Just for your information, we now use the «new» MPP plugin and release on jcenter (no maven central) because of the javadoc limitation.
We also had to change the structure of the artifacts. And, if you use gradle 6, you can declare your dependency in a more simpler way. See https://github.com/data2viz/data2viz-examples/blob/master/tutorials/barchart-android/build.gradle#L102
There is no “-android” suffix, it uses the module definition to find the correct variant of the artifact.
