Starting Android app development involves a well-defined product objective 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 evolves.

With the foundation established, focus then moves to UI uniformity, performance, and compatibility across different OS versions and display sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify ongoing support and iteration following the Google Play launch.
