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

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
