why i should add dependencies that in aar file to my project?

Question

I created the my Android Archive Library aar file that have it's own dependency in it's Gradle. I use this library in many projects of mine, but why I should add aar dependency to my application dependencies? as we know benefit of using aar vs jar is aar can have and hold it's own resources and dependencies.

Answer 1

The aar file doesn't contain the nested (or transitive ) dependencies and doesn't have a pom file which describes the dependencies used by the library.

It means that, if you are importing a aar file using a flatDir repo you have to specify the dependencies also in your project.

You should use a maven repository (you have to publish the library in a private or public maven repo), you will not have the same issue.
In this case, gradle downloads the dependencies using the pom file which will contains the dependencies list.
