Starting Android app development requires a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus turns to UI uniformity, performance, and compatibility across different OS versions and screen resolutions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
