Effective Android app development starts with a definite product goal and awareness of device variety. Defining the MVP, choosing an architecture, and mapping key user flows early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is in place, the focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting ease maintenance and iteration after the Google Play launch.
