Starting Android app development involves a well-defined product goal and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user flows early keeps 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, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after publishing on the Google Play store.
