    Note that closing an InputStream that was generated from an HttpConnection does not guarantee that the HttpConnection will be closed as well. For extra insurance if you are not in control of where the InptStream gets closed, you can wrap your InputStream in a ConnectionInputStream instance (extends DataInputStream). Using this class guarantees that when close() is called on the InputStream, close() will be called on the supplied connection as well. The constructor methods are:

    • ConnectionInputStream(InputConnection connection) throws IOException
    • ConnectionInputStream(InputConnection connection, InputStream inputStream)

    There is also a ConnectionOutputStream available for OutputStreams.
