Creating an Android app starts with a well-defined goal and awareness of device variety. Pinpointing the MVP, choosing an architecture, and outlining key user flows early keep the initial release focused and minimize rework as the app expands.

Once the foundation is set, focus moves to UI uniformity, performance, and compatibility across OS versions and displays. Robust state management, prudent networking, and dependable analytics/crash reporting help maintain and iterate the app after launch on Google Play.
