7. CLEAN ARCHITECTURE: ANDROID DEVS FINAL BATTLE THE CLEAN ARCHITECTURE ▸ Several Architectures with one thing in common: the separation of concerns. ▸ Independent of Frameworks. Independent of UI. Independent of Database. Independent of any external agency. In fact your business rules simply don’t know anything at all about the outside world. ▸ Testable. The business rules can be tested without the UI, Database, Web Server, or any other external element. ▸ The concentric circles represent different areas of software. This rule says that source code dependencies can only point inwards. ▸ Achieve the SOLID principles of robust software.
