Android Question Serversocket after disconnect is still connected

welu1805 · Apr 12, 2016

Hi all,

I use for testing of AsyncStreams a small app similar to AsyncStream Tutorial from Feb, 3, 2011.

At first the server starts. Then the client connects to him. In a Button_Click I can get the state of the socket from the server: True - OK.

Now the client disconnects with AstreamClient.Close and SocketClient.Close
The Button_Click still shows True.

Even if I close the client app, the server button for connected still says True.

Is this a mistake in my minds or a bug?

Are you handling AsncStreams_Error and Terminated events?

welu1805 · Apr 12, 2016

No, in the sample app I don't handle the events.

Now I used AStreamServer_Terminated. If the client disconnect the connection, this event is fired.

But I have some clients connected to one server. The AsyncStream objects are in a list object - all with the same event name. How can I determine in AStreamServer_Terminated. which client this is?

The serversocket objects are also stored in a list. My idea was, to find the closed connection with socket.connected = False

You can use the Sender keyword to find it.

You don't need the ServerSocket at all. Note that a single ServerSocket can create many clients.

Go over this B4J example: https://www.b4x.com/android/forum/threads/b4j-cctv-example.34695/#post-203347
It handles multiple AsyncStreams.

Thanks Erel for your tip with Sender keyword. I use it to find the position in the lists of AsyncStreams and sockets. Then I remove both entries.
