Starting Android app development requires a well-defined product objective and awareness of device variety. Clarifying the MVP, choosing an architecture, and outlining key user journeys early on keeps the initial release tight and minimizes rework as the app expands.

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