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". I see that some classes like FileOutputStream and LocalSocket expose a getFD(), but Socket doesn't.How do you get at a true (INET) socket's fd? Alternatively, how do you get at the (private) SocketImpl member of Socket named "impl" (this one exposes the fd)

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.

Android :: Send Intent Attaching Photo From Sd Card As 0 Length File
Aug 17, 2009I know a variant of this question was asked before trying-to-attach-a-file-from-sd-card-to-email But the solution offered, i.e. a reboot doesn't seem to do it for me. I have seen a good number of group postings which support this being a problem. I can only assume the OP for the linked to question made some other changes, possibly to the manifest which allowed his code to work.
The behaviour I am seeing is the Email intent handling the attachment of the jpeg from the sdcard but dealing with it as a 0 length file which is discarded when sent. I have tried setType as jpeg/image and image/jpeg as I have seen it expressed both ways....................

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?
