Beginning Android app development with a well-defined product goal and an awareness of device variety sets the stage. Clarifying the MVP, choosing an architecture, and outlining primary user flows at the outset keeps the initial release targeted and lowers the need for rework as the app expands.

Once the foundation is established, focus shifts to UI consistency, performance, and compatibility across OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify ongoing support and iteration after the Google Play launch.
