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

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