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

Once the core is established, focus moves to UI uniformity, performance, and compatibility across OS versions and display dimensions. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
