Starting Android app creation with a well-defined goal and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early keeps the initial release focused and minimizes rework as the app expands.

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