Starting Android app development with a well-defined goal and awareness of device variety sets the stage. Defining the MVP, choosing an architecture, and mapping essential user flows early helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is established, focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state handling, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after release to Google Play.
