SendMessageListener - SendMessage Android_StockListDemo

bbittiker

Can anyone provide an example of how I would send a message back from the client, specifically in the Android_StockListDemo?

           try {
                lsClient.getLSClient().sendMessage("test");


            } catch(Exception e) {
                Log.e(e.getMessage());
            }

Gives me com.lightstreamer.ls_client.PushConnException: java.io.FileNotFoundException: http://192.168.1.148:8080/lightstreamer/send_message.txt

I am pretty sure I need to configure MessageInfo and SendMessageListener but I am not sure how. Thanks.

Hi,

The error you got is quite unexcpected.

First of all, I assume that the getLSClient call returns a valid and connected LSClient instance (you can't send messages to the server if you don't have an open session).

Can you please post your server log?

It is not necessary to use a MessageInfo to send a message.
You use such class if you need your messages to be handled in order by the server and/or if you want to know what's the outcome for the sent message. Otherwise you can use the basic sendMessage call that has only one String parameter (i.e.: string to be sent).

I had to turn on the logging in my metadapter, the relevant bits:

12-Nov-12 08:25:17,128|ERROR|LightstreamerLogger.pump.messages|SERVER POOLED THREAD 4 |Error in message forwarding for XXXX_UNICAST: Wrong message received

My problem was with the message format. I have formatted it correctly and sendMessage is now sending messages from the android client to the server and pushing them to the other clients. Thanks for your prompt response and suggestions.
