Starting Android app development requires a well-defined product objective and awareness of various devices. By outlining the MVP, choosing an architecture, and mapping key user journeys upfront, the initial release stays focused and minimizes rework as the app expands.

Once the foundation is set, focus moves to a consistent UI, performance, and compatibility across different OS versions and screen dimensions. Robust state management, thoughtful networking, and dependable analytics/crash reporting simplify maintenance and iteration post-launch on Google Play.
