Building Android apps starts with a well-defined product objective and awareness of device variety. Outlining the MVP, choosing 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 moves to UI coherence, performance, and compatibility across OS versions and screen dimensions. Robust state management, thoughtful networking, and trustworthy analytics/crash reporting simplify maintenance and iteration after releasing on Google Play.
