Use third party sdk classe in another third party sdk

I am developing android sdk (can be aar file or jar file)

In my sdk i want to use third party sdks that are referenced by the app itself

For example if the build.gradle of the app itself have this line:

com.google.android.gms:play-services-ads:9.4.0

I want to use the play-services-ads classes and methods in my own app without needing to to reference it in my own aar

I thought of one way to do it - using reflection?

Can you suggest other ways?
