```
    Create a media entity with the specified content in the target system. If the entity has non-stream structural properties in addition to the key properties and media content, such as label in the examples below, then this function will send two requests to the server: a first request to upload (POST) the media stream, and a second request (PATCH/PUT) to update the non-stream properties. It is not currently supported to make these two calls atomic. Caution: Having too many threads simultaneously creating streams may result in out-of-memory conditions on memory-constrained devices.
    
    Specified by:
    
    createMedia in interface DataServiceProvider
    
    Parameters:
    
    entity - Entity to be created.
