users, supported Android devices, workflows, integrations and existing systems.
Application Scope & User Flows
We define the primary application journeys, screens, states, actions and functional requirements.
Android Technical Planning
We determine the Android architecture, required platform capabilities, APIs, backend dependencies and development technologies.
