Cant get Android example to work

[Anonymous]

Dear All,

Need some help with setting up the most basic example of the chat example locally, I run the Android example and set it as server and also run the ExamplesConsole.exe in which I choose the first option “Basic – Message Send”, when I try to send some text to the correct IP address as the Android stated it is listening to I dont get to see the text message in the Android application:

however when I close the ExamplesConsole.exe the Android application writes the following message:

so the connection has been made earlier but the text was not shown?

Please help me with this..

Thank you all in advance!
Best,
R.

Heya R,

Are you using some kind of emulator for android? If so it is common that many of them are quite buggy when using network connections. Also ensure that all firewalls have been disabled at both end of the connection, or atleast that they allow the required ports through. You could also try enabling logging on the consoleexample to see what is happening when you try to send a message.

Kind regards,
Marc

Hi Marc,

Thank you for your reply.

The following is the log output for a test between an Android Galaxy device and a PC running the Console example, in this test I’ve sent a message from the Android device to the PC, the log created but no message arrived:

According to the logs, everything appears to be working correctly. The last line refers to the packet handler that should write the message to the console – Triggering handlers for packet of type ‘ChatMessage’.

The problem has to be something basic in your setup, i.e. something that is causing the messages to not be printed to the expected console window, or you are breakpointing in the code and not allowing the packet handlers to run.

Sorry I can’t provide anything more specific but according to the logs everything looks good. Perhaps try two console applications first to ensure that works before adding the complication of a mobile device.

Please let me know how you get on.
