Libs add dependency android

Question

I'm facing an issues about import aar file, which compile another one, and IDE request compile them also. Here is my problem: I create a module, it's "mylibs". Mylibs compile another one. In my case is timber (libs about logging). Then i create a aar file from Mylibs and import it in mainProject by below code:

compile(name: 'mylib', ext: 'aar') { transitive = true }

After rebuilt, IDE request me must be import timber also. I dont understand why i need import timber lib ?

Answer 1

aar files do not include dependencies. If they are shipped through a repository, there usually is a pom file in the same repo which describes the dependencies. In this case gradle can resolve transitive dependencies automatically.

But if you ship an aar locally, there are no informations on dependencies available, so you have to include them manually.
