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

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