Building Android apps starts by establishing a well-defined product objective and recognizing the range of devices users may employ. Pinpointing the MVP, choosing an architectural approach, and outlining key user journeys early on helps keep the initial release tight and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI coherence, throughput, and compatibility across different OS versions and display sizes. Robust state management, prudent networking, and trustworthy analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
