Building an Android app starts with a well-defined objective and awareness of device variety. Clarifying the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release targeted and minimizes rework as the app expands.

Once the foundation is set, focus moves to a consistent UI, strong performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
