Gradle include dependencies of a dependency

Question

Scenario

I have two Android libraries:

• Library A
• Library B

Library B depends on Library A and includes it from its build.gradle.

My Android app needs to use Library B and some base classes from Library A. The only success I've had in doing this is including both libraries in my Android app's build.gradle and setting transitive to false.

Question:

Is there a way for me to only add Library B and have access to its dependency from my Android app?

Answer 1

From comments if you need to use library A inside your app and your library A included into B using implementation project(':LibA'), then it won't be a transitive to your main app.

You have to include it into B using api, api project(':LibA').

The api configuration should be used for dependencies that are exported to external modules (transitive dependency). Vice-Versa implementation configuration should be used for dependencies that are internal to the component (not transitive dependency).
