Android app development starts with a well-defined product objective and awareness of device variety. Clarifying the MVP, choosing an architecture, and mapping key user journeys early helps keep the initial release focused and minimizes rework as the app scales.

Once the foundation is set, focus moves to UI uniformity, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
