Starting Android app development involves a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release targeted and minimizes future 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, careful networking practices, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
