Launching an Android app starts with a precise product goal and awareness of device variety. Defining the MVP, choosing an architecture, and outlining key user flows early helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is laid, the focus moves to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and trustworthy analytics/crash reporting make the app easier to maintain and iterate after its Google Play launch.
