Starting Android app development with a well-defined product objective and awareness of device variety sets the foundation. 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 fundamentals exist, focus moves to a coherent UI, efficiency, and cross-version OS and screen-size compatibility. Robust state management, prudent networking, and dependable analytics and crash reporting simplify maintenance and iteration following the Google Play launch.
