Building Android apps starts with a well-defined goal and awareness of device variety. Clarifying the MVP, choosing an architecture, and mapping core user flows 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 streamline support and iteration after the Google Play launch.
