Android app development starts with a well-defined product goal and an understanding of device variety. Defining the MVP, choosing an architecture, and mapping out key user flows early keeps the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus shifts to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust data handling, careful networking, and dependable analytics/crash reporting simplify ongoing support and iteration after the Google Play launch.
