This question is old, but now the best is use google Gson.

An example to get custom viewModel.

Class> clazz = new GenericClass>().getRawType();
CustomViewModel viewModel = viewModelProvider.get(clazz);

Generic type class

class GenericClass(private val rawType: Class<*>) {

    constructor():this(`$Gson$Types`.getRawType(object : TypeToken() {}.getType()))

    fun getRawType(): Class {
        return rawType as Class
    }
}
