How to include an external jar file to aar file in Android

问题

I want to develop a solution that allows me to use an external jar library in an SDK generated in aar file for an Android project.

What I have as inputs :

SDK : "de.xx.sdk:xxx-android-v1.0.0"

external library : "libs/xxxx-v1.0.0"

what I found out in my investigation is how to exclude a library from project like the following :

implementation('android.arch.work:work-runtime:1.0.0') {
        exclude group: 'com.google.guava', module: 'listenablefuture'
    }

Is there something similar to write in gradle file how to include a library instead of exclude it.

implementation('de.xx.sdk:xxx-android-v1.0.0') {
        include group: 'libs/xxxx-v1.0.0'
    }

Thank you

You should try to put your jar into a module (File->New->New Module->Import JAR/AAR Package) and then add the module as a dependency.

implementation('de.xx.sdk:xxx-android-v1.0.0') { include group: 'libs/xxxx-v1.0.0' }

You can't do it in this way.

Something like exclude group: 'com.google.guava', module: 'listenablefuture' is possible because you have an artifact with a pom file published in a maven repo.
In the pom file there is the list of the transitive dependencies, and if there is a match with the group/module gradle is able to exclude it.

To achieve something similar, you have to publish the lib a in maven repo with a group/name (it can't be lib/....v1.0.0)
