Starting Android app development requires a clear product goal and awareness of device variation. Defining the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release focused and minimizes rework as the app expands.

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