Starting Android app development involves a well-defined product objective and awareness of device variety. Clarifying the MVP, choosing an architecture, and outlining key user journeys early on keeps the initial release focused and minimizes rework as the app expands.

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