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 on keeps the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to consistent UI, performance, and compatibility across different OS versions and display dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
