Starting Android app development requires a well-defined product goal and awareness of device variety. Outlining the MVP, choosing an architectural approach, and mapping essential user journeys early keeps the initial release focused and minimizes rework as the app expands.

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