Starting Android app development involves a well-defined product target and awareness of device variation. Clarifying the MVP, choosing a software architecture, and outlining key user journeys early on keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus moves to a consistent UI, performance, and compatibility across different OS versions and display sizes. Robust state management, thoughtful networking, and trustworthy analytics/crash reporting ease maintenance and iteration after launching on Google Play.
