Building Android apps begins with a well-defined goal and an awareness of device variety. Establishing the MVP, selecting an architecture, and outlining essential user journeys early on helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus shifts to a cohesive UI, performance, and compatibility across different OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify support and iteration after the Google Play release.
