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

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