Starting Android app development requires a well-defined product goal and awareness of device variation. Outlining the MVP, choosing an architecture, and outlining key user journeys early helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI consistency, performance, and cross-version and screen-size compatibility. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
