Building Android applications starts with a definite product objective and awareness of device variation. 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 uniformity, speed, and cross-version and multi-screen compatibility. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration following a Google Play launch.
