Effective Android app development starts with a well-defined product goal and awareness of device variation. Defining the MVP, selecting an architecture, and outlining key user flows early helps keep the initial release focused and reduces rework as the app scales.

Once the foundation is established, focus shifts to a consistent UI, performance optimization, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify support and iteration after the Google Play launch.
