Starting Android app development requires a well-defined product objective and awareness of device variety. Establishing the MVP, choosing an architecture, and outlining key user journeys early keeps the initial release focused and minimizes rework as the app expands.

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