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

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