Starting Android app development involves a defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early ensures the initial release stays focused and minimizes rework as the app expands.

Once the foundation exists, focus moves to a consistent UI, performance, and compatibility across different OS versions and screen dimensions. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
