Building Android apps starts with a definite product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys upfront helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI uniformity, performance, and compatibility across OS versions and screen dimensions. Robust state management, meticulous networking, and dependable analytics/crash reporting streamline support and iteration after launch on Google Play.
