Starting Android app development requires a well-defined product objective and awareness of device variability. Outlining the MVP, choosing an architecture, and mapping essential user flows at the outset keeps the initial release targeted and minimizes rework as the app scales.

Once the foundation is established, focus moves to UI uniformity, performance, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after launch on Google Play.
