Starting Android app development requires a clear product goal plus awareness of device variety. Defining the MVP, choosing an architecture, and outlining key user flows early on keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, the focus shifts to consistent UI, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics and crash reporting help support and iterate the app more easily after it's released on Google Play.
