Starting Android app development requires a well-defined product objective and awareness of device variety. By outlining the MVP, choosing an architecture, and mapping essential user journeys early, you keep the initial release focused and minimize rework as the app expands.

With the foundation established, focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
