Building Android apps starts with a well-defined product objective and awareness of device variations. Outlining 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 established, focus moves to UI consistency, speed, and compatibility across different OS versions and display sizes. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
