Android app development starts with a well-defined product goal and recognition of device diversity. Defining the MVP, selecting an architecture, and outlining core user flows early helps keep the initial release focused and minimizes rework as the app grows.

Once the foundation is established, focus shifts to UI consistency, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting make the app easier to support and iterate after the Google Play launch.
