Building Android apps starts with a well-defined goal and awareness of device fragmentation. By outlining the MVP, choosing an architecture, and mapping essential user journeys upfront, the initial release stays focused and minimizes rework as the app evolves.

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