Building an Android app starts with a well-defined goal and awareness of device variety. Setting the MVP, choosing an architecture, and outlining key user journeys early keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus shifts 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 the Google Play launch.
