Android app development starts with a well-defined goal and awareness of device variety. Clarifying the MVP, choosing an architecture, and outlining key user journeys early helps keep the initial release targeted and minimizes rework as the app evolves.

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