Starting Android app development requires a well-defined product objective and awareness of device variability. Clarifying the MVP, choosing an architectural approach, and outlining key user journeys early on keeps the initial release focused and minimizes rework as the app scales.

With the foundation set, focus moves to UI uniformity, speed, and compatibility across OS versions and screen dimensions. Robust state management, meticulous networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
