Android app development starts with a well-defined goal and an awareness of device variation. Defining the MVP, choosing an architecture, and mapping key user flows upfront helps keep the initial release focused and minimizes rework as the app evolves.

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