Beginning Android app development hinges on a well-defined goal and awareness of device variability. Establishing the MVP, choosing an appropriate architecture, and mapping out key user journeys early on keep the initial release focused and minimize rework as the app evolves.

Once the foundation is established, focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting ease ongoing support and iteration after launching on Google Play.
