Creating an Android app starts with a well-defined product objective and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping essential user journeys early helps keep the initial launch targeted and minimizes rework as the app evolves.

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