Starting an Android app project requires a well-defined goal and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping primary user flows early keeps the initial release focused and minimizes changes as the app scales.

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, prudent networking, and trustworthy analytics/crash reporting simplify maintenance and iteration after the Google Play release.
