Starting Android app development involves a well-defined product objective and awareness of device variety. Establishing the MVP, choosing an architecture, and outlining key user flows early keeps the initial release focused and minimizes rework as the app expands.

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