Starting with a well-defined product objective and awareness of device variety is key. By outlining the MVP, choosing an architecture, and mapping essential user flows early, the initial release stays focused and minimizes rework as the app expands.

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