Starting Android app development requires a well-defined goal and awareness of device variety. Clarifying the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to consistent UI, speed, and compatibility across OS versions and different screen sizes. Robust state management, careful networking, and trustworthy analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
