Starting Android app development with a well-defined objective and awareness of device variety sets the foundation. Outlining the MVP, choosing an architecture, and mapping essential user journeys early ensures the initial release stays targeted and minimizes rework as the app expands.

Once the foundation is established, focus moves to a consistent user interface, performance, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics and crash reporting simplify maintenance and iteration after the Google Play launch.
