Starting Android app development requires a definite product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early helps keep the initial release targeted and minimizes rework as the app expands.

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