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

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