Starting Android app development requires a well-defined product objective and awareness of a wide range of devices. Establishing the MVP, choosing an architecture, and outlining key user journeys early keeps the initial release focused and minimizes refactoring as the app expands.

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