        Parameters
        ----------
        name : str
            The name of the distribution. If a dist with this name already '
            exists, it will be used.
        ndk_api : int
            The NDK API to compile against, included in the dist because it cannot
            be changed later during APK packaging.
        archs : list
            The target architectures list to compile against, included in the dist because
            it cannot be changed later during APK packaging.
        recipes : list
            The recipes that the distribution must contain.
        force_download: bool
            If True, only downloaded dists are considered.
        force_build : bool
            If True, the dist is forced to be built locally.
        extra_dist_dirs : list
            Any extra directories in which to search for dists.
        require_perfect_match : bool
            If True, will only match distributions with precisely the
            correct set of recipes.
        allow_replace_dist : bool
            If True, will allow an existing dist with the specified
            name but incompatible requirements to be overwritten by
            a new one with the current requirements.
