Starting Android app development requires a well-defined product goal and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial launch targeted and minimizes rework as the app expands.

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