Dec 7, 2009I wondered if there could be a specific reason why a server socket could refused a client request connection , the server running on one android device the other on the emulator?

View 10 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?

The Droid can make connection requests (Http, Telnet, raw sockets) in 3G, but I cannot get the Droid to accept a socket connection in 3G mode. I was told by Verizon that a special license may be needed to accept socket connection requests and they would send me some information. So far none has been received. If anyone knows how to program the Droid to accept socket connection requests over 3G, please respond. Also if anyone knows why this not allowed please respond.
View 10 Replies View RelatedAndroid :: Detecting Socket Connection Failure
Apr 1, 2010I am working on an app that uses a Socket to connect to a controller over TCP. The protocol library was written in Java and I am implementing it in android via a Service. where the Connection class is a Thread that handles the communications with the controller. It's where the Socket lives.I'm using the Preferences mechanism to store the IP and Port. If I feed the Socket the correct IP and Port, the Connection Service works beautifully. However, I am trying to simulate a user entering the wrong information and having the connection fail. The ultimate goal is to present a dialog and offer the ability to "reconnect" or "update settings". However, when I enter a wrong Port number, the application simply hangs.I was under the impression that Threads executed concurrently so I've tried moving the call to start the Connection Service to a Thread, but it still hangs the application.

Do anybody know any other way to keep communication channel open? or any optimization in using socket?

Android :: SSL Socket Blocks On Read While Changing Connection / Is It A Bug?
Feb 19, 2010I assume that when I do a read on the inputstream, it blocks until it gets more data to read.
I also assume that when the connection is closed, the read throws an IOException.
The problem is that sometimes when I change the connection from carrier to WiFi or from WiFi to carrier, the read just gets stuck and never throws the IOException.
The SDK is 1.5 and the phone a HTC Hero.
This behavior is quite ugly for me because I need to stay always connected.
Does someone else have ever seen this problem ? Is it a bug or am I the bug?

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.

Communicate To WiFi Enabled Arduino Board With Static IP - Socket Connection
Feb 3, 2012So Im writing an application to communicate to a Wi-Fi enabled Arduino board with a static IP...
This is what Im trying to do...
1.) Enter Ip and Host
2.) Connect
3.) Simply send either a "0" or "1" to the arduino board
There are two activities at the moment, one to enter the IP and port of the Board (which is set from the board itself) and one to send data to the board. When i comment out the connection methods in the Communicator class the app swithches activities without any issues, but when i un-comment them and attempt to connect, the app immediately closes after i attempt to connect.

View 3 Replies View RelatedAndroid :: Java Socket Not Throwing Exceptions On Dead Socket?
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.

Sprint HTC Hero :: Phone Refused To Make Calls / Had Service
Dec 22, 2009I had a weird issue that has sprung up twice now with making phone calls and I wanted to see if anyone else was experiencing the same thing. Visually everything looks like it is functional with my phone service on the phone. I have bars, nothing out of the ordinary. However, I can't make any outbound calls either through my contacts or by manually dialing. I the number pad and it makes the response noise but doesn't actually type the number. In contacts, I hit call and the same thing happens. The fix I have found is just to soft boot the phone. Now I hear you all saying "No big deal, just restart." Yeah, it is no big deal unless I have to make a call in an emergency say calling 911 or things of that nature. Waiting for 5 minutes for my phone to reboot in an emergency can cost lives. I know I am being a little dramatic, but c'mon, at the end of the day, it is a phone and it is having trouble making calls.

Nov 7, 2010I own a Samsung Galaxy S SGH-i896 and I decided to try and put on Cognition for a test, but before that, I did a android backup using ROM Manager. Now I thought this would save me in any situation...
So I flashed it over to Cognition, and it refused to connect to Rogers (as I expected) however, when I went to restore back, I would still get the AT&T start up, and the video was replaced by text that said "Android" in a weird font. I managed to flash it back to a stock AT&T ROM which worked well, but still wouldn't connect to the Rogers network.
I had tried to get into the ClockworkMod Restore Screen which I did finally get. I wiped all user data and cache, and restored from my backup...
Only to find my AT&T boot screen still there instead of the i896 screen and Rogers screen which would usually show. What can I do about this issue? Is there some kind of firmware or ROM from Rogers I need? I have a Rogers Stock firmware but that didn't seem to work either
