Starting with a well-defined product goal and awareness of device variety, Android application development should define the MVP, choose an architecture, and map core user flows early to keep the initial release focused and minimize rework as the app expands.

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across OS versions and different screens. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
