Effective Android app development starts with a well-defined product objective and an appreciation for device diversity. By defining the MVP, choosing an architecture, and mapping out key user flows early, you keep the initial release focused and minimize rework as the app evolves.

Once the foundation is established, focus shifts to consistent UI, performance, and compatibility across OS versions and screen sizes. Reliable state management, careful networking, and dependable analytics/crash reporting help make the app easier to maintain and iterate on after it hits Google Play.
