Creating Android applications starts with a well-defined goal and awareness of device variety. Outlining the MVP, choosing an architecture, and mapping key user journeys early keeps the initial release focused and lowers rework as the app expands.

Once the foundation is set, focus moves to UI consistency, performance, and compatibility across OS versions and screen dimensions. Robust state management, careful networking, and reliable analytics/crash reporting make the app easier to support and iterate on after Google Play release.
