Building Android apps starts with a well-defined goal and awareness of device variety. Clarifying the MVP, choosing an architecture, and mapping essential user paths early keeps the initial release focused and minimizes rework as the app scales.

Once the foundation is set, focus moves to UI uniformity, performance, and compatibility across different OS versions and screen dimensions. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
