Building an Android app starts with a well-defined product objective and awareness of device variations. Establishing the MVP, choosing an architecture, and outlining key user journeys early keeps the initial release focused and minimizes rework as the app expands.

With the foundation set, focus moves to a consistent UI, performance, and compatibility across different OS versions and screen sizes. Robust state management, thoughtful networking, and dependable analytics and crash reporting simplify maintenance and iteration after publishing on Google Play.
