Starting Android app development requires a well-defined product objective and awareness of device variety. Setting the MVP, choosing an architecture, and outlining key user journeys early helps maintain focus for the initial release and minimizes rework as the app expands.

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