Starting Android app development requires a well-defined product objective and awareness of device variation. Clarifying the MVP, choosing an architecture, and mapping essential user flows upfront keeps the initial release focused and minimizes rework as the app expands.

With the foundation established, focus moves to UI uniformity, 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 the Google Play launch.
