public void onFrameError(WebSocket websocket,
                         WebSocketException cause,
                         WebSocketFrame frame)
                  throws Exception
Description copied from interface: WebSocketListener
Called when a WebSocket frame failed to be read from the WebSocket. Some WebSocket server implementations close a WebSocket connection without sending a close frame to a client in some cases. Strictly speaking, this behavior is a violation against the specification ( RFC 6455 ). However, this library has allowed the behavior by default since the version 1.29. Even if the end of the input stream of a WebSocket connection were reached without a close frame being received, it would trigger neither onError() method nor onFrameError() method. If you want to make this library report an error in the case, pass false to WebSocket.setMissingCloseFrameAllowed(boolean) method.
Specified by:
onFrameError in interface WebSocketListener
Parameters:
websocket - The WebSocket.
cause - An exception that represents the error. When the error occurred because of InterruptedIOException , exception.getError() returns WebSocketError.INTERRUPTED_IN_READING . For other IO errors, exception.getError() returns WebSocketError.IO_ERROR_IN_READING . Other error codes denote protocol errors, which imply that some bugs may exist in either or both of the client-side and the server-side implementations.
frame - The WebSocket frame. If this is not null , it means that verification of the frame failed.
Throws:
Exception - An exception thrown by an implementation of this method. The exception is passed to WebSocketListener.handleCallbackError(WebSocket, Throwable) .

                    throws Exception
