Developing Android apps starts with a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early helps maintain a focused initial release and minimizes rework as the app evolves.

Once the foundation is set, focus moves to UI coherence, speed, and compatibility across different OS versions and display sizes. Robust state management, prudent networking, and trustworthy analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
