Starting Android app development requires a well-defined goal for the product and awareness of varying devices. By outlining the MVP, choosing an architecture, and mapping essential user flows upfront, the initial release stays focused and minimizes rework as the app expands.

Once the foundation is established, focus moves to a consistent UI, 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 publishing on Google Play.
