Starting Android app development requires a well-defined product objective and awareness of device variability. Outlining the MVP, choosing an architecture, and mapping essential user journeys early keeps the initial release targeted and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI coherence, performance, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after publishing on Google Play.
