Starting Android app development involves a definite product objective and awareness of device variations. Clarifying the MVP, choosing an architecture, and outlining essential user journeys early keeps the initial release focused and minimizes rework as the app expands.

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