Patterns for Safe Refactoring of Android Apps
summary
Shows a concrete, incremental 5-step recipe to refactor an Android MVC app into Google’s Recommended App Architecture. Steps: extract an OkHttp remote data source, add a repository, replace AsyncTask with ViewModel + LiveData + coroutines, and finish with data binding and UI tests. Emphasizes writing unit and UI tests before swapping implementations, making each change non‑destructive, and provides a sample repo where each step compiles and preserves correct behavior.
