Building Android apps starts with a well-defined product objective and awareness of device variety. By outlining the MVP, choosing an architecture, and mapping essential user flows early, the initial release stays focused and minimizes rework as the app expands.

Once the foundation is established, 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 help sustain and iterate the app after its Google Play launch.
