Starting Android app development with a definite product goal and awareness of device variety sets the stage. Defining the MVP, choosing an architecture, and outlining core user flows early keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, efforts pivot to UI consistency, performance, and ensuring compatibility across OS versions and different screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify support and iteration after publishing on Google Play.
