Starting Android app development involves a well-defined product objective and awareness of varying devices. Outlining the minimum viable product, choosing an architecture, and mapping essential user journeys early keeps the initial release focused and lowers future rework as the app expands.

Once the foundation exists, focus shifts to consistent UI, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after releasing on Google Play.
