Android app development starts with a clearly defined product objective and an understanding of device diversity. Defining the MVP, selecting an architecture, and outlining core user flows early help keep the initial release focused and minimize rework as the app grows.

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