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

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust data handling, careful networking, and reliable analytics and crash reporting make the app easier to maintain and iterate after its launch on Google Play.
