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 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 different OS versions and screen sizes. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
