Android app development starts with a clearly defined product objective and an awareness of device diversity. Articulating the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release targeted and minimizes rework as the app expands.

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