refactor: Start creating core modules (#286) The existing code base is a single monolithic module. This is relatively simple to configure, but many of the tasks to compile the module and produce the final app have to run in series. This is unnecessarily slow. This change starts to split the code in to multiple modules, which are: - :core:account - AccountManager, to break a dependency cycle - :core:common - low level types or utilities used in many other modules - :core:database - database types, DAOs, and DI infrastructure - :core:network - network types, API definitions, and DI infrastructure - :core:preferences - shared preferences definitions and DI infrastructure - :core:testing - fakes and rules used across different modules Benchmarking with gradle-profiler shows a ~ 17% reduction in incremental build times after an ABI change. That will improve further as more code is moved to modules. The rough mechanics of the changes are: - Create the modules, and move existing files in to them. This causes a lot of churn in import arguments. - Convert build.gradle files to build.gradle.kts - Separate out the data required to display a tab (`TabViewData`) from the data required to configure a tab (`TabData`) to avoid circular dependencies. - Abstract the repeated build logic shared between the modules in to a set of plugins under `build-logic/`, to simplify configuration of the application and library builds. - Be explicit that some nullable types are non-null at time of use. Nullable properties in types imported from modules generally can't be smart cast to non-null. There's a detailed discussion of why this restriction exists at https://discuss.kotlinlang.org/t/what-is-the-reason-behind-smart-cast-being-impossible-to-perform-when-referenced-class-is-in-another-module/2201. The changes highlight design problems with the current code, including: - The main application code is too tightly coupled to the network types - Too many values are declared unnecessarily nullable - Dependency cycles between code that make modularisation difficult Future changes will add more modules. See #291.
