Android App Development Services

Design for the devices your users have

Android phones and tablets vary in screen size and OS version. We agree a supported device range and test plan, including navigation, keyboard behavior and larger-screen layouts.

Features with operational rules

Membership, notifications, QR scanning and staff workflows can be scoped around your service. We define permission handling, account deletion, data synchronization and failure states alongside the happy path.

Google Play and distribution

We help prepare the agreed release assets and technical checks. Your developer account, required testing, store policies and privacy declarations must be confirmed. Store review and approval timing remain outside ERA's control.

Can you connect an existing system?

We first review its API documentation and your access rights. Authentication, data mapping, rate limits and recurring provider fees are included in the scope discussion before a fixed quote.

Scope, cost and delivery

We confirm users, screens, integrations and content before issuing a quote valid for 14 days. Delivery dates follow confirmation of requirements and materials. Third-party hosting, store accounts and API fees are separate. Japan-market JPY starting prices are reference figures; overseas pricing and the contractual currency are agreed individually.

Project examples and working together

Client work is not currently published. We can discuss the proposed deliverables, review stages and technical approach for your project without disclosing another client's private work.

What should I include in my request?

Your users, must-have functions, current systems, budget and intended country of use help us assess the scope. Specifications do not need to be complete to start a conversation.
