Android app development begins with a well-defined product objective and an understanding of device variety. Defining the MVP, choosing an architecture, and outlining key user journeys early helps keep the initial release focused and minimizes rework as the app grows.

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