AppJoint
Cross module Android development made easy!
...AppJoint uses a small set of annotations and a simple runtime API to decouple modules: one module can declare a method interface, annotate it, and other modules can call it dynamically without direct dependency on the implementation. The tool hides much of the boilerplate of dependency injection or manual wiring of interfaces. It allows progressive modularization: you can incrementally introduce AppJoint in parts of an existing app without rewriting everything. The design focuses on being lightweight and easy to adopt—only a few annotations and calls are needed. In multi-module Android architectures, it helps maintain loose coupling and cleaner module boundaries.
