Android app development starts with a clearly defined product objective and an awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early helps keep the initial release focused and minimizes rework as the app expands.

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