Starting Android app development involves a well-defined product objective and awareness of varying devices. Outlining the MVP, choosing an architecture, and mapping key user journeys early keeps the initial release focused and minimizes rework as the app scales.

Once the foundation is set, focus moves to UI uniformity, performance, and ensuring compatibility across OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash tracking simplify maintenance and iteration after the Google Play launch.
