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

Once the foundation is set, focus moves to a coherent UI, performance, and compatibility across different OS versions and screen resolutions. Robust state management, thoughtful networking, and dependable analytics and crash reporting simplify maintenance and iteration after launching on the Play Store.
