Starting Android app development requires a well-defined product goal and awareness of device variation. Pinpointing the MVP, choosing an architecture, and outlining primary user flows early helps ensure the initial release stays focused and minimizes rework as the app expands.

Once the foundation is established, focus moves to UI consistency, performance, and compatibility across different OS versions and screen dimensions. Robust state management, prudent networking, and dependable analytics/crash reporting simplify sustaining and iterating the app after it goes live on Google Play.
