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

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