Starting Android app development with a well-defined goal and awareness of device variety sets the stage. Establishing the MVP, choosing an architecture, and outlining essential user journeys early keeps the initial release focused and minimizes rework as the app expands.

Once the foundation is established, focus turns to a cohesive UI, performance, and compatibility across OS versions and screen sizes. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
