    Share your project requirements, preferred skills, engagement model, and expected timeline with us. Based on your needs, we shortlist Android developers with relevant experience in Kotlin, Java, Jetpack Compose, Firebase, secure APIs, testing, and Google Play deployment. You can review profiles, interview candidates, and select the developers who best fit your product roadmap.

    Capital Numbers gives you access to vetted, in-house Android developers who can work as an extension of your team. Our developers support new app development, Android app modernization, API integrations, AI-enabled features, performance optimization, testing, Google Play deployment, and post-launch support. You also get flexible engagement options, direct communication, delivery visibility, and lower hiring overhead compared to building a local team from scratch.

    Dedicated Android developers are better suited for businesses that need consistent delivery, long-term product support, code ownership, and predictable collaboration. Freelancers may work for short, isolated tasks, but they often lack the structured support needed for complex apps, roadmap changes, QA, security, and post-launch maintenance. With Capital Numbers, you get dedicated developers backed by project coordination, QA, DevOps, and delivery support when required.

    Our Android developers can build mobile apps for eCommerce, healthcare, fintech, logistics, education, media, on-demand services, enterprise mobility, and customer engagement. They can also support wearable apps, tablet apps, AI-enabled Android features, secure API integrations, Firebase-backed applications, payment flows, location-based features, push notifications, analytics, and Google Play deployment.

    Yes. Our Android developers can modernize legacy Android apps by improving code quality, upgrading dependencies, migrating to Kotlin where needed, adopting Jetpack Compose, improving UI performance, fixing crash issues, optimizing APIs, strengthening security, and preparing the app for newer Android versions and Google Play requirements. We begin by reviewing the existing codebase, architecture, dependencies, performance issues, and release readiness.

    The timeline depends on the app’s scope, number of screens, design complexity, backend/API requirements, third-party integrations, testing needs, and Google Play release process. A simple Android app or MVP may take a few weeks, while a feature-rich app with user roles, payments, dashboards, AI features, native integrations, and QA cycles may take several months. After reviewing your requirements, we can share a realistic timeline and team structure.

    Yes. You can hire Android developers from Capital Numbers on a full-time, part-time, hourly, staff augmentation, managed team, or fixed-cost model. This gives you flexibility to add Android expertise for short-term tasks, ongoing product development, modernization projects, release support, or long-term app maintenance based on your workload and budget.

    We follow secure development practices across authentication, API communication, data storage, permissions, encryption, dependency management, and release workflows. Our Android developers can implement secure coding standards, role-based access, safe credential handling, vulnerability checks, and app hardening practices where required. We also provide NDA-backed development to help protect your source code, product idea, credentials, and business logic.

    Yes. Our Android developers and QA teams can support unit testing, UI testing, device compatibility testing, regression testing, performance testing, crash checks, and release validation. We can also help prepare builds for Google Play deployment, manage version updates, resolve submission issues, and support post-release improvements based on user feedback and app performance.

    If the selected Android developer is not the right fit, we can review the concern and provide a suitable replacement where required. You can also adjust the engagement based on agreed terms. Our goal is to reduce hiring risk and help you work with Android developers who match your technical needs, communication style, and project goals.

    Yes. Capital Numbers provides post-launch support to keep your Android app stable, secure, and aligned with changing business needs. Our developers can support bug fixes, Android version updates, dependency upgrades, performance tuning, crash resolution, API changes, UI improvements, Google Play updates, and new feature enhancements.

    When evaluating an Android development company, look for proven experience in Android app development, expertise in Kotlin and Jetpack Compose, strong security practices, transparent delivery processes, and a portfolio of scalable applications. It's also important to assess communication, post-launch support, and the ability to align with your business goals.
