Android app development starts with a well-defined product goal and an awareness of device fragmentation. Setting the MVP, choosing an architecture, and outlining key user journeys early ensures the initial release stays 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, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
