Building Android apps starts with a definite product objective and awareness of variety in devices. Establishing the MVP, choosing an architecture, and outlining key user flows early keeps the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across OS versions and display sizes. Robust state handling, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
