Starting Android app development requires a well-defined product objective and awareness of varied devices. Outlining the MVP, choosing an architecture, and mapping 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 coherence, performance, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and trustworthy analytics/crash reporting simplify ongoing support and iteration after the Google Play launch.
