Android app development starts with a well-defined product goal and insight into device diversity. Defining the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release focused and minimizes rework as the app expands.

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