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

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