Starting with a well-defined product objective and an awareness of device variation, Android app development hinges on outlining the MVP, choosing a suitable architecture, and mapping essential user journeys early to keep the initial release targeted and minimize rework as the app expands.

Once the foundation exists, focus moves to UI uniformity, performance, and compatibility across different OS versions and display sizes. Robust data handling, thoughtful networking, and dependable analytics/crash reporting simplify ongoing support and iteration after the app goes live on the Play Store.
