Designing Android apps starts with a well-defined product goal and awareness of device variety. Defining the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release focused and minimizes rework as the app expands.
Once the foundation is set, focus moves to consistent UI, performance, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after releasing on Google Play.
