Starting Android app development with a well-defined goal and awareness of device variety. Clarifying the MVP, choosing an architecture, and mapping key user journeys early helps keep the initial release focused and minimizes rework as the product expands.

Once the foundation is set, focus moves to UI consistency, performance, and cross-version/ screen-size compatibility. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
