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

Once the foundation is set, focus moves to UI coherence, performance, and compatibility across different OS versions and screen sizes. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration post-Google Play launch.
