        String buildCacheKey​(DataSpec dataSpec)
        Returns the cache key of the resource containing the data defined by a DataSpec.

        Note that since the returned cache key corresponds to the whole resource, implementations must not return different cache keys for DataSpecs that define different ranges of the same resource. As a result, implementations should not use fields such as DataSpec.position and DataSpec.length.

        dataSpec - The DataSpec.
        The cache key of the resource.
