Starting Android app development involves a well-defined goal for the product and awareness of device diversity. Clarifying the MVP, choosing an overall architecture, and mapping key user flows early help keep the initial release focused and minimize rework as the app evolves.

Once the foundation is set, focus shifts to consistent UI, performance, and compatibility across different OS versions and screen sizes. Robust state handling, careful networking, and dependable analytics and crash reporting simplify support and iteration after the app reaches Google Play.
