Starting Android app development involves a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys at the outset keeps the initial release focused and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI uniformity, performance, and compatibility across OS versions and display sizes. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
