Starting Android app development hinges on a well-defined product objective and awareness of varying devices. Establishing the MVP, choosing an architecture, and outlining key user journeys early keeps the initial release targeted and minimizes rework as the app expands.

Once the foundation is set, focus moves to ensuring a consistent UI, optimal performance, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
