Starting Android app development involves a well-defined goal and awareness of the variety of devices. By outlining the MVP, choosing an architecture, and mapping essential user journeys early, the initial release stays focused and minimizes rework as the app expands.

Once the foundation is ready, focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iterations after the Google Play release.
