Google has recently released a guide to Android app modularization. This guide is designed to bring best practices and recommended patterns for developers to build multi-module Android apps, focusing on mitigating problems that arise when the codebase grows, such as scalability, readability, stability and testability.
After a survey asking for developers about their experience with modularization, where 54% of participants mentioned that it was difficult to find good learning materials about modularization, and almost 95% claimed that the material available on developer.android.com was insufficient, Google decided to launch a guide to Android app modularization.
