• Method Detail

  • status

    void status(int major_version,
              int minor_version,
              int code,
              String reason_phrase)

    Called after status line has been sucessfully processed.

    Parameters:

    major_version - HTTP version advertised by server. major is the part before the "."

    minor_version - HTTP version advertised by server. minor is the part after the "."

    code - HTTP Status code. See RFC 2616.

    reason_phrase - Textual explanation sent by server

  • headers

    void headers(Headers headers)

    Called after all headers are successfully processed.

  • data

    void data(byte[] data,
            int len)

    An array containing all or part of the http body as read from the server.

    Parameters:

    data - A byte array containing the content

    len - The length of valid content in data Note: chunked and compressed encodings are handled within android.net.http. Decoded data is passed through this interface.

  • endData

    void endData()

    Called when the document is completely read. No more data() callbacks will be made after this call

  • certificate

    void certificate(SslCertificate certificate)

    SSL certificate callback called before resource request is made, which will be null for insecure connection.

  • error

    void error(int id,
             String description)

    There was trouble.

    Parameters:

    id - One of the error codes defined below

    description - of error

  • handleSslErrorRequest

    boolean handleSslErrorRequest(SslError error)

    SSL certificate error callback. Handles SSL error(s) on the way up to the user. The callback has to make sure that restartConnection() is called, otherwise the connection will be suspended indefinitely.

    Returns:

    True if the callback can handle the error, which means it will call restartConnection() to unblock the thread later, otherwise return false.
