Android :: Server Socket Ports Connection Timeout Error
Jul 9, 2010I am playing around a bit with peer-to-peer communication with android devices.I have written a basic program that creates a listening ServerSocket on each phone using the application. Using the application you can also connect to other devices that is listening, by connecting to the remote ServerSocket. Nothing strange about that.My problem is that it seems that the listening port is not open for connection on different devices. I can connect to my HTC Desire, works like a charm. But connecting to a HTC Hero I get timeout, same if I try to connect to the emulator. But connection FROM the emulator to the Desire and FROM the Hero to the Desire works like a charm. Whats up with this? No security apps is installed and both devices(and the emulator) is running 2.1.

Jun 29, 2010We have a simple client server architecture between our mobile device and our server both written in Java. An extremely simple ServerSocket and Socket implementation. However one problem is that when the client terminates abruptly (without closing the socket properly) the server does not know that it is disconnected. Furthermore, the server can continue to write to this socket without getting any exceptions. Why? According to documentation Java sockets should throw exceptions if you try to write to a socket that is not reachable on the other end!

Nov 12, 2009Essentially Im trying to get many many java clients connect to a socket on my ColdFusion server (Using the Socket Gateway). However before i even start to code this, Im a little confused about sockets and their performance. First of all, are sockets meant for many(1000+) clients connecting to one socket (say port 2202) on one server? How is the performance if all there waiting for is basically a ping, or something such that when these clients receive this "ping" they can go get some new data.

Jul 15, 2010I am writing an Android app that should exchange data to a server over Bluetooth, with the server side on a PC running Ubuntu, using the bluez library, in C (or C++).
My Android app fails (IOException) when I try to connect to my server socket on the PC.
Here is essentially what I in the java code (in Android, full eclipse project here: http://dl.dropbox.com/u/2968234/ThinBTClient.zip)
CODE:...........
This throws IOException after a timeout of 10seconds or so.
On the server side (in Ubuntu 8.10), I basically set up a Bluetooth server socket, along the lines described in the example bluez/sdp-register.c
Down below is my C++ program. To compile it do
g++ -I/usr/include/glib-2.0/ -I/usr/lib/glib-2.0/include -o bt_server bt_server.cpp -lbluetooth
I can do the reverse succesfully, i.e. create a server socket in Android and connect from Linux, however this is not what I want to do!
I think either the problem has to do with my config of Ubuntu.

View 2 Replies View RelatedAndroid :: How To Manage Connection To A Socket?
Jun 21, 2010I would like to know what is the recommendation for socket connection management in Android?In our App we would like to be connected to a TCP/IP server when our app is in the foreground or paused. So, create a connection to a TCP/ IP server when the App starts basically, On Create of the launcher activity. However, we do not want to create a new connection and close connection every time an activity is created, paused, destroyed or orientation changed. So, we save the connection object in the App class and the activities will reuse the same connection.Question is when do I close it? I would like to close the socket when the App is "paused", "stopped" or "destroyed". The problem is these messages are not sent in the App context. How can I figure out if the App is in foreground or not? Even the "Terminated" event for an App is not guaranteed to be delivered. So, in that case how do I know when to disconnect?

Android :: Getting File Descriptor From Socket
Jul 23, 2010The documentation for FileDescriptor says it is "The lowest-level representation of a file, device, or socket".

Alternatively, how do you get at the (private) SocketImpl member of Socket named "impl" (this one exposes the fd)

Running netstat -an on the device shows it is listening on 0.0.0.0:1234, but my connections to telnet to <public ip of Android device>:1234 do not appear (and do not receive a SYN,ACK in response). How can I write an application which will open an accessible server socket? Is this possible? I am thinking that either the ISP (mobile carrier) may be blocking this incoming connection attempts or the Android OS is blocking them (host firewall)?

Jan 5, 2010My chat application connects to a server and information is sent/received by the user. When the connection changes, such as 3g->wifi, wifi->3g, losing a data connection, etc, the socket sometimes stays connected for ages before disconnecting. During this time, it's impossible to tell if the connection is still active, it seems as if messages are being sent just fine. Other times, when sending a message, it will throw an IO error and disconnect.
Apart from implementing code to detect connection changes and reconnecting appropriately, is it possible to have the socket immediately throw an IO exception when connectivity changes?
