Android app development starts with a clearly defined product goal and an understanding of device diversity. Defining the MVP, selecting an architectural approach, and outlining key user flows early helps keep the initial release focused and minimizes rework as the app grows.

Once the foundation is in place, the focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and reliable analytics and crash reporting make the app easier to maintain and iterate after the Google Play launch.
