Starting with a well-defined product objective and awareness of device variety is essential in Android app development. By outlining the MVP, choosing an architecture, and mapping key user journeys early on, the initial release stays focused and minimizes rework as the app expands.

Once the foundation is set, focus shifts to a cohesive UI, efficiency, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics and crash reporting simplify maintenance and iteration after the Google Play launch.
