Starting Android app development involves a well-defined product objective and awareness of the variety of devices. Outlining the MVP, choosing an architecture, and designing key user journeys early helps maintain a focused initial release and minimizes rework as the app expands.

Once the foundation is established, focus moves to a consistent user interface, 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 the Google Play release.
