Android app development begins with a well-defined product objective and an awareness of device variety. Outlining the MVP, picking an architecture, and mapping essential user flows early helps keep the first release targeted and reduces the need for rework as the app expands.

Once the foundation is in place, emphasis 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.
