Starting with a well-defined product goal and awareness of device variety sets the direction for Android app development. Outlining the MVP, selecting an architecture, and mapping core user journeys early help keep the initial release focused and minimize rework as the app grows.
Once the foundation is established, the focus shifts to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state handling, careful networking, and dependable analytics/crash reporting make the app easier to support and iterate on after Google Play release.
