Starting with a well-defined product goal and awareness of device variety is key to Android app development. By outlining the MVP, choosing an architecture, and mapping essential user flows upfront, the initial release stays focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to UI coherence, performance, and compatibility across different OS versions and screen dimensions. Robust state handling, thoughtful networking, and trustworthy analytics/crash reporting simplify maintenance and iteration after launching on Google Play.
