Android app development starts with a well-defined product objective and an appreciation for the variety of devices. Pinpointing the MVP, choosing an architecture, and outlining key user journeys early helps maintain focus for the initial release and minimizes rework as the app scales.
Once the foundation is in place, the focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify support and iteration after the Google Play release.
