Project to grow beyond a certain threshold, the scalability and build time Aĭominating factor is the size of the codebase.
Repositories and data sources into standalone modules. But as it grows, it might be necessary to separate For example, in a small project it’s ok to put the data layer Might end up with yet another monolith and miss the benefits that modularity Too coarse-grained: Conversely, if your modules are growing too large you.If overheadĬounteracts scalability improvements, you should consider consolidating some Results in a cumbersome codebase that is difficult to maintain. Keep configurations consistent across modules. AĬomplex build configuration makes it difficult to Too fine-grained: Every module brings a certain amount of overhead in theįorm of increased build complexity and boilerplate code.Too fine-grained will make the overhead a burden, and going too coarse will Take into account the size of your codebase and its relative complexity. Modularized codebase, you should decide on a level of granularity. A more granular codebase has more, smaller modules. The granularity of your codebase is the extent to which it is composed of Some Gradle functionalities such as incremental build, build cache or parallel build, can leverage modularity to improve build performance.
#ANDROID MULTI CODE#
A testable code is one where components can be easily tested in isolation. Testability characterizes how easy it is to test your code. Isolated code is easier to read and understand. A module can have a dedicated owner who is responsible for maintaining the code, fixing bugs, adding tests, and reviewing changes.Įncapsulation means that each part of your code should have the smallest possible amount of knowledge about other parts. In addition to enabling autonomy, modules can also be used to enforce accountability. This empowers the contributors through greater autonomy. A properly modularized project will embrace the separation of concerns principle and therefore limit the coupling. In a tightly coupled codebase a single change can trigger a cascade of alterations in seemingly unrelated parts of code. Theįollowing benefits might be achieved with other techniques but modularizationĬan help you enforce them even more. The benefits above are only achievable with a modularized codebase. Play Feature Delivery uses the advanced capabilities of app bundles, allowing you to deliver certain features of your app conditionally or on demand. You can mark everything but your public interface as internal or private to prevent it from being used outside the module. Modules enable you to easily control what you expose to other parts of your codebase.
#ANDROID MULTI FULL VERSION#
For example, a :feature:news can be a part of the full version flavor and wear app but not part of the demo version flavor. The functionality that a certain module provides may or may not be enabled in a particular app. Apps should be a sum of their features where the features are organized as separate modules. Modularization enables opportunities for code sharing and building multiple apps from the same foundation.
The maintainability and overall quality of a codebase. The benefits of modularization are many, though they each center upon improving Figure 1: Dependency graph of a sample multi-module codebase Benefits of modularization Subproblems, you reduce the complexity of designing and maintaining a large By dividing a problem into smaller and easier to solve Modularization is a practice of organizing a codebase into loosely coupled and Modularization is a means of structuring yourĬodebase in a way that improves maintainability and helps avoid these problems. In size without its maintainers taking active measures to enforce a structure This comes as a result of the codebase increasing In an ever-growing codebase, scalability, readability, and overall code quality Note: This page assumes a basic familiarity with the recommended appĪrchitecture. Guide encompasses best practices and recommended patterns for developing A project with multiple Gradle modules is known as a multi-module project.
