Starting Android app development involves a well-defined product objective and awareness of device variety. By outlining the MVP, choosing an architectural approach, and mapping key user journeys upfront, the initial release stays targeted and minimizes rework as the app expands.

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