Covers several Android App Architecture such as MVP, MVVM, MVC. Demonstrates how specific architecture can help solving problems with different set of incoming parameters, such as absence of API or UI/UX designs.

clarify that MVC, MVP, MVVM (or any other) are not architecture patterns but design patterns for the presentation layer (because the true architecture as such is ‘the layers architecture’) What are the currently widely used Android Application Architectures?
fun requestItems(): List<String> = listOf() } class DataRepository { private val roomDatabase = RoomDatabase() fun requestItems(): List<String> = roomDatabase.requestItems() } // Inversion of control applied class DataRepository2(private val roomDatabase: RoomDatabase) { fun requestItems(): List<String> { val result = roomDatabase.requestItems() return result } }
fun requestItems(): List<String> } class DataRepository3(private val dataPersistence: DataPersistence) { fun requestItems(): List<String> { val result = dataPersistence.requestItems() return result } } class RoomDatabase2 : DataPersistence { override fun requestItems(): List<String> = listOf() }
