Starting Android app development involves a well-defined product objective and awareness of device variability. Establishing the MVP, choosing an architecture, and mapping essential user journeys 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 OS versions and display dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
